How to Get Rid of Brown Recluse Spiders

Q: have found 2 brown recluse in my basement (I have a teenage son down there)Is Deltamethrin the best product to use? Are there any other recommendations?

A: The first and foremost step you want to take is to thoroughly clean your basement. You need to clear out as much clutter as possible to eliminate possible shelter for the brown recluses. If you have any leaky pipes or anything that may act as a source of moisture, it needs to be removed and cleaned up as well. In terms of pesticides, LambdaStar 9.7% CS  is a great product to use on brown recluses and its active ingredient is Deltamethrin. We recommend using the Suspend SC with several glue traps for the most coverage.

brown-recluse-spider-pest-control22HOW to GET RID of BROWN RECLUSE SPIDER – POSIONOUS SPIDERS

A Brown Recluse Spiders reclusive characteristic is that they seek hiding places and shelter. They are very adaptable and will still be active in temperatures from 45F to 110F, meaning that they will still be active during the winter. Brown recluse spiders have soft bodies with yellowish-tan to dark brown color. They can vary from 1/3- 1/2″ in length and can be over 1″ in diameter including the legs. They can be identified by a dark brown violin looking shape mark (please refer to the picture for identification). The brown recluse spider spins a web that is white to gray in color. They are active at night and usually eat other insects as in cockroaches and other small insects. Brown recluse spiders can survive up to 6 months without food or water.


Brown recluse spiders can be found usually in indoors, bathrooms, bedrooms, closets, garages, basements and cellars. They can also be found living in or around the duck work or registers on above-ceiling duct works. Brown recluse spiders can be found outside in storage houses or buildings where things are stored and they MAY also be found in sheltered corners with debris, wood piles, and under loose stones. They can make webs under furniture, appliances and carpets, behind baseboards and door facings, even in corners and crevices.


People usually get bitten when they change clothes or when they put their hands in their pockets or even putting on their shoes. The pain from the bite will not be as intense immediately, but within 8-12 hours the pain will become intense.

  1. The person might have fever, chills, nausea, and joint pain.
  2. The person might become restless within 24-36 hours after they have been bitten
  3. The area of the bite will swell because the tissue will become inflames and it would be hard to touch. The venom of the brown recluse spider has an enzyme that will destroy cell membranes in the bitten area.
  4. After a few days, a huge ulcerous sore will form. If the wound is open from the bite, it may range from the size of an adults thumbnail to the size of the hand. The sore heals extremely slowly; it will take about 6-8 weeks to heal and it will leave a large, disfiguring scar. If possible, you would need to take the brown recluse spider to the doctor to get identification immediately.
  5. The person should apply an ice pack to relieve the swelling.

The brown recluse spiders only bite when someone or something disturbs their spot as a defense mechanism, so if you find a spider, please do not touch it with bare hands or feet.


If you live in the area where brown recluse spiders are common, you will need to shake out your clothing and shoes be dressing just in case a brown recluse spider is hiding in them. You will need to inspect any items that you are going to use and you will have to WEAR GLOVES the whole time when you are going to garden, handle firewood and pine straws. You should not go outside barefooted because the brown recluse spider might bite your foot or you might step on one. You should also eliminate much clutter as you can in the storage areas and also vacuum and dust around the windows, corners, and under furniture often.

Crack and Crevice Treatments:
This treatment is generally applied with a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap ) and dust (DELTA DUST), and aerosols ( CY-KICK AEROSOL, ALPINE AEROSOL) to be applied to small cracks and crevices in a structure with spiders may live and hide.

For liquid spray application, you will need to have a pressure sprayer or a gallon sprayer (CHAPIN 1 GALLON SPRAYER). For (LambdaStar 9.7% CSFenvaStar EcoCap ) you will need a low pressure system with a pinpoint or variable pattern nozzle to apply the spray mixture to areas such as floors, cracks and crevices, in and around baseboards, walls, expansion joints, around your windows, and under your furniture. You will need to apply using the amount that is said on the label and may need to reapply if needed.

The dust application is simple. However, when using dust please be cautious especially when children and pets are present. Use dust only in areas where it is hard for them to reach. The DELTA DUST, you will need to use a BELLOW BULB DUSTER . When using a BELLOW BULB DUSTER for DELTA DUST, you will need to fill the duster with the dust as directed in the label and apply DELTA DUST to cracks, spaces or bearing joints between the wooden members of the structure. Apply lightly and uniformly to the infested area. DO NOT OVER USE DUST. The aerosols are used by spraying into the crack and crevice.

Since aerosols and liquid sprays are liquid be cautious if you are spraying near any electric equipment or outlet.

Directly getting rid of the web that the spider has made already you will need to use COBWEB ELIMINATOR. You will directly spray the COBWEB ELIMINATOR on the web and it makes it easier to remove the web without leaving any of it behind. It also discourages the reformation of webs. The COBWEB ELIMINATOR has a mildly acidic odor to it, but it is indicating that the product is effectively working.

Barrier Treatments:
This treatment is applying a liquid spray to zone around on a structure that any pest might enter the zone. These are sometimes called a perimeter treatment where soil areas are adjacent to a structure as well as a portion of the lower foundation wall next to the soil are treated (LambdaStar 9.7% CS).

Barrier treatments or Perimeter treatments are used just around the structure of your home to create a barrier for you home. We suggest that you use a gallon sprayer as well (CHAPIN 1 GALLON SPRAYER). Using the directions of the amount and the rate that you should use, apply a continual band of insecticide around a building foundation and around windows, doors, service lines entrances, eaves, vents, and other areas can greatly reduce the potential for entry by pests. Also apply a band to the soil 6-10 ft. wide around and adjacent to the building and treat the building foundation to a height of 2-3 ft. where peats are active and may find entrance. Apply as a coarse spray treatment to thoroughly and uniformly wet the band. For better results, this treatment needs to be done regularly to reduce the amount of insects and to keep your house insect free.

    We caught a spider that I think may be a brown recluse. I took photos of it and wondered if you would be able to tell me for sure if it is one or not.

    Thanks for your help.

    Hello Karen,

    Sure, we would be glad to help! Just send the pictures to We’ll take a look at them and let you know!

    I was seeing a lot of spiders in my home, so I had someone come and spray about 5 weeks ago. They also put “sticky” traps in various locations in the house. Since, I have caught a couple brown recluses in the traps (basement laundry area and living room by the fireplace) and have killed live spiders in both upstairs bathrooms and the kitchen. I am totally freaked out, especially since I have a 3 month old baby. I had another company come and spray the whole house and “dust” the attic. I have cleaned and inspected the upstairs and don’t see anything else except the fireplace. All throughout it, there are small webs, and I even saw a dead baby brown recluse on the sticky trap near it. I really would love to just move out of my house!! Help! I keep having nightmares about spiders and I just don’t know what to do. Can I or should I do anything else? Can I relax now that I’ve had the house sprayed a second time? I’ve heard that brown recluses can be impossible to kill. Can I ever feel safe in my home again? My baby will be crawling in a few months and I don’t feel like I can let him down on the floor. Any suggestions would be greatly appreciated!

    Unfortunately, spiders are a difficult pest to get rid of.
    I would recommend using Demand CS, as it is micro-encapsulated so it’s safer to use indoors,
    and lasts twice as longer than other pesticides.
    I would also recommend using some Trapper Moniter Insect Traps.
    Just place them around your home where you most commonly see the spiders.
    I’m so sorry to hear about your misfortunes, however,
    if you stay consistent with your treatment, you should be fine in due time.

    Hi, My son is currently in the Helmand Province of Afghanistan. He said his mud shelter they are occupying is full of brown recluse, black widows, flies and rats. He has just arrived there and has 7 months left. I would like to know if you can tell me what would be the best product to send to him to keep these unwanted creepy crawling creatures at bay? Thanks, JJ

    Hello, that sounds so uncomfortable. If he was located in this country, we would be able to help you, but from my understanding, we can’t ship out products internationally. So even though we have products available, we wouldn’t be able to ship them out to him. The chemical content in most of our products may be the reason why the country will not let our products in. I’m sorry I could not help out in a better way!

