How to Get Rid of Black Widow Spiders



Black widow spiders are known that the female black widow eats the male after they are done mating, which is only a belief. A female black widow spider is black with a red hourglass looking mark on her abdomen. The adult male black widow spiders are harmless. They are considerably smaller than the female size, about half the size and usually has yellow or red band with spots on their back. The legs are longer in proportion to his body than of female. The younger black widow spiders are primarily orange to white but will acquire more black as they get older.


Black widow spiders can be found around firewood piles, in trash, rubble piles, under or around houses and privies, sheds and garages. They can also be found under eaves, in storage bins, toilets and sheds, meter boxes, and other undisturbed places. The female black widow spider hardly leaves the web and can rebuild or change the web based on her needs. The black widow spider spends most of the time during the day on her web and most of the time, she will be hanging upside down.


A person might not always feel the black widow spider bite until later.

  1. The very first sign of a bite is a small swelling and might have two small red spots in the center of the swelling. After about 3 hours or later, the place where a person was bitten will become more painful.
  2. Common reactions are said when a black widow spider bites is an entire body ache especially in the legs.
  3. Other symptoms: alternating salivation, dry-mouth, and paralysis of the diaphragm, excess sweating can occur.
  4. The poison injected can cause abdominal pain similar to appendicitis as well as pain to the muscles and/or to the soles of the feet. Most of the symptoms disappear within 2-3 days.
  5. A person bitten should seek immediate medical help and get treated.

The black widow spider only bites when she is protecting her eggs and feels as if she is in danger as a defense mechanism, so if you find a spider, please do not touch it with bare hands or feet.



To help prevent a black widow spider from making a web in your home, you will need to remove all the places where they might hide. Everyone should always remember to wear gloves and not to walk outside barefoot whenever you are removing or cleaning out the places that they might live or hide. Also, remember to dust and vacuum around windows, corners of rooms, and under furniture. Also to trim weeds around the building and remove debris so the insects and black widow spiders will not be attracted to living on or in the house. Remember to makes sure that you seal openings and install screens and door sweeps to prevent black widow spider from moving indoors. If a black widow, webs, and eggs sacs are found, vacuum all of them and remember to DISPOSE the bag after each vacuum. Also, with regular pest control, it will reduce the number of insects in your home and in turn it will also reduce the chance of a black widow coming into your home.

Crack and Crevice Treatments:
This treatment is generally applied with a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap ),  dust (DELTA DUST), and aerosols ( CY-KICK 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  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.

Broadcast Treatments:
This treatment is generally used for large turf or other landscape areas and will contain directions for specific amounts of the product to be applied as a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap ) to a given area.

Broadcast treatments are usually for the entire lawn. For this treatment we suggest a 1 gallon sprayer for the application of liquid spray (CHAPIN 1 GALLON SPRAYER). Following the directions on the label, you would spray the entire lawn with the solution. Spray areas where there are lots of trees and bushes in the backyard making sure you have gotten every inch of the lawn where the spider might live.

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% CSFenvaStar EcoCap ).

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.

    I have found over a dozen southern black widows on my property in southern New Jersey in Septemeber 2010-present. We had an exterminator come and we were unable to find anymore in the next couple of weeks. I am now seeing male black widows again and I am afraid there are more than we thought. There have been various sightings throughout the neighborhood. I am having trouble finding any information on the southern black widows in New Jersey anywhere on the web. Is there anything we can do such as make the township aware of the increase in these species. What are some other ways to keep the population under control when the exterminator is not around. Ortho wasp spray seems to help kill them. Have you heard of any reports on southern black widows in NJ?

  2. 2


    Wow, I haven’t heard anything about black widows in NJ.
    The only things I’ve been hearing these days are bed bugs and stink bugs.
    If you’ve found the Ortho treatment effective, I would recommend still using the Ortho.
    Also, sometimes the spiders are known to hide inside shoes,
    and there have been cases when people got bit as they were putting their shoes on.
    I would just caution to watch out for that, and if the infestation seems as if it’ll grow,
    I’d recommend using either Suspend SC or Demon WP
    around the door and window frames, cracks & crevices, and in corners or where you’ve frequently spotted them.

    Hi Kim,
    I hope you are still monitoring this site. I am from South Jersy as well and just found a Black Widow on my property. I am having a hard time finding ANYTHING about BW’s in South Jersey and was wondering if you found anything out. Also wanted to see what town you lived in. I am from Gloucester County. Thank you!

  4. 4

    Hi Rob,
    We’re actually located in Atlanta, Georgia… quite a distance from South Jersey, haha. But there are chemicals that you can use to kill the black widows that are present and also to help prevent future ones from webbing near your area. I would probably recommend that you use an insecticide that comes in a wettable powder form. Although it leaves a visible powder like residue after it dries, it appears to be the most effective. Something like Demon WP or Cyper WP would be a good product to use for such case. Good luck!!

