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.

INSPECTION

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.

SAFETY EMERGENCY PROCEDURE

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.

CONTROL METHODS

Prevention:
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.

    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.

    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!!

    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.

    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?

  5. 5

    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.

    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?

  7. 7

    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.

    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!

  9. 9

    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!!!!!

    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: https://www.pestmall.com/PDF/Zenprox_EC_Specimen_Label.pdf
    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 info@pestmall.com and even continue to read our blogs here! 🙂 Good Luck!

    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?

    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

  23. 23

    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?

  24. 24

    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.

  25. 25

    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.

    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.

  27. 27

    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.
    Thanks,
    Christy

  29. 29

    Hi Christy,

    Absolutely. We can try to identify the spider for you. Please email the picture to info@pestmall.com
    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?

  37. 37

    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?

  39. 39

    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.

    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!

    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.