    I’ve got a serious problem. First of all, you should
    probably know that I have a serious phobia of spiders in general. It’s so bad that it actually affects my life in many ways and puts a lot of limitations on me. We live in Missouri and have recently moved outside of a big city and onto some land in the country. Naturally I expected to see more spiders in general- but this is
    out of hand. I saw a few brown recluses early this
    spring and decided to call Orkin. They’ve been out
    twice because I keep finding them. They have set 32 sticky pads up in my house because they say that you can’t kill them
    with spray. He said they’re also called the dirty spider because they don’t clean themselves so they never ingest the poision supposedly. However, the sticky things have worked very well. Which is why I’m alarmed; in a matter of four weeks we now have confirmed that there are over 25 brown recluses on those. I hate to think about how many didn’t cross the path of a sticky pad. I literally am losing sleep over this. I check my sheets and our daughters crib every night. I sleep with long sleeve shirts and pants on. I sleep with my light on hoping they’ll stay in the dark. I’m with the lady above; I’m completely ready to move. I really cannot handle this. What else can I do besides the Orkin visits? Are they correct about the pesticides? I’ll do what ever it takes to stop this, anything at all. If there’s any advice you could give I would greatly appreciate it. Thanks!

    Hello Sally,
    To our understanding, sticky pads are a good method of control. However, we are pretty sure that liquid concentrates will provide a residual contact kill for spiders, including the brown recluse. I have called several different manufacturing companies that produce different liquid concentrates that will kill brown recluse spiders. Backed By Bayer has three different liquid concentrates that will kill the brown recluse including Suspend SC, Tempo, and Temprid SC . Also, Sygenta has two products that targets spiders including the brown recluse called Demon Max and Demon WP. All these products that are listed are the top products in the market right now for general pest control as well as spider control. They will all dry on clear except for the Demon WP which will leave a visible residue. However, the Demon WP may be the best product to use because it may provide a longer residual. All the products that are linked have products labels which provide the dilution rates for spiders. Talking to the manufacturing companies, they have both said that when they label “spider,” it does target all species including the brown recluse and even the black widow. The behavior of brown recluse spiders can be found on our brown recluse main page which is linked here: – The bottom of the brown recluse category page lists where to look for them, how to get rid of them, and some other biological characteristics. If you have any questions though, you can always give us a call at 1-800-788-4142. We will love to help you! Good Luck!!

    Can you please tell me the safest method to rid these spiders from the inside of my house I found one tonight under my pillow and today under my 2 year olds blankets and I don’t even feel safe sleeping in my house especially with my 2 babies

  10. 10

    That certainly sounds like an unwanted and scary pest! The best way to fight brown recluses is to be careful and to prevent them from living anywhere. Cover up any holes or creases in any boxes using duct tape and always check your clothes and shoes before putting them on. In terms of killing methods, I would recommend a glue trap to catch the ones wandering around your and your child’s bed. You can also use Demand CS to apply around the bed to hopefully prevent more brown recluses climbing up bed posts. However, most pesticides kill spiders effectively and don’t always list brown recluses as a target pest. I would recommend that you look through Pest Mall’s available brown recluse pesticides and then call the manufacturer to make sure it will definitely kill brown recluses. If you ever need any help, please call us at 1-800-788-4142.

    We just moved to a rental home in Missouri, and we are battling these brown recluses. I am so ready to move, but I’m concerned that there may be spiders in any of the boxes we have here in the storage area. I really want to just get rid of anything we don’t absolutely need…because I don’t want to bring any to the next place we move. We have an exterminator who has sprayed twice and set out some traps. I’ve found all sizes of live and dead recluses (baby to large adult) around every level of the house. We have 3 young children and I don’t know which is worse ~ the spider or the insecticide! She actually is coming today to set off some “fog” bomb in the drop ceiling downstairs or something, and I’m nervous about going back home and letting the children around the residue. Any advice on these “fog bombs” or how to get rid of them on every level?

  12. 12

    I’m having the same problems as listed above… Only I live…….in a field…….in Tennessee……..SURROUNDED by piles of useless, dry, wood, which my landlord swears he’s gonna build somethin with.. :/ I’m seeing a lot of dead ones around the house, however to my dismay, when I inquired about these ‘dead ones’, I was told they’re actually the empty shell where the spider has molten and gotten BIGGER.. Bigger?? I can barely deal with the thought of a small one being in my home (as I’m 9 months pregnant, due any day) let alone the ones that are already here to get BIGGER!! I have killed some in the bathroom at night since I’m up going potty all night, found several ‘shells’ in the living room around the baseboards, and caught a really big one (WAAAYYY bigger than an INCH in diameter, btw) what can I use that is safe for me and baby besides only the sticky’s? Because that seems like a drawn out type process and I’m looking for more of an immediate affect? Also, will spraying and trapping, etc. kinda upset em and make them more prevalent and noticeable? Jw?

    Sorry to hear about the frightening experience you both are coping with. Here’s the misconception over pest bombs. Many people assume that bombs will reach all the hard to reach crack and crevices because it’s in a gaseous form, so after a couple bombs they assume they have gotten rid of the infestation, only to see them re appear within a couple days. Brown Recluse spiders love to harbor in undisturbed areas and can be found in shoes, clothes and bedding during the night. It is recommended to move your bed away from the wall so that the spiders may not have easy access to the bed. Shoes and clothes should also be shaken off before wearing. Before applying pesticide it’s always best to begin with glue boards so that you can get an idea of their harboring area. Following the glue boards or along with the glue boards you can use a long residual insecticide that will help you to control their numbers. When targeting the brown recluse spiders it also important to control the general population of pests around the home. As long as there is a food source for them, they are likely to stay. When their food source is eliminated, they are likely to move out and relocate to other areas. You will need to do an outdoor treatment as well as indoor treatment. Recommended products would be Delta Dust, Drione Dust, Cynoff WP, Cyper WP, and/or Demand CS.

    Last night, I saw what I thought was a baby mouse run across the floor of my room. Although a mouse isn’t that welcome of a guest at my house, it’s better than what I found out the “mouse” actually was. It was a massive(about the diameter of a tennis ball) brown recluse. I live in the middle of nowhere in Tennessee, and surrounded by fields and dense, wood-like areas. At first I thought it was a large wolf spider, because those are common around here. After the spider was smacked a few times with my shoe, I saw what looked like a violin-shaped marking on it’s head. Do wolf spiders have markings? And how big do brown recluses get? I also think that I just killed a smaller one. Is that bad to see more than one in two days time? I’m not one to be freaked out by spiders, and it would help if the mouse-spider-thing I killed wasn’t a brown recluse.

    Hi, I am in the same boat as most everyone else. I am almost 6 months pregnant and my husband and I have been noticing brown recluse spiders primarly in the room that we are planning to be our nursery. We had a problem with them last year but we sprayed inside and set off foggers as well and did not catch anymore on the spider traps. This year the same thing we kept noticing them in the spare bedroom and we did the same thing we did last year and in the last month we have caught a baby spider on the trap. I killed another baby recluse that was crawling across the bed in broad daylight and my husband had another small one crawling on him in the bed last nite. I have a recluse phobia since my mom got bit two years ago. She is fine but had to take steriods and got reoccuring bites from it as well. Not sure what to do, but our baby will be here in Nov. and we really want this taken care of before he gets here. Can anyone purchase delta dust or the other powders that have been listed?

  16. 16

    We have a pest/termite contract with Terminex. They have found brown recluse spiders and are recommending a dust treatment that will go in every outlet/lightswitch in the house. Cost will be $800. This sounds pricey- should I try one of your kits first? Why is their treatment so expensive?

  17. 17

    Hi Kim,

    Most of the cost from extermination services comes from labor fees. Basically, you have to pay a lot because the exterminators have to come to your home and apply pesticides in a lot of hard to reach places. Our kits and even a dust product like Delta Dust will get the job done as well as any product your exterminator uses at a fraction of the cost; you just have to be willing to apply it yourself. However, if you encounter any problems or have any questions while treating for the brown recluses, you can always contact us and we’ll be happy to help you out :) Whether your decide to go with your exterminator or us, I hope you manage to get rid of those brown recluses! Good luck!