  5. 5

    Just found one in my bedroom. I live in Cumberland CO NJ. Are the recommended chemicals safe for babies I have a 7 month old. Scared!!!!!!

  6. 6

    Oh no!! Black widows are so scary. Too scary. But they are typically going to be non social insects. Even though the area you live in might have a common, it may not be as common to have black widows enter the home. There is a liquid concentrate insecticide called Suspend SC that you can use indoors and outdoors as a barrier treatment. However, I want you to keep in mind, that although its safe indoors, its only safe after it is dry. As long as it is dry, then it is safe for even your baby. Suspend SC targets spiders and has a residual for up to three months, so I think it’s going to be highly effective for you.

    I am living Colorado and renting a tri-plex and I am seeing all kinds of spider webs outside around the stucture. I have only lived in Co. for about a year and a half and I have already been biten by a brown recluse or the doctor said it could have been MIRSA anyway I was very sick for a couple of months and I still have the purple scars after a year and a half. I went to the local Walmat to get a pesticide to spray and all of them (all major name brands) said that either they could not kill black widows or brown recluses or that you had to spray on them directly to kill them. Well I really would like to prevent an encounter with them by either way so I would really like to know a product that I can use for this problem. Also, I have a little 4 pound dog (yorkie) that I need to protect from deadly spiders and pesticides. HELP!!!!

  8. 8

    Hi Char,

    For spider treatment a long residual insecticide is highly recommended. That way the pesticide will still be in that area to effect any spider that dares to web on the treated surface (: Demand cs is a micro encapsulated insecticide that can be used for spider treatment. Glue boards also work well for spider treatment. Since spiders like to create webs along corners of walls you can set up a glue trap along those areas to catch and monitor the activity of the spiders. Once the liquid insecticide dries fully it is safe to be around small children or pets so you should be okay with your yorkie

    i Live in Jackson New Jersey and cleaning out my wood pile today i found a female Black Widow saved it in a jar. full red hourglass under her and two red dots on the top side. should i kill this spide or let it go in te wild since they eat most annoying insects?

  10. 10

    I live in Northern Virginia. I saw my first Black Widow spider last year. Which I killed. Recently I saw two in my front yard, one was really large and the other was small. Are they common in this area?

  11. 11

    Hello Vinnie. Although black widows do predate on other insects, they are also harmful to people and small animals. It would be best to eradicate the infestation around your house especially if you have pets and small children. To assure you, there are other non-harmful spider species that will help you get rid of the insects.

  12. 12

    Hello, There are several different species of black widows and they can actually be found all over the United States. Unfortunately, they are commonly found everywhere and are just a species of spider that you have to be careful of. The best would be to practice exclusion which would be to use a micro-encapsulated or wet-able powder insecticide around the perimeter of your house to provide protection so that they do not enter your home.

  13. 13

    I live in a suburb north of Houston, Texas (The Woodlands). We moved into a new home in March and as of last night I have found 5 Black Widows within the past week in the corners of my garage. I have a years contract with a pest control company and they are coming out to spray again. I’ve lived in The Woodlands over twenty years, all three homes have been in the very same area but I’ve never had any problems until now. I’ve been told we probably have a nest somewhere and would love to find it. Any suggestions?

  14. 14

    Hi. I have found 3 black widows on my house within the past year. they are outside in the cracks of my walls. what should i do? are there more?

  15. 15

    Thankfully, black widows prefer to live in secluded areas, so they should be relatively easy to find. Think about any cluttered, unfrequented areas in your house and look there for signs of black widows. If you need to treat outdoors, first search for any sheltered areas inside bushes, near trees, etc to try to locate the spiders. I’m surprised your exterminators didn’t already do this for you! Remember, just check out any areas that are secluded and that you don’t come in contact with often. Don’t forget to wear protective clothing to be safe!

  16. 16

    Thankfully, it sounds like your infestation is relatively mild, since you’re not seeing 3 black widows a DAY or anything like that, haha! I don’t mean to alarm you, but there most likely are more black widows just hiding around somewhere in those cracks. I would recommend that you get a dust product (i.e. Delta dust) or a wettable powder (i.e. Demon WP or Cynoff WP) and apply that around and into the crack in the walls where you have seen the black widows. That should hopefully control their numbers a bit and give you a peace of mind!

  17. 17

    I lived in Sacramento. My house and my neighbors house are infected with blackwidow spider i could see them every where at night with flashlight, and today i found 1 in my clothes kinda scared me a little since i dont want to get bit by those i guess they came from the A.C wind hole to my house……so far 3 peoples got bit by black widow in my town. Is it a way to prevent them from coming to your house? i really need help.

  18. 18

    Hi Eric,

    Scary! I don’t blame you for being a little scared; I personally would have freaked out, haha! I think the best thing for you to do is to follow the details outlined in the “Barrier treatment” section of this post. You want to treat around your house to try to prevent the spiders from coming in! You may also choose to look into Orthene PCO Pellets. They smell absolutely disgusting, but from what I can tell, they work! As for indoor treatment, you can use the liquid pesticides you use to spray the outside of your house. Also make sure to clean your house frequently and organize any clutter! Remember, more clutter means more hiding places!

    Hi, I live in southern Virginia and have seen about 10 black widows, each have been killed immidently, luckly they have all been outside. I am horrified of any type of spider, and we have 2 three year old boys.. Is is common to see this many spiders outside? they seem to be hiding in the dark, one i know for sure was a female and had a nest, it was smooshed and we made sure we killed them all. What is the best thing to use to get rid of them, I have a cat and 2 boys, so i am looking for something to use outside around the doors and windows, i the cracks and wholes in the brick, and in our bacement where the children and cat never go… please help i am aboslutly horridied… also, if one of our children was to get bit, and we are unsure what bit them, how long would we have to get them to a hospital and get them treated?

  20. 20

    Hi Jessica,
    Well, that depends. What was the time frame in which you saw those black widows? If you’re seeing 10 a day, then that definitely will require immediate treatment, but if you’re seeing 10 a month, that’s not as immediate. You want to go ahead and clean out as much clutter out of your home as you can and also eliminate all sources of moisture around your home; this will eliminate shelter and water, making it harder for the black widow to survive near your home. In addition, you can use a liquid insecticide such as Suspend SC to apply a barrier treatment around your home. As for how long you would have to wait, I’m not 100% certain, but I think for adults you want to go to a hospital within 8 hours.

    I live in northern NJ (Bergen County) and spotted 3 female black widows in their webs in my garage this morning. I’m stocking HUGE bundles of wood and bags of vegetation to throw away weekly, so I can only imagine how many more spiders there may be in these piles!!!
    We bought and moved into this old house 2 weeks ago. The place had been vacant for months, and the property barely attended for years. The yard was a jungle, and we’re clearing it up slowly. We’ve got the vegetation at least mostly away from the foundation.
    I don’t know that I’m going to be opening my garage door ever again… ;) This cleanup had finally made me grow over my fear of common spiders, but coming face to face with these in your own house is a totally different experience.

  22. 22

    Hello! WOW that sounds really terrible. But we hope you get everything cleared and you know that if you have any pest problems, you can always give us a call or email us and we will try our best to help you! :)

    I just bought a new car and it was infested with brown widows. Now they are all around my house. I have sprayed Suspend a pest company sprayed there product and I am seeing some dead ones. I do not see them at night like I did the first and second night of my nightmare. Please tell me they will die. I really don’t see them on my car anymore other than empty egg sacs. Is there anything else I can do for my car or house. I swear I am about to have a nervous breakdown.

  24. 24

    Suspend is a great product for spider control. You can repeat treatments every 2-3 months with Suspend. They are not very social so you won’t see a continual infestation for very long. For inside the car however, there are no products that I know of that have car treatment labeled on the product label for spider control. Unfortunately, I won’t be able to recommend anything to you. I’m sorry. But the Suspend will work for your house and structure! So make sure to continue to apply the Suspend every 2-3 months with the right protective gear and also after following all dilution rates and directions on the product label.

  25. 25

    I sprayed 4 black widows with some raid for black widows and scorpians, and discovered a few small egg sacs. I sprayed them as well will it work, or do I need to go do something else to the egg sacs. I was planning on clearing the webs tomorrow along with the egg sacs. But I just want to get rid of the eggs safely. I live in Colorado, but I’m familiar with the black widow web. Thanks

  26. 26

    Raid does not have a residual and although it will kill the black widows on contact, it will not provide a killing effect after it is dry. Our liquid concentrate products or WP products that are listed for spider control actually have a residual. Its hard to target eggs of any insects because of the protective covering, but if you treat and area that you know has eggs around it, then once the eggs hatch and the nymphs come in contact with the area that has been treated with a residual insecticide, they will die. I hope that helped!

  27. 27

    We set up and decorated our Christmas tree yesterday. This morning, I found a black widow on it. Any thoughts on what to do?

  28. 28

    Hey Dee! You definitely need to get rid of the spider. Black widows are recluse spiders by nature and non-social. I don’t think it would be likely to have more than one spider there but you definitely want to get rid of the spider. Most insecticides are okay to spray directly onto the tree. You can use an instant knockdown spray or a residual spray and spray around and on the tree as well as any cracks or crevices, any restricted areas, and any other areas that the spider might hide in. Good luck!