  18. 18

    Hi Anna,
    I’m really sorry about the late reply. It sounds like, unfortunately, that what you saw was indeed a brown recluse spider. Wolf spiders do have markings, but that violin marking is the key identifying characteristic of a brown recluse. It doesn’t sound like there’s any need for alarm though. However, just to be safe, I think you should buy some glue traps to lay around your home. If you’re seeing more and more of these violin spiders, you definitely want to take chemical action, but if not, then the glue traps should be a sufficient defense.

  19. 19

    Hi Jennifer,
    Well, first off, I think you might want to change which room you make the nursery in! Brown recluse bites are definitely no fun for adults, but for small children and the elderly, they can be fatal. You can purchase the products we mentioned in this post as long as your state doesn’t have restrictions and as long as you don’t misuse the products or sell them for profit (but I highly doubt you would). The Delta Dust is great to use with brown recluses and so is a liquid insecticide like Suspend SC. When your baby is born, I recommend to switching to just a liquid insecticide and glue traps, for the safety of your baby. Good luck!

    I bought a house in eastern KS. not quite a year ago, and after killing a few of these spiders in the middle of the day in a well lit room, I decided to set out some glue traps. I have to date trapped well over 100 confirmed brown recluses so who knows how many I have.I have read that spraying for them is not only ineffective, but also counter productive, which makes me wonder why these products are different. Other places have posted that spraying kills other insects, which recluses like because they prefer their prey dead, and may actually cause a sort of dementia in recluses and cause them to be aggressive, so the spiders need to be sprayed directly.I am obsessed with eliminating these things.

  21. 21

    Hello. It is an unproven myth that getting rid of their food source will cause a type of dementia in brown recluse spiders. Actually, killing other insects with insect spray will simply get rid of their potential food sources. Also, there are products available that will kill brown recluses. I have called several different manufacturing companies that produce different liquid concentrates that will kill brown recluse spiders. Backed By Bayer has three different liquid concentrates that will kill the brown recluse including Suspend SC, Tempo, and Temprid SC . Also, Sygenta has a product that targets spiders including the brown recluse called Demon WP. All these products that are listed are the top products in the market right now for general pest control as well as spider control.

    Hi from Nashville…..What the heck…..all the sudden I have these little turds coming out of the woodwork……LITERALLY!!!! It’s August 24, 2011 and I know spiders are abundant in the Fall…..but all the sudden I am killing 3 or 4 a day…….HELP ME……I have brand new carpet and I don’t want to ruin it….I have 2 run across my bed…..RIGHT NEXT TO ME……..I screamed my dads ear on the phone…..(he’s wasn’t too pleasant for him either)…..I have always had BR’s but never this many or this big….it’s like they got into miracle grow….or viagra…..or both.

  23. 23

    Since the weather is a little out of hand and temperatures seem to be somewhat sporadic, it may have triggered a massive movement of all crawling insects including brown recluse spiders. I suggest spraying Suspend SC or Demon WP. Suspend is a liquid that you dilute with water and spray. It will dry on clear. Demon WP is a powder that you mix in water and spray. It has a longer residual time that Suspend but it will dry on with a visible, almost foggy, residue.

    Hi I live in Green bay Wisconsin. I was wondering if every home has brown recluse spiders in it. I am so afraid of spiders. Also how common are they in Wisconsin

  25. 25

    Hello Sheila, I don’t think all houses have brown recluse spiders. That’s like saying, all houses have black widows or all houses have centipedes and ants. Of course, any home can be a shelter for brown recluse spiders, you just have to make sure and be wise about doing regular outdoor treatment. If you are able to do a good outdoor thorough or barrier treatment, then there is no reason for them to even enter the home. Target all entry points as well as utility lines and make sure to seal all cracks and crevices.

  26. 26

    Hello, I live in Chile where brown recluses are unfortunately very common. I saw one in my closet the other night and it got away before I could kill it. I haven’t slept well since. I’ve been cleaning and spraying, but it hasn’t shown up again. Does the spray really not work? Is it the glue traps that I should try and find. Also, if I saw one does that generally mean there are more? Or are they often just found alone.

  27. 27

    Brown recluse spiders and many other spiders species are usually non-social which means, they will not live in large colonies like ants or roaches. Brown recluses receive their name mainly from their physical color as well as their reclusive behavior, hence, Brown Recluse, so I don’t think you have to worry about finding many more elsewhere. However, depending on the location of your home, you may have brown recluse spiders enter your home more frequently than you wish. Glue boards are by far the safest way of controlling brown recluse spiders, but sprays will work! Long residual sprays work to kill brown recluse spiders when they come in contact with the treated area and instant knock down agents that usually come in a pressurized aerosol form also work to kill brown recluse spiders on sight.

  28. 28

    We have brown recluse badly and when we first move in we thought they were coming from an old shed that we tore down, but years later we see them and black widows. I have a phobia of them and have 2 children and 1 on the way and want nothing more than to know everyone is safe. We have paid to have our home sprayed and it didn’t help. Last night I found a brown recluse with a sac of babies behind my bed. Please help!!!

  29. 29

    Hi Cindy. I’m very sorry for this ordeal. I myself am terrified of spiders! The best thing to do for brown recluse is to set traps in concentrated areas as well as use long residual sprays that are POWERFUL like Cykick CS. You want to make sure you spray the concentrated areas inside and do an entire perimeter treatment on the outside. You always want to make sure to spray entry points from the inside as well like door frames, windows, and any other cracks and crevices. Keep in mind that all treated areas must be left alone to dry before anyone comes in contact with that area again. If there is anything that you have more questions on, feel free to contact us again and we’ll try to help you out the best way we can! Good Luck!

    In a few weeks I will be cleaning out a storage shed and I’m concerned about recluse spiders, is there a bug bomb that can be placed in the storage locker the night before to reduce the chance of an encounter

  31. 31

    Usually, bombs are not very effective for spider control because they must come in contact with the insecticide. There is the Speckoz Evercide Total Release Aerosol Fogger that is labeled to kill spiders. Aerosol sprays are also very effective. Cy-Kick Aerosol is a great product for spider control.

    Hi. I live in the country in southern Illinois and definitely have a decent number brown recluse spiders in my home. I’ve confirmed the spiders arecbrown recluses using the eye patternand the violin markings since the eye patterns are most distinctive and we have many different kinds of spiders where I live. I have a fair number of sticky traps out and feel pretty comfortable that the spiders have secluded themselves to my storage closet under my stairs and those that do wander out seem to be getting caught in the traps which although disgusting makes me feel better. I’ve lived here since August and have yet to be bit *knock on wood*

    My question is this: I’m planning to move in a few months and the “spider closet” is where I have stored my various sizes of cardboard boxes. Yes I realize spiders like cardboard but I stored them there before I realized I had brown recluses and I’ve been too scared to go into the closet to get rid of the boxes. I’m concerned that I may transport spiders from my house to my new location. If I work up the courage to remove the boxes from the closet, is there anyway to catch the spiders coming out and prevent any new ones from going in as I create, fill, and store these boxes???

    I’ve thought about surrounding the boxes with sticky traps but given that I probably will end up with 50-100 cardboard boxes packing up my place, sticky traps seem like inefficient and expensive method.

    Any suggestions?????

    Iv lived in a apartment complex in Kentucky for the past 7 months and have had a brown relcuse problem since day one. A pest control business came out and has sprayed and dusted about 5 times now and we are still seeing them. Could the infestation be so bad that the spray wont work? If it wont work, what should they do?

  34. 34

    You should definitely keep glue boards around in isolated areas where you are finding them. You should also check for cracks in the windows and door frame since it’s apartment complex. Also, make sure that the pest control service is dusting the wall voids. Consider changing the insecticide as well.