    Hi, I live in Norfolk VA and I have been having a spider problom. About a week or so ago I was sitting on the couch with my 3 year old and saw a spider crawling on his arm so I sort of grabbed it and through it. After I got up I found that I had killed it. I took a good look at it and tried to look for it on the internet with no luck but what I realize now is it was a black widow or at least thats what I think. The spider wasn’t black but a light brown and had long legs and a small body, now I know thats not the typical description but it did have the hourglass. Am I wrong, could it be something else? I did however find a unquetionable black widow behind my couch, it was dead ( I saved it so the land lady and exterminator can see it). That section of my couch isn’t against any wall and my 4 year old was playing back there…. From the pictures i’ve seen of the webs I think I found where it may have come from but its not very dark and not damp at all but is right next to the shelves where the shoes are kept. Now i’m worried to put any of my shoes or boots on. I never realized that they are so small, I always thought the were much bigger, I’m originally from Montclair NJ and i’ve never seen one up there, even when I lived in flemington NJ but I did use to see wolf spiders alot.

  30. 30

    I live in NM and my shelf has lots of these black spiders with big bellus I’m scars for my kids can’t even play in back yard oh what do I do.

  31. 31

    Hello John, Unfortunately, we will not be able to identify the spider for you unless we are able to obtain a still image. However, spiders are fairly easy to get rid of. Firstly, concerning your shoes, you can vacuum them before you put them on to ensure that they are not inside. Vacuuming is also necessary in the corners of the room, both high and low. This is will ensure that you are getting rid of their webs, which basically provides as their “home”. Use Suspend SC or Demand CS to treat your home for spiders. After diluting the concentrates, spray the solution in areas like the baseboards of each room (especially cracks, crevices, and corners behind and under the furniture), the window sills, and door frames. You may also want to do use insecticide on the outside of your structure to keep the spiders from coming in. This can be applied in the garage and storage as well. Consider doing a perimeter treatment which will require you to spray all around the entire perimeter of the structure in bands that are 2-4 feet up from the base of the structure and 2-4 out on the ground from the base of the structure. You also want to cover the window frames, door frames, the garage door frame, and any other entry points, including the utility lines that enter the building. This will ALSO ensure that you are using the insecticide to eliminate the spiders’ food sources (crawling and flying insects) which can be a reason why they keep reappearing. If you have any questions about spider, please do not hesitate to contact us again! GLuck!

    Hello Mary,

For your backyard, you can use a granules like Demand G Granules in the yard. If you have any questions about spider control, please do not hesitate to contact us again! Hopefully, spiders will not keep you from playing in the yard with your children again! We want to help! So give us a call or contact us again if you have any questions :)

    I live in Co.Springs. This last summer I hired a company to come out and spray my house as they found 13 black widows in the window well of my daughters room, 7 in my sons and 8 in the living room window wells. So I obviously have a serious outbreak of black widows. They have been spraying and removing the eggs and webs for the past 9 mo. and they keep returning. WHAT THE HECK DO I DO????? The company has a good rep. It is called Home Sheild pest control but obviously what they are using the black widows here are immune to. So now what do I do?

  34. 34

    Hi Jess, I’m so sorry to hear that! It sounds very stressful. To better assist you, I would need an idea of what the pest control company is applying. There are great products that will target black widows, but it is best to use a microencapsulated insecticide so that you have a longer residual effect with one application. Some of these products are Demand CS, CY-Kick CS, Lambdastar 9.7 and Fenvastar EcoCap. You should also consider using glue boards in corners of the home and in isolated areas of the home that black widows can be found.

    One of the reasons why the black widows keep returning may be because there is a valid food source for them. This means that you have other insects that will act as a food source for them. Regular pest control that is done consistently may be required. Also, you should check for cracks and crevices in and around your home so that you can potentially block them from coming inside. We also suggest that you use the insecticide to create a barrier around the outside of the home. This means that you will spray the insecticide around the entire perimeter of your home. Spray 4-5 feet up from the base of the structure and also 4-5 feet out from the base of the structure. Also target window frames, door frames, and utility pipes that may enter your home.

    If you have any questions about black widow control or any of the products that were mentioned above, feel free to contact us via telephone at 1-800-788-4142 or email us at

    Hi, Thanks for all the excellent advice on eliminating black widows. I have not seen any in my house, but previous owners created a habitat for them using retaining wall pavers as a flower bed border. However they are not tightly fit, and leave the ideal place for widows to build their web and be undisturbed. I want to remove these pavers, but worry that eliminating this area will encourage them to move into the house where we have not seen any spiders. Will treatment prior to elimiating enviroment prevent them from moving into the house, or into the crawlspace? Also… are widows likely to move into attic spaces of the house? or warm dry locations? I also plan to treat the barn but have hay stored in the loft. I am worried to spray in an area that foodstuffs for livestock is stored. How likely are widows to be in the elevated, warm and dry loft? Once sprayed, is a 24 hour curing period sufficient to place hay and feed back in the area? Thanks!

    I live in cocoa Florida. I have three acres in a rural area. I found two black widow females in my garage and called Terminex. They killed the two in the garage and found another with eggs in the car port. I have buildings all around my property. After 6 months the infestation is so bad we literally cannot leave our house. I went out to my office and it is so heavily infested inside there isn’t a 6 inch place void of a widow.

    They have taken over so heavily they are 6 inches apart in the grass now.

    Does anyone know of a natural predator for the black widow? It’s not safe here anymore.

    Hi I live in Okc,Oklahoma and I found 12 Black Widows in 1 day and a couple of days later I found another 1 then a few more so in about a week we have found close to 30 this is starting to drive me nuts I have kids that play out side and I have 2 small dogs what can I do I have tried a few things but still seeing them

  38. 38

    Hi Angie,
    Firstly, prior treatment will not necessarily prevent them from entering other spaces, but treatment will up the chances of killing them before they can enter other areas of the house. They are able to live in attics and other locations, especially undisturbed areas like the attics, closets, crawlspaces, and etc. Treating the barn will depend on if there are animals or not. Leaving the bard vacant for at least 1 day after treatment is fine, but all animals and foodstuff must be removed. If you have any further questions or comments, please feel free to contact us again! :)

    Hi Sam,

    We recommend Suspend SC as the acting residual insect killer for black widow spiders or Phantom Insecticide that actually has black widow spiders on the label. Since Phantom is a non-repellent, it cannot be detected by the insects that it targets. Actually, the cellar spider does prey on the redback spider, which is one of the species of the black widow. But there aren’t many natural predators of the black widow spiders.

  40. 40

    Hi Heidi,

    I’m so sorry to hear that, it sounds very stressful and terrifying! We recommend using Phantom Insecticide. Although MANY insecticides target spiders of many different species, Phantom is one of the few that actually have Black Widow Spiders on the label as a target pest. It is a non-repellent insecticide that the target insect pests cannot detect. We would like you to keep in mind that Phantom does not have an instant knockdown kill effect, but is slightly delayed. We recommend spraying this in all areas that are suspect to infestation. Always thoroughly read the product label before any application of the insecticide is done. Also, keep in mind that all treated areas must be avoided until the treated area is completely dry. If you have any further questions or comments, please feel free to contact us again.

    We live in Va and in the last month or more we have been seen more than 50 black widows.. My son is counting.. Theya re all over our yard and all around the outside of the house.. I have never seen so many before. what can we do to treat our yard as we have outdoor pets too…????

  42. 42

    Hi Frieda,
    That’s so wild! Black widows are unfortunately, not on many product labels as a target pest. The only product we have that specifically labels black widows is the Phantom Insecticide. However, Phantom has a delay kill effect and will not provide an instant knockdown. That is a product that we recommend though. If you have any further questions or comments, feel free to contact us again!

    Hi Chris,
    We don’t have many products that specifically label the black widows as a target pest on the product label. There are two that we know that specifically label the black widow spider. These two products are Zenprox EC and Phantom Insecticide. Both products are delay kill, but the Phantom is a non-repellent insecticide. All treated areas must be avoided until the treated area has completely dried. Don’t forget to read the label before application as well!

    I recently just moved to south carolina from Michigan. (In my vaulted ceiling Apartment which by the way is surrounded by trees) I Looked up at my vent to find huge black legs sticking out against the white painted walls. This spider was honestly probably about the size of a quarter If not bigger and all black. The body was small and the legs were longer than the body. I feel like it may of been a black widow spider but I couldn’t see the abdominal of it. Since it was on the vent in assuming that’s where it came in from since I just had pest control here. What can I do to get rid of these black widows?! I’m horrified of spiders to begin with and I don’t know if I can spray something around or in the vent when the airs off. Please help! Soooooooo creeped out

    Hi Lee,
    Unfortunately, there is no way to prevent them from appearing but you can use insecticides like Zenprox or Phantom to kill them. Although both have a slight delay kill effect, in the long run, it will prove beneficial. Those two are the known products we carry that actually have black widows on the product label. Keep in mind that when you apply these products, all treated areas must be avoided until it that area has completely dried.

    Hey Heather,
    Unfortunately, I won’t be able to identify the spider for you since I don’t have a clear description or a picture to really see what kind of spider it was. Hopefully, it wasn’t a black widow. Regardless, my assumption is that the spider was in or around the wall void or even on the outside perimeter. Sometimes, insecticides may have a repellent effect and so when you had pest control done, it may have pushed them to another location and the spider could have been triggered to move. The best spray for black widows that we recommend is Phantom insecticide in the concentrate form. This is a non-repellent and it is actually labeled for black widow spiders and of course, other spiders are targeted by Phantom. Unfortunately though, you cannot spray the vents whether they are on or off. This is because the insecticide has a residual and it can be potentially harmful. I hope that helped you and if you have any other questions or comments, feel free to contact us again :)

    I found a dead spider in my kitchen sink that heavily resembles a black widow. The abdomen was black with just a tink of a brown towards the top section that attaches to the thorax. On the bottom of its abdomen there was no red hour glass, but there were red dots in no paticular formation. Is this a black widow? I live in Northern Michigan and I thought these spiders did not live here?