  35. 35

    I woke up to use the bath room and i saw something and all the lights was off so i couldn’t see very well but i could give the color out a little it was a brown or black or gray i not sure but it was in the litter box and it move so i mostly ran so i dont disturb it so i don’t get bite and i don’t know what to do so please tell me and i do have bug spray but it was that bathroom with the spider and i been getting these kind of insects

  36. 36

    We have lived in our somewhat rural home for almost 9 years now, and have tried to deal with the snakes, bugs,spiders (including recluse) and animals around in stride. But more recently we have been seeing an increase in the number of Recluse spiders we see. Still only one or two at most per week, but in the past we have seen only one or two per month. I would like to control it before it goes any further.

    I have read a couple of times online that baby powder and food grade diatomaceous earth help keep spiders and insects away and may possibly even kill spiders and insects. Most of the posts I have seen claiming this state that they have used it in conjunction with traps in areas where they felt using a pesticide could be detrimental from a health perspective. (babys rooms, around beds, near food and eating utensils, etc..)

    I can fully understand,and plan to use, pesticide sprays and powders in the obscure dark spaces of the inside of our home. Also long residual outdoor sprays. But it would be nice to have a safer option in the immediate areas of our beds and food prep areas. Is there any truth to the claims regarding the use of fine powders?

    I just moved to Mississippi from Texas. I am renting an old house in the country, surrounded by woods. I’ve been here 6 weeks, and saw the first Brown Recluse 3 days ago. Since then I have seen 15, and this is since pest control came and sprayed, and I also used Demon WP myself on all baseboards, closets and cracks and crevices. I am still seeing live ones. I am moving out. I have heard horror stories of how hard these are to get rid of and I will not sleep not knowing if they are ever gone. Is it really possible to completely rid an old country home completely of Brown Recluse spiders? And why am I seeing an abundance of them suddenly?

    Hi Alison,
    Unfortunately, brown recluse spiders are especially difficult to kill with just insecticide. Spiders usually die from insecticides as they clean themselves and ingest the poison. Brown recluses, on the other hand, do not clean themselves frequently and usually, the insecticides take a long period of time to become very effective. We have noticed that glue boards are the most effective method of kill for brown recluse spiders. I apologize that I wasn’t able to better help you.

    I live in central New York, and as far as Ive read, brown recluse dont usually live here, but Im pretty positive thats whats infesting my garage. I find them periodically in my house, but its obvious they are primarily in my garage. Im gauranteed to see atleast 3 EVERY time I go in there, which is often because my washer and dryer are in basement which I can only get to through the garage. What is your opinion on the pesticide, Terro? I used it today, but after reading this page, Im afraid its not going to do anything. The reviews had many people saying that Terro specifically helped with their brown recluse problem, thats why I bought it.
    Does anyone ever really get rid of a brown recluse infestation? Because this might be a deal-breaker for me… I am terrified and it genuinly ruins my day.

    Please help. I was bitten by what appears to have been a Brown Recluse about 3 weeks ago. I went to the hospital 3 days after noticing the blister looking wound. I was itching very bad. Now, after 3 weeks the wound is still open and has skin around it that is as hard as wood.This being said, I again work up this morning with a 3rd (in 3 weeks) itchy, burning red open blister.My landlord has had a exterminator out and then came over himself to try to resolve the issue. This is NOT working! What else can be done? This is becoming an expensive medical cost.

  41. 41

    We have lived in Jackson, TN for almost six years now and have been dealing with the Brown Recluse all along. They are especially bad here, the first year was a nightmare, they were everywhere! Once we started renovations, and keep the place clean and uncluttered, we have seen less and less but have never gotten rid of them completely. We take all precautions, especially removing dust ruffles from the beds, and getting all new bedspreads that don’t go near the floor. We keep the house covered in traps from April to October, we have never caught any in the winter. I hate them and we’d move if we could. Here they don’t ever climb up walls or hang from webs, or I’d have died of a heart attack.

  42. 42

    Hi Kay,
    Yeah, Brown Recluse spiders can really be horrifying, especially for people like me who have a terrible fear of spiders. Unfortunately though, they are not as easily effected by insecticides like other spiders are. You are doing well by setting up traps (glue traps I suppose) around the house as well as keeping clutter to a minimum. It You should check around the perimeter to do some structural control by inspecting for potential entry points. This may mean you have to fix some cracks and crevices by windows and doors as well as checking utility lines that enter the structure. Sounds like you have everything else under control though! Good Luck!

  43. 43

    Hi Wendy,
    Once bitten by a Brown Recluse, it can cause a variety of different reactions and we recommend that you continue to get medically treated for the spider bite. Unfortunately though, there are not many insecticides that will work effectively against brown recluse spiders. You may be able to use a fast knock down spray like Cy-Kick Aerosol to spray the spider on contact. We also recommend laying out insect glue traps all around your home, especially in suspected areas of infestation. You should definitely keep clutter and stacked boxes to a minimum.

  44. 44

    Hi Danielle,

    Actually, the only Terro product I am aware of is Terro PCO for ants…? Unless there’s another that you are referring to? Also, another piece of bad news…to our understanding, brown recluse spiders are not very effected by insecticides as easily as other species of spiders. Products like Suspend SC or Cy-Kick CS may slow them down and will eventually kill them, but the kill rate is very slow. We do recommend that you still carefully spray. More than spray though, we recommend the use of insect trapping glue boards. This will efficiently trap them when they are placed in suspected areas of infestation. I hope that helped you! :D

  45. 45

    Hi William,
    The best thing to do with brown recluse spiders is to kill them on contact. Moreover, you must get rid of clutter and make sure that you set up insect glue traps. Unfortunately, there are not many residual sprays that kill brown recluse spiders as quickly as other spider species. Glue traps are the best way to get rid of them as well as contact kill spray like Nisus Fireback Spider & Scorpion Jet Spray.

  46. 46

    Hi Mike,
    For spiders especially, dusts are effective only if their bodies come in contact with the dust. However, it is difficult to say that dusts really work for spiders because of the way they move. Since spiders have long legs and their bodies do not rest or touch the ground during movement, there are not a lot of opportunities for the dust to really have effect on spiders. The best tool to use for brown recluse spider control are glue boards. By setting glue boards in areas that are suspect for infestation, you are able to trap brown recluse spiders easily. If you have any other questions, feel free to contact us again! :)

  47. 47

    Hello Tammy,

    Honestly, I’m not sure why they are coming out all of a sudden. It could be a variety of reasons including the weather or even the insecticide that was sprayed. Unfortunately, residual sprays do not kill brown recluse spiders nearly as quickly as they should and the only real way you can keep monitoring for them or kill them is to use trap them using glue boards. Residual sprays will slow them down though, so we do recommend using Suspend SC or Cy-kick CS and keeping those monitoring insect glue traps out no matter the season.

    I found a brown recluse in my closet in my shirt and jeans. What is the best thing to do? i seriously hate spiders. I have 2 cats and one about got bit. I want to get rid of them for good and not worry about them comming back. PLEASE help me!! :) thanks

    Do brown Recluse Spiders live in Wisconsin

  50. 50

    Hi Casey,

    The only product we carry that actually have brown recluse spiders on the label is Zenprox EC. This can be used on baseboards and in the closets. You must always allow the product to completely dry before coming in contact with that treated area again. We also recommend glue boards to monitor and trap brown recluses. Any of the insect glue boards we carry will work.

  51. 51

    Hi Stella,

    Although there are definitely areas that are more concentrated with the brown recluse species of spider, they CAN be found in Wisconsin. Usually though, they will be most commonly found in mid-south region.

  52. 52

    I got bit by one of these little basta**s and yes its an amazingly mind blowing amount of pain…I’ve killed 2 more in my garage since. I’m on my second round of antibiotics that make me feel like hell at the time of the dose. I’m considering buying a snake or 4, letting them loose in my garage & sealing it off. In 2 months just call animal control to remove the snakes…HAHA!!
    Scott in KCMO

  53. 53

    Hi Scotty,
    I’m not sure how well the snakes will work. We recommend using glue traps to trap the brown recluses. We also have a product called Zenprox that is the only product we carry that is labeled for use against Brown Recluse Spiders.