    A product called “Bronco” E Equine Fly spray works 100% of the time.
    I keep several around, garage, barn, house, all ready to spray.
    It becomes an annual witch hunt. Every year you go out looking for them on warm days. One spray knocks their dick in the dirt. Then you just crush the eggs. They seem to hang outside their web with the eggs in the sunlight, early morning.
    These spiders give me the creeps. Discovered the product by accident. Used it to kill fleas on my chickens.

    Hi Mike,

    It’s hard to identify a pest with just the descriptions that you have given to us. You might be able to find some pictures online to compare it to. Although they might not be normal to find in certain areas of the country, that does not mean it is impossible to find them. You may want to apply some insecticide around the entire perimeter of the house. The insecticide that we recommend for black widows, as well as other spider species and even other common house pests like roaches and ants, is Phantom Insecticide in the concentrate form. It is one of the few insecticides that we carry that actually have black widows on the product label as a target pest. It is a non-repellent type of insecticide when it is used correctly and although it does deliver a slight delay in the kill effect, it is a widely used insecticide/termiticide by professionals and the spider will not be able to detect it because of the non-repellent feature of the insecticide. You want to create a barrier around the entire perimeter of the home as well as apply the insecticide inside the house as well on base boards, window frames and door frames. If you have any further questions or comments about the insecticide or black widow spider control, please feel free to contact us via telephone at 1-800-788-4142 or email us at

  52. 52

    Hi Geo,
    That’s not a product carry, but if it works for you!…We always advise that you read the product label before applying pesticides though and to make sure to follow the instructions so you can prevent potential safety hazards and health hazards.

    There two blackwidow eggs in my garage what should I do

  54. 54

    Hi Don,
    Black widow spider eggs can be easily removed by vacuuming them up and no insecticide is really necessary for black widow spider egg sacs. However, if you have an a black widow spider problem, it is best to do regular maintenance in and around your home. The product that we recommend is the Phantom Insecticide. Not only does it have black widow on the product label as a target pest, but it also includes a large variety of other common house pests like ants and roaches. Keep in mind that all treated areas must be avoided until the treatment has completely dried. If you have any further questions or comments, please feel free to call or email us.

  55. 55

    Is there a season when the black widows lay eggs so that we can hunt for egg sacs then? Or is it pretty much year-around? How often do they lay eggs?

  56. 56

    Hi Kathy,

    Black widows will primarily begin their mating during the springtime and eggs sacs are made during the summer months. If you have any questions, feel free to contact us again.

    I have had a serious infestation arise in my yard and now in my house. It all started with my daughter finding a hatched nest complete with their mother. We killed all of them with insecticide but now we are finding many of them daily, both outside and in my house. I found one this morning in the shower with me! It is out of hand and I have a professional pest control coming to spray. I live in a townhouse in central NJ and back up to the woods. What can I do to help get rid of them when their environment is literally in my back yard! I am deeply concerned for my two children and our cats. I have never heard of any being in NJ prior to finding these this last week. Is this unusual? Why are they here in such great number? Have they always been here in NJ? What else can I do to kill them off and protect my family? Thanks!

  58. 58

    Hi Robin,

    Yes, NJ has been home to northern black widows and you will be able to find that the state of New Jersey also is home to several different types of spiders, both venomous and non-venomous. There are several different kinds of products that we carry that has spiders on the product label but only a couple of them actually have black widow spiders on the product label as a target pest. The two products we carry are Phantom Insecticide and Zenprox EC. Both can be used inside and outside. They work a little bit differently but are the same kind of contact kill concentrate insecticide. Phantom has a delayed kill effect but is effective because it is a non-repellent type of insecticide that cannot be detected. It can be applied around the perimeter of the structure and indoors, it can be applied in cracks and crevices. Zenprox EC is labeled for broadcast application inside on carpets as well as cracks and crevices. It is not a non-repellent like Phantom but it will on contact. Both products specifically label black widow spiders on the product label as a target pest. If you have any further questions, feel free to contact us via telephone at 1-800-788-4142 or email us at

  59. 59

    Yes,I have dogs outside and I found over 100 black widows in their dog house,what should I do please help me i dont wont my dogs to die

  60. 60

    Hello Doc,
    With black widow adults, it’s the best to physically remove the live ones and then apply a residual insecticide that will kill them. You can physically remove them by vacuuming up the spiders and disposing the bag or by using an instant knockdown killing agent. The residual spray that we recommend is Phantom Insecticide, which actually has black widows on the product label as a target pest. The residual spray should be applied to all surfaces of the dog house, around the perimeter of the yard and around the perimeter of the house. Good luck, Doc!