  54. 54

    I live the the back woods of Tennessee. I am renting an apartment that is infested with brown recluse. It has gotten to bad for me to stay, so I am moving out. My fear is that they will hichhike with me in my couches and dressers. How do I make sure they don’t come along with me to my new house?

  55. 55

    Hello Karessa,
    Unfortunately, there is no sure way to make sure they aren’t hitchhiking other than manual inspection. You can spray furniture frames and your home with a product called Zenprox. It is the only labeled product that we carry for brown recluses. However, even Zenprox cannot be sprayed over every surface because not only is it oil based and can cause staining, but it is not labeled for use on the cushions or mattresses. I apologize that I wasn’t able to help as much. If you have any other questions though, feel free to contact us again.

  56. 56

    Hello, I just found a brown recluse in my apartment. When I was shaking things out a little while later, I saw some kind of smaller critter, either a baby spider or a tick run across my bed. I did kill it but was unable to really inspect it. How likely is it that my house is infested with these buggers?

  57. 57

    Hi April,
    The brown recluse and the other pest that you saw may be different pests. Depending on your surroundings, you could just have an occasional invader or an infestation. Since we don’t know the identification of that second pest, we are unable to differentiate between whether or not you have an infestation. We advise that you have an inspection done by a professional so that they can determine whether or not you have to do treatment to eradicate an infestation or not.

  58. 58

    Hi– we are living in a rental house in St. Louis and have a brown recluse problem (caught one and had it confirmed). We had the exterminators out but my concern is the same as many other posters– that we’re going to take them with us when we move! I’m not sure how we could manually inspect things like the undersides of sofas, etc. Is there anything else that can work? E.g. lock our belongings in a storage unit for a period time, leave them out in freezing temperatures, etc? Thank you!

  59. 59

    Hi Lisa,
    Yeah, unfortunately, there is no real way to prevent the brown recluses from being transferred except to treat your furniture. The only product we have right now that is labeled for brown recluse spiders is Zenprox. It is a concentrate insecticide that is diluted with water and sprayed. You would have to treat the frames of the couch and frames of furniture but you cannot actually treat the parts of the furniture that come in contact with people on a regular basis like on the cushions or mattresses. If you have any further questions or comments, please feel free to contact us again.

    Hi, I just wanted to respond to people living in Missouri with the Brown Recluse spider. Brown Recluse spiders are very common in Missouri and live where ever boards or rocks or any flat item provides a dry hiding spot. I find them in the barn just lifting a bale of straw, between the panels of tin on the walls or stacked extras, and in anything that has not been moved in a day or two. I have used sticky traps and sprays, all of which work but do not keep the spiders at bay due to the numbers outside ready to inhabit the indoors. I rarely find small ones as they are canables and eat their own. They love the heat but they do get thirsty and this is where my war on them works best. I have a garden tub in my upstairs bathroom where the AC does not do much cooling. In the summer it is always full of spiders. They are ALWAYS Brown Recluse. I have more spiders get caught in that tub than on any sticky trap. They get in and can’t get out. So, I always run a little water before going to bed and sure enough in the morning I will have trapped 4 to 5 spiders. They are in my attic I am sure, and since I have a lathe and plaster older home, I am sure they are in the walls. I have lived here for over 15 years and never been bitten, but I stay aware and careful, never pick up a trash can that has sat for any length of time without gloves or banging it on the floor first and never reach into a box or bag that has been sitting. I have had some close calls, waking to find one crawling on my husbands sleeping face, and when my son was 2 he was down for a nap and something told me to check on him. Good thing, I walked into his room just in time to see a huge Recluse climbing across his bare leg and headed to the gap in his diaper. I thank God he did not reach down to scratch at it. It gives me shivers to this day to think about it and he is now 30. They are scary, nasty critters in such numbers that fighting them is all one can do. You cannot rid yourself of them, only keep their numbers down to increase your odds of keeping them in the most hidden spots so you don’t come accross them, or they don’t come across you. But do leave a little dampness in the bathtub or sink at ngiht and when they get trapped in it, just run hot water on them and dead and down the drain they go. Move furniture and boxes and trash cans around as much as is reasonably possible, don’t stack things outside unless away from the house, and always check before reaching into a bag or can or box that has been sitting for any length of time. NEVER EVER take a picture off a wall without gloves or standing below it so one can fall down your sleeve. They love to get behind pictures and bookshelves. Those aren’t dust bunnies behind those pictures they are Recluse webs. Hope some of this helps.

    i live in missouri and have been bit twice,(almost 6 years ago, the second time was almost a year to the day of the first bite, both in the same house, both in sept.) We have since moved. The first time the spider was in my pants that had been hanging up in my closet! It burned al day that day and then by mid afternoon I started getting flu symptoms. I went to the doc and i ended up having to have surgery so they could remove all the dead tissue from the bite. The bite was a dime size bite and the scar from the staples go frm my back to my stomach!!! That’s how much tissue it had destroyed!!!! The second time I got bit, I had fallen asleep in my living room floor, I woke to my eye lid on fire!!! I knew right away what had happened. I went one of our local hospitals and they acted like they did not beleive me. After waitng what seem to be forever they finally got me back to a room. In the room I went to the sink to get my rag wet again and the brown recluse was still in my hair and had fallen off on to the counter. The doc and the nurse both seen it. So they had no choice but to beleive me!!! So i left there with 3 prescriptions, not knowing what they were or did I have anything explained to me!!!!!! After I got home my friend took my scripts to the pharmacy and when he got back I told him I did not know what I had taking and that I felt really, really weird. He then explained to me that I had not taking anything and that one of the scripts was a shot!!!! I have never given myself a shot and had no idea what to do. Later found out it was an epipen!!!! Needless to say THANK THE LORD JESUS, my friend was smart enough to know something was not right and took me to our other hospital!!!!!!! Or I probably would not be alive today!!! I do not remember going in to that hospital. I woke up a week later with breathing tube down my throat and eyes swollen shut!!!! I remembered getting bit and I could only write on paper. My first question was “am i blind?” I was not blind, however my eyes were still swollen shut. My own mother did not know who I was when she got to the hospital. I am a white woman around 140 lbs, when I got to the hospital everybody thought I was a 300 lb hispanic woman. I ended up being in the hospital for 2 weeks and when I was released the doc told me to carry epipens with me everywhere i go and that I needed to consider moving out of this area and that next time I get bit I probably will not make it and that the epipen will possibly not work. Well now I have no insurance now so I am unable to purchase them due to the cost!!! I am now living in a town house and found one in my bed!!!! The landlord had my place sprayed and I asked would they put down glue traps due to I was told spray did not kill them. She acted like I was a crazy person and did not know what I was talking about. They did put down traps and the one behind my couch has 8 on it, the 2 in my garage have 4 a piece on them, and there are 2 behind my bed, the one on my side has a huge one on it with a baby and the one on the other side has none!!! I also killed one crawling up my kitchen wall 2 days ago and it was a huge one as well!!! Even though they are usually pretty small I have killed 3 BIG ONES!! I already suffer from depression and anxiety so you can only imagine what I am going through!!! All I hear is the doc telling me next time I probably will not make it. I am now worrying about what is going to happen to my kids if something did happen to me!!!! Do you suggest me moving and also I want to know should I leave the traps down that already have them on there or put new ones down? I was not sure if having them on there would attract more or discourage them away from the traps?!?!?! I AM SCARED OUT OF MY MIND!!!! Thank you for taking the time to read this!

    Hey Sunny,
    I read through this whole board and I noticed that at first you were recommending sprays like Suspend SC and Demon WP and you said that they were effective against brown recluses, then you switched to endorsing Cykick CS. But eventually you decided that “glue boards are the most effective method of kill for brown recluse spiders.” Should I spend my money and time on the spray, or should I just use the sticky traps? Do you have any statistics on my likelihood of eradicating the spiders, or should I just move? I live in an apartment in Nashville TN and the brown recluses are concentrated in my master bath and closet. I hate moving, but if it’s my only hope I will do so. I am willing to do what it takes, but I want to know if I have a chance of fixing this problem.
    I hate to sound so negative, but I am completely freaked out. Thank you.

    I had sores on my hands after falling in a thorny bush – the sores were healing and my daugter complained about spiders in the lower level of our home. I purchased some spider spray called Terror but did not cover my arms etc.

    In a few days I noticed white webbing around my sores and I CAREFULLY hooked the — staple looking very thin hair out. Each sore had the same webbing. After removing the web there would be a + mark under each web. What happened to me??? Please HELP!!!!!

  65. 65

    Hi Kelsey,
    Unfortunately, there aren’t many bug killers that will have brown recluse spiders on the label. There is one product we have that you can have your parents apply. Of course, we do not recommend that you do the treatment yourself because it can be potentially harmful. If you have your parents give us a call at 1-800-788-4142, we can explain how the product is used and applied correctly. Looking forward to talking to your parents! :)

    Hi Caitlin,
    Insecticides and their labels are frequent to change. When we initially contacted manufacturers about brown recluse treatment, the standard answer and information that they gave was that unless it was specifically noted on the label that it did NOT kill a specific species, then the target is all species. For instance, on the label for both Demon WP and Suspend SC, it says “spiders” but doesn’t have a note that it will or will not kill brown recluse spiders or black widows, and so as stated from the manufacturer, we can assume that it will kill brown recluse spiders. But since brown recluses are almost like a different pest altogether in behavior from regular house spiders, we wanted to find the most effective method of treatment against brown recluses and we concluded that yes, although insecticides may delay them and eventually kill them, the glue boards will be the most effective. There is a new product that we carry though and it is called Zenprox EC. Zenprox EC actually has brown recluses labeled on the product label as a target pest and so we can trust that this product will be effective against brown recluse spiders. You may have read through the comments and may have already noticed that I have begun to promote Zenprox EC for brown recluse spiders and even black widows. Check out the label here:
    If you do have any other questions, feel free to give us a call at 1-800-788-4142 or you can even email us at and even continue to read our blogs here! :) Good Luck!

  67. 67

    Hi Helen,

    Unfortunately, this is something that we cannot help you with. You should definitely go to someone who will be able to take a look at the sores and better diagnose the problem for you. A dermatologist or a physician will be of much better assistance than we will be since we cannot determine whether or not it is from the bugs or if it is an infection from the cuts from the thorns. I apologize for being unable to help you.

    My wife and I just moved to mid-Tennessee from the Pittsburgh area a little over a year ago. Several years ago I watched a show called “infested” or something similar.

    There was an episode about a family infested with the brown recluse spider and I commented that “a little raid should have done the trick”.

    I couldn’t have been more wrong. Up north I never seen a cockroach let alone a brown recluse spider. Needless to say I got a HUGE reality check from the south!

    Anyway, I went to the local CO-OP and purchased a product called “ENFORCER HOME PEST CONTROL” in a gallon spray jug. It really seems to work! I wouldn’t recommend it if small pets or children are around. It does kill the visual brown recluses on contact!

    I am considering buying a house in the country in North TN. When we went to look at it I noticed 5 glue traps around the 4700 sq ft house and after inspecting them I confirmed that there were a total of 3 Brown recluse spiders in the house. It has sat vacant for a while and the glue traps were old with Dust on them but still very sticky. It is basically our dream house so I don’t want to discount it because of three spiders, but I’d like to get an idea of just how bad the problem may be. It looks from your comments that it is possible to be agressive and control the population with the proper products. It appears that the spiders are on the top floor of the home.
    Could you take a guess about how populated the house may be?

  70. 70

    Hello April,

    That sounds so difficult to experience. We do recommend replacing old traps with new ones once every 2 months. Also, we have Zenprox that is labeled for brown recluse spiders that can be sprayed on a variety of surfaces and can be broadcast sprayed on carpet. All treated areas must be avoided until the treatment has completely dried. If you do decide to move from your home, we recommend a thorough inspection of boxed so that they are unable to be transferred from one location to another. Good Luck.

    I worked in a thrift store and brought home alot of “stuff” in boxes that came from who-knows-where. Well….our home became infested with brown recluses. A co-worker and I became experts on these spiders, to the point of considering getting our pesticide licenses because here in Missouri we can’t buy the “good stuff” otc. Ultimately we discovered, as everyone here is being told, the answer to getting rid of this species is the baited glue trap, my favorite being the CatchMaster 288i. The University of Kansas has stated they use them, so that says alot. We bought 2 cases for our home & the result was nightmarish….to think this many were lurking in our home! I am adamant about using these traps! I have also noticed they like the sinks/drains and am going to do the standing water thing suggested by Debbie. I caught 5 in the rarely-used bathroom just this week…..and they are always in that clawfoot tub!! As for the thrift store…heh heh….the traps were black with spiders every time we checked! Otherwise, it’s quite entertaining with your cat gets one stuck on it’s nosy paw!!

    Ok so today we found a brown recluse in the bathroom of are home we live in Missouri and i have read so do alot of others who have posted im scared as i have a 9 month old baby and im 7 weeks pregnant as well..i have been going crazy reading and though i feel better knowing that not all brown recluse bits are bad my baby being bit scares me very much….we have lived here 6 years and have never seen one now we have seen 2 in a week not sure whats going on

  73. 73

    We have a brown recluse problem since moving into our new home. I researched that there are a few different Dusts that can help, but the Delta Dust sounds most promising to me, I just wanted to ask if I should just get the Delta Dust or any of the others (Drione) as well. Well calling the exterminators, they told me that they only spray, which I feel isn’t good enough, but I think I might have them spray also in conjunction of getting my own delta dust. Any suggestions?

  74. 74

    Ok, you will all think that I am crazy but the best way to combat the brown recluse & other insects is by getting some house gecko’s. That’s right, lizards. I had a friend tell me about them because I had so many spiders. I actually had one crawling on my neck because I put a sweatshirt on that had been in the basement for a while. Talk about being freaked out! I ordered 10 “house geckos”. I turned them lose in the basement and never saw them again. The best part is that they ate the spiders. I had not seen anymore spiders in 2 years. The gecko’s died in the winter.
    That is why they call them “house gecko’s” because people used them to get rid of insects.
    It makes sense. It’s a choice, do you want spiders that will poison you or lizards that eat the poison spiders. I’LL TAKE THE LIZARDS!
    As I said, I never even saw them again! You won’t even know they are there, they go into hiding right where your spiders are. And the lizards are very friendly and don’t bite.

  75. 75

    Hi Toni,

    We won’t be able to accurately describe how infested your home may be. Like you said, it is possible to protect your home from them if you are aggressive with the infestation. This will mean that you will need to use glue boards as well as an insecticide. We recommend using Zenprox EC, which is labeled for a broad spectrum spray even inside the house. This means you will be able to apply this product along the baseboards as well as your carpet area or even on hardwood. We do not recommend that you treat entire pieces of furniture, however, you can treat the frame of the furniture. We also recommend laying out glue boards. When you lay out glue boards for brown recluse spiders, you will have to lay out more than you think. It may take several glue boards per room. You may have to even put several glue boards under each piece of furniture and in the corners of the room. You should follow all product labels before applying any pesticide.

  76. 76

    Hi Sandy,

    House geckos are named so because they are often seen outside of homes, crawling on the walls, often times looking for food. It is true that they eat spiders, but I don’t really know if I have ever heard of them being released in the home to get rid of brown recluse spiders. Moreover, I don’t know how strong house geckos are against brown recluse spider venom. They also need heat as well as a hiding spot to regulate body temperature, so I also don’t know how safe it is for the lizards to stay inside the house without an optimal environment.

  77. 77

    Hi Tammy,

    To our understanding, dusts will kill spiders on contact, even brown recluse spiders. However, although they may walk over the treated areas, it’s hard for the dust to actually cling onto the bodies of the spiders because of their long legs. It’s a theory and it makes much sense, but we are not very sure to be honest. House spiders, we assume, have shorter legs and larger bodies so it will probably work for them, but brown recluse spider have long legs and flatter bodies. We recommend glue boards (a lot of them) and also Zenprox EC. If you have any questions, feel free to call us at 1-800-788-4142.