  61. 61

    Help! I have been killing black widow spiders almost everyday in and around my house. I have even killed a couple that were brown but the same markings. I used Home Defense Ortho spray and they laughed at me! I got a stick and pulled the spiders, eggs, and web down and stomped on them. What can I use to kill them, keep them from coming back and where do I get this magic potion? I have pictures but I don’t know how to post them to make sure they are black and brown widows. Sunny help please!

    My boyfriend and I just recently moved into a rental house. We had a problem with our A/C and while it was being fixed my boyfriend went and checked the mail. When he opened the mail box he saw the biggest black widow he had ever seen. Of course, he killed it, got the mail and went on about our day. But long story short, EVERY time we go to check the mail, there is always another one… Yesterday I got off work and went to check the mail box, and this time there was a female about as big as a silver dollar and her egg which is so big that I thought it was fake… I just left her alone and now I’m afraid to even open the mailbox. I’m also afraid that our poor mail man may get bit so I put up a note warning him about the brooding family in the box… I have severe arachnophobia and I have no clue how to keep the spiders from coming back. Also, there is a huge dying bush that kinda grew around the mail box. Would that have something to do with it? PLEASE HELP!

  63. 63

    Hi Nicole,

    Unfortunately, there is no sure way of keeping them away or preventing them from entering your home. However, you can apply insecticide around the perimeter of the home to kill them on contact. We recommend Phantom Insecticide to spray around the perimeter of your home as well as alone the baseboards, window frames, and door frames in the inside of the house. Phantom Insecticide has a delay kill effect, however, it is a non-repellent and so it is undetectable to the pests. It is safe for re-entry after the treatment has completely dried. If you have any questions, please don’t hesitate to give us a call at 1-800-788-4142.

  64. 64

    Hi Megan,
    The bush around the mailbox could very well be an attractive hiding spot that initially attracts spiders like black widows. As you can imagine, the mailbox could have been found and they may have noticed that the mailbox is even darker and cozier than the bush – basically a free housing in housing for the black widows! You can easily treat the bush and the mail box with insecticide though. We recommend Phantom insecticide, which has black widow spiders on the label as a target pest. Please keep in mind though that Phantom is not a knockdown agent and there is a delay on the kill effect. All directions on dilution and application is on the product label and so please refer to the product label before applying the pesticide.

    I live in Glen Burnie, MD and I just went outseide to check on my motorcycle in the shed and found 2 black widows sitting in a web on my bike. I killed one but the other went back inside the bike. Guess I have to wait until it comes back out to kill that one. Does anyone know of any good outside treatment for sheds that would help with the problem?

  66. 66

    Hi Jeremy,
    We recommend Phantom. It is one of the only products we have that actually have black widows specifically labeled as a target pest. However, Phantom is not an instant knockdown kill and has a delay kill effect. If you have any questions, feel free to let us know! :)

  67. 67

    I found 30 black widow spiders with eggs today at my grandparents home neat Richmond, Virginia. They were hiding under a bag of mulch. I What is the best way to get rid of these spiders?

  68. 68

    Hi Jerry,
    Egg removal can be done by vacuuming the sacs and disposing the vacuum bag or emptying the bin in an airtight sealed bag. We recommend applying Phantom Insecticide around the entire perimeter of the home. Phantom Insecticide, however, is not an instant knockdown agent and has a delayed kill effect. However, because it is a non-repellent, it is a very effective insecticide and it is also one of the very few that we have that actually have black widows listed on the product label. If you have any questions, feel free to contact us again.

    Ooohh…I hate spiders . I do love my flowers tho.. We live in NE Oklahoma. Right in the corner and yesterday while watering my flowers I saw my first Black Widow female. While trying to spray her a male 1 came up on my brickwall !! I wasnt able to kill either one of them.. Then today out back off my porch in the loose dirt is ANOTHER female. Fat w / eggs !!!! I had a shovel in my hands this time so YES, she is dead & all her spider babies!!! This is the first time Ive seen them here

  72. 72

    Just today we found 10 black widows in a window well. I am so afraid they will come in through that window, into the basement, which is finished and we are down there all the time. Are they known to come inside or will they stay out? And what do they do when it gets cold? (I am in Colorado)

  73. 73

    Question How many are too many .I’ve been finding them for years,But this year takes the cake!!
    I can walk around my yard and find upwards to 10-12 on any given day !! I’m an organic gardener I’m down with the nature thing .But come on 4-6 egg clusters per female * 400 to 600 hatchlings per cluster. How can one organiclly controll this infestation? I use a torch but thats kinda Iffie around the 1860′s house HELP !

  74. 74

    Um, just wondering… the picture at the top of the page looks more like a brown widow. I have seen several brown and black widow here in the Baton Rouge area. The legs in that widow picture appear to show some lateral striping and the body isn’t shiny black like the black widows I’ve seen. Looks duller like maybe it’s dark brown… I’m thinking if you flip her over the hourglass is gonna be orange… Just saying…

  75. 75

    Hi Earl,
    Although black widows are more prevalent in certain areas of the country, they can most certainly be found all over the country. We recommend using Phantom Insecticide or Zenprox EC as those are the two insecticides that we carry that actually have the black widow spider on the product label as a target pest.