    Um, today i was outside and my dog was trying to eat a spider that might be a brown recluse spider. I was afraid it might be poisonous so I did not bother it. Can i take a picture and send it to you? Im very concerned.

  79. 79

    Hi Christy,

    Absolutely. We can try to identify the spider for you. Please email the picture to
    Some tips when trying to send pictures is that you get one from the top that is not blurry and where it is under normal lighting so that we can take a good look at patterns and the color. Also, try to place a coin, like a quarter, so that we can have a rough estimate of size. You may also want to send different pictures from different angles. We’ll try to get back to you as soon as we can! :)

    Tonight I.found a Brown Recluse crawling into the living room from the bathroom. My dad walked right over it! We have lived here for 23 years. I have never seen a recluse in here before. We mostly kill scorpions. What is the likelyhood that this is an isolated incident? We live in San Antonio, Texas.

    I’m sleeping with the light on tonight because I am scared bigtime! That thing was as big as a quarter!

    Just rented a house recently in North Louisiana. An older brick home that had sat vacant during a remodeling period and I could tell that spiders were going to be an issue. In the last couple of weeks, I have killed 5 Brown Recluse spiders. Went and purchased on Monday 34 Glue Boards, 1- 12 oz can of insulating foam and I powersprayed 30 gallons of Bifenthrin around the perimeter, windows, doors, entry points, etc. Going on 6 days, haven’t seen any. *****Beware of Fireplaces and where water lines come through the wall**** make sure the covers are snug and sealed over the pipes and seal off the fireplace inside and out. I am going to need 1 more 12 oz can of foam, so most homes 2 cans would be the norm. The foam is messy, just let it dry and cure overnight and trimming and cleanup is alot easier with a utility blade. Been making a walkthrough kids rooms every night very late and need sleep but be willing to do a little bit every day to change what caused the problem. If you choose to consult a pest operator, I recommend going with an experienced smaller company that can provide 3-4 references in spider control. Most operators can provide you 3 contacts. The larger companies are filled with inexperienced technicians that are overloaded with too many accounts and will refuse to spend the time needed to solve the problem. God bless.

    Hi Brenda,

    Unfortunately, I won’t be able to give you a solid answer on if this was an isolated incident or not. Normally, brown recluse spiders are found in boxes or undisturbed areas and are non-social. However, this year, there have been cases of “swarming”, where homeowners have found them at least once or twice a week in their home and may even catch several on just one glue trap. We do have one insecticide that can be applied both indoors and outdoors that is actually labeled for brown recluse spiders. Zenprox EC is also the only spray of its kind that is labeled for indoor broadcast spraying on carpets. Along with spraying, you should also set out glue traps in and around cracks and underneath furniture. More than one should be set out per room and even per corner in the each room. We recommend Catchmaster Mouse and Insect traps or Trapper Monitor and Insect Traps. If you have any questions, feel free to let us know.

    Hi Mike,
    Thanks for the input. It sounds like you’re taking all the right steps. We recommend using Zenprox EC instead of the Bifenthrin active ingredient. Bifenthrin will most likely kill spiders, but honestly, we are unsure if they are effective against Brown Recluse spiders. Zenprox EC though has brown recluse spiders on the label as a target pest. Everything else sounds good too, especially the use of glue boards.

    We started finding brown recluses about a month ago, in June, all of a sudden. Never had them before then! I live in Kansas, and the weather has been atleast 105˚F or above for the past couple weeks. Wonder if that has anything to do with it. We placed some moth balls outside, I’m wondering if that’ll do anything. I also see a lot of silverfish; are they luring the recluses in? We’ve had silverfish for a while but never brown recluses until now! I’m packing up to move out for college and I’m scared that I’ll bring a couple brown recluses with me to the dorm. Do brown recluse bites affect dogs? Could a brown recluse even manage to bite into a furry dog? I found a baby brown recluse on my bed a few inches from where my dog was sleeping! Also, we placed spider traps but we hardly catch any spiders in them!! We do catch a brown recluse every so often, but more often than not, the spider traps go untouched (except in the basement where different types of spiders and silverfish get caught).

    Hi Jasmine,
    We do not believe moth balls will deter brown recluses and the silverfish may not necessarily attract them either. However, the rising temperatures may have triggered some discomfort and activity for the recluse spiders because normally, they prefer cool, dark, and undisturbed areas. Brown recluse bites definitely affect dogs and are even very dangerous for people as well as small animals. When placing traps for brown recluses, you will need to use many more than you would think. We recommend placing multiple traps per location. The only labeled product that we carry for Brown Recluse Spiders is Zenprox EC, the concentrate insecticide that must be diluted in water. Please read all product labels before applying any insecticide. If you have any questions about the insecticide or traps, feel free to contact us.

    Hey, i just saw a huge dark brown spider running around my kitchen with the lights off, i noticed something moving on the ground so i clicked on the light and saw dark brown spider on the ground. When i moved toward the spider it took off under the refidgerator. I know they are active at night and like dark calm places, do you think this could have been a brown recluse?

  87. 87

    Hi Joe,
    Unfortunately, a lot of spiders portray this behavior and so it’s difficult to say if it was a brown recluse or not. You should set out glue traps around the inside of the house in a variety of areas so that you can try to catch the spider. By catching the spider on the glue trap, you will be able to better identify the spider. If you are able to identify the spider, we will be able to better assist you towards insecticides that will help you control the spiders in and around your house.

    I have a very active baby (20 months old) and I am very worry because I could n´t kill a huge brown recluse at his bedroom… someone told me to use Phantom because of my baby. What do you think?

  89. 89

    Hi. I think I found a brown recluse in my daughters room. I killed it but I looked pictutes up and it looks pretty darn close! Can you help me identify it so I know if we should take further actions.
    Thanks! Amber

    We lived in our home for 8 years before we saw our first brown recluse. It was on the lampshade next to the bed, just watching us sleep. I decided to purchase some sticky traps just to see if we had any more, since our house is in the woods, and in Missouri, which is the state with the highest concentration of brown recluse. Since 2007, we have caught 384 brown recluse in the traps. We have approximately 120 traps down all the time, and I inspect the traps every 6 months. I just checked them today, and we had the most we have had since we started putting down the traps. There were 100 spiders in the traps! One trap had 9 spiders alone. It is not necessary to replace the traps every time, you just need to scrape off the dead spiders occasionally, and when the trap gets quite a bit of dust on it, it is time to replace it with a new one. Not sure about the webs that other people are finding, since brown recluse do not make webs. They walk around looking for insects at night, and they do prefer dead insects. So, good luck with spraying for them. They will just hide, and come out later to eat all of the dead insects that you have supplied them with. As far as the post that says they are loners, that is also untrue. I have found nests of them living together out in a woodpile of damp rotten wood, and there were hundreds of them all together. For those that are seeing several of them in your house, most likely they are in the walls multiplying, where you can’t see them. We have not been bitten in the 14 years that we have lived in this home, and we intend to keep the sticky traps down for as long as we live here. They seem to help control them, just make sure to put them along the walls of the room, and behind furniture along the walls. Brown recluse like to travel around the outside perimeter, so that is where you will catch them. Good luck to all!

    Hi Ana,
    I’m not sure if you should use Phantom BECAUSE of your baby, but Phantom is labeled for even black widow spiders. We recommend Zenprox EC though because that is the product that actually has brown recluse spiders on the label. Make sure that all treated areas are completely dry before reentry by anyone, including your baby. We also recommend setting up glue boards all around the home, under furniture and in corners. I hope that helped! :)

    Hi Amber,
    Pictures are usually unidentifiable. We recommend taking a sample to a local pest control supply store or a professional pest control technician. We also recommend visiting local entomologists at a university near you that specialize in studying insects so that they can help you identify it. If you have any further questions or comments, please feel free to contact us again.

    I live in an old farmhouse that was vacant for nearly seven years, in the middle of the woods in S. Ill. Before I moved in (a year later), I had the house dusted with silica gel a few times & had sticky traps everywhere. This really reduced the population as before it was loaded with recluses.The house was then remodeled, new drywall in all rooms and basement has B-Dry system installed. The bad windows replaced. After I moved in, the first year I saw one run across the floor from an old dresser that had been in the house, so I got rid of that dresser. I didnt see anymore until 3 years later(summer 2012).I saw 5 in a week and a 1/2. I still did not spray, but got sticky traps for all rooms. Never caught any recluses, except a few water bugs in the basement.But before I purchsed the sticky traps, this is what I did, and hope it will help alot of people. BTW,I have not seen any spiders at all since., though I am considering an outside perimeter spray to reduce any bug species. In every room I srarted with the outlets & switches, I pulled off every cover & installed insulation covers. Before this I caulked any gap between the outlet box & wall.After I installed the insulation pad, I sealed that with a thin perimeter of caulk.Let the caulk dry & put the outlet cover back on. I then checked all trim in the house and applied caulk around windows, baseboards, door trim. I then bought screen material, cut it to size, put screen in all my ductwork registers and secured screen with aluminum furnace tape. I cut screening to size and put that in my bathroom ceiling fan attached with white duct tape on the ceiling, then put fan cover back on. Sure hopes this someone. Also I read awhile back on a site, that they are shy spiders, that one can literally live in a house infested with them & never get bit. Also, that the males have less venom. Males do the most wandering and people are most likely to be bit by a male. Thankyou for reading

    Hi Eileen,
    Thanks for the great advice! I hope you tune in more often!!

    I just had my chimney cleaned and the cleaner said that Brown Recluse spiders like to live in them…he found webs, but said he did not see spiders. However, I found a HUGE spider that my husband believes is a BR near the front door the day after the chimney was cleaned…coincidence? I have never seen them in the house before. We have an unused fireplace in our bedroom and now I am freaked out that they could be in there…can I set off a bug bomb inside the unused fireplace (it is not gas) and hope that will help to get rid of them? I have put out glue traps but of course not I am afraid to look at them…I am going to begin a cleaning of the basement too and follow all the other advice for treating the perimeter of the house and checking the closet, moving the bed away from the wall etc. I hope using a bug bomb in the fireplace will be a good start…any thoughts on that? Thank You.

  96. 96

    Hello Katy Wilson,

    We do not recommend using the bug bomb. Not only is it ineffective, but it is also potentially very dangerous to use in a space like that even though the fireplace is not used. Continue to use the glue traps around the fireplace and a residual insecticide like Zenprox EC around the base of the fireplace and in undisturbed areas and corners of the rooms. If you have any further questions or comments, please feel free to contact us again.

    I got bit in bed last summer and up until that time had not realized we had any problem with spiders in our house (it was a brown recluse). Since that time, I have had traps out and caught many, have had exterminators’s out.. I was pretty freaked out, I have always Hated Spiders!! Anyway since that time I have had three episodes with spiders in bed at night…Our house is fairly new, my bedroom is clean and not at all cluttered, and I usually take a bath before bed too… are spiders ever attracked to people or a scent I could have without knowing it, like the lotion I use? I would like to be able to sleep in peace again!

  100. 100

    Hi Sharon,
    I don’t think they are attracted to your lotion or fragrance scent. Monitoring and keeping track of them by setting out traps is the best way to control for brown recluse spiders. If you have any further questions or comments, please feel free to contact us again.

    I just moved to Kansas in a brand new apartment and I keep finding spiders. Im assuming they’ve been having a grand time in the apartment before i got here, because i waited two months after it was built to move in. Part of the problem is the poor insulation under the doors — just now I (luckily) caught a spider walking into my home. I don’t know specifically what kind of spiders I’m dealing with (you’d be crazy if you think I would get close up to them), but any suggestions (specifically treatments, sprays, bombs, NUKES, whatever you would suggest would be wonderful.

  102. 102

    Hi Ali,

    I do recommend contacting maintenance to not only start a pest control program for your apartment, but to also get the insulation fixed under the doors so that you can eliminate one of the main entry points. Indoors, you can always use an instant knockdown spray like Cy-Kick or 565 Plus XLO to kill the spiders on sight. If you have any further questions or comments, please feel free to contact us again.

    I live in Missouri and have lived in my house for 19 years, during this time I have never seen a brown recluse in my house. Over the last 24 hours I have killed two brown recluse spiders in my room. My room is usually cluttered, which I know I should fix that, but the only thing that has changed is that I bought a mini fridge at a garage sale. Could a brown recluse web be in the bottom or in the back of the mini fridge? I cleaned out the inside so I can only imagine it might be in the open back of it. I’m definitely buying sticky traps in the morning. If the spiders came from the fridge how fast could they spread throughout my home?

  104. 104

    Its very possible and likely that they could be coming from the back of the fridge. Using glue boards is a great idea. You will have to use a lot of glue boards for larger coverage area. The spiders may forage around for food, but will likely come back to its nesting area.

  106. 106

    Brown recluse do reside in areas of South Florida. Glue boards are one of the best ways to eradicate brown recluse problems. For indoors you can use a product called Zenprox EC, which is labeled specifically for brown recluse and indoor use. Once it has fully dried it is safe for the children or pets to reoccupy the area. Focus spraying around crack and crevices. These are likely areas in which they will reside because brown recluse spiders like secluded and undisturbed areas.

    This may sound insane but my neighbor saw and killed what she swears was a brown recluse walking on the water in my swimming pool. She said she also saw one in the skimmer box sitting atop a pool toy. Is that even possible? Would they be able to live in let alone walk across the water? Now I’m terrified to let my kids swim and I can’t find any information on recluses and water. Can you help please and thank you.

  108. 108

    Brown Recluse spiders don’t usually live in the water. Fishing spiders would actually be ones to likely infest the pool area. With out a picture its difficult to give you an exact answer of what the spider may be. However treating the perimeter of the pool area with a residual insecticide like Suspend SC will help control the insect population in that area which would also be the spiders food source.

    Hello! My renovation home has a brown recluse infestation. It has 4 fireplaces in it and they’re also living in the fireplaces. I have plans to have the home proprely treated, but I’m not sure what I can do to to get them out of the chimneys, does anyone have any advice?

  110. 110

    I would suggest that you light you fireplace so that all the bugs will by the smoke. However it is the middle of summertime, so it may not be the most appropriate approach during this time of year… Your other options would be to use glue boards to capture the brown recluse.

    Hello i just found a large spider with orange skinny legs. I saw it crawl have out of my shoe then back into it. I through the shoe outside and lost it. I live in Wisconsin what else could this be i cant sleep at all

  112. 112

    Hi Jr,

    Thanks for your post. It doesn’t sound like brown recluse spiders because they are shades of brown. However it does sound like it could have been a woodlouse spider.

  113. 113

    Which of these treatments for brown recluse are safe if you have small pets in the house?

  114. 114

    For Brown Recluse treatment we would recommend either Taurus or Zenprox EC. Zenprox EC is designed for indoor use only. The Taurus can be used both indoors and outdoors but the active ingredient contains a slight odor so you will need to thoroughly ventilate the air after application. Once product has fully dried, the area can be reoccupied. For Brown Recluse treatment it is necessary to treat undisturbed areas, cracks, and crevices.

  115. 115

    Hello yesterday I found a brown recluse crawling on my newborns bassinet, I killed it but what are the chances their are more around shuld I be worrieafter seeing one? will their bites kill a baby?, I live in a desert area in California.

  116. 116

    The recluse you saw crawling around was most likely a random forager foraging for food. Brown recluse spiders prefer to reside in undisturbed areas and are not likely to nest out in the open or near areas where frequent disturbances may occur. The male recluse spiders spend most of their days foraging around for food which appears to have been the case for your situation. The best way to get the recluse spiders to leave your area is to eliminate their food source which would be other insects that may be living in the area.