  76. 76

    Hi Jan,
    Black widows can come inside but are considered occasional invaders. Cold weather may force them to enter buildings. We recommend applying Phantom Insecticide around the perimeter of the home that will kill them when they come in contact with the treated area. Keep in mind though that Phantom Insecticide is not an instant knockdown insecticide and will have a delay kill effect.

  77. 77

    Hey Rich DeMarco,
    The safest way I know for removing black widow egg sacs are to remove them by vacuum and then disposing the bag or tin in a air-tight sealed bag. I hope that helped! :)

  78. 78


    Welcome. The warm winter in Virginia last year prevented the die-off of many, though the lifespan of a female is only about a year. In NOVA, you will find them everywhere.

    I’ve killed 11 at my house, and, for fun, found one at a winery on Friday to prove to a naysayer that they’re uncommon.

    Good luck!

  79. 79

    I don’t know if you still monitor this site, but it is about 9pm and I just captured a female black widow about the size of a quarter, including legs. She was crawling quickly across the floor of my carport sized screened in porch. We live in a city! In the past, i have found black widow’s under rocks and such in the country, but am shocked to find one here, especially one this large! Any advice as to why now? Why so quick and mobile? I thought they like to hide under things and not be disturbed!

    Hi Jennier,
    We check this blog daily, although it’s only during certain hours of the day. I’m sorry we weren’t available for you to ask us directly, but remember, we also have customer service phone lines at 1-800-788-4142 that are open Monday – Saturday, 9AM-7PM EST. They might always just be around on the outside, but they have been forced in because of the weather? If your location is having lots of rain or temperatures have started to drop, it may have triggered them to move inside to find shelter. Black widows are surprisingly very fast and although they will normally stay outdoors, there are instances when they will invade a home. Do not be too alarmed because they are still considered an occasional invader. We recommend using Zenprox EC or Phantom Insecticide around the window sills, door frames, and all baseboards, especially targeting corners of the rooms and under or behind furniture. If you have any questions or comments, please feel free to contact us again! :)

    Without exaggerating I have killed over 60 Black Widow spiders in two days. I am convinced it is a Spider Apocalypses! I’m in Los Angeles

  82. 82

    Hi Ian,
    Gees, I don’t know if I could handle all that in just 2 days haha but I definitely believe that something weird is going on with the bugs. Probably because of the crazy weather we’ve been having all year with the crazy ups and downs and everything in between. We’re here in Atlanta and I’m not sure what the weather is like in LA (wonderful, I bet) but the bugs (and people) have been going crazy because of the frequent weather changes. Unfortunately, it’s nothing we can control so we have to try and be as prepared as we can be. For black widows, there’s a lot of recommended concentrate sprays and a couple that actually have black widows on the label as a target pest. Those two are the Phantom Insecticide and Zenprox EC. Since they are residual insecticides, they don’t provide an instant knockdown kill and has a slight delay in kill effect, but they are still very effective. There are other insecticides that have spiders on the label like Suspend SC and Demon WP and although they don’t label the black widow specifically, I am sure that it will be very effective. If you have any further questions or concerns, feel free to contact us again.

    My home has been invaded by Black widoes and brown recluse. I have lived here (ARIZONA) for 15 years and never seen anything like it. I started spraying but getting out the shop vacuum after 10 pm works best. I have never vacuumed up that many spiders in my life, every night, my husband thinks I am nuts, but spiders come out at night. I found big female Black Widow in the windowsill with ****load of babies on her back, they went in a million different directions but I got them, was horrified. That night took shop vac with light on my head and vacuumed hundreds of spiders in one night, black widows and brown recluse. We moved to new awesome house have seen 15 to 20 Blacks already. My dog has killed at least 10 spiders she is (golden retriver) and has not got sick. She seen them coming across living room floor of brand new house. WHAT THE FU** is happening? They are all over outside of my house!!

    We are having a very bad spider problem in our house. I guess it’s my fault. I’ve always left the spiders alone because I don’t mind most spiders but now we think we have widows. They do not have the typical red hour glass but everything else is right. In fact they look a lot like the picture you have here. We keep finding very small ones and killing them as we find them, but today I found a larger one behind the oven with a bunch of egg sacks. I really have a problem with widows personally, and I have a three year old, two cats and two dogs that I worry about as well. I’m planning on calling a professional but I just don’t know what to do in the mean time since everywhere I turn, behind doors, in cupboards, behind my stove, I keep finding them. I don’t want to have to leave my house and have it fumigated but I’m about ready to use those measures.

  85. 85

    Hi Erica,
    I don’t think that fumigation is a necessary procedure to treat for spiders or even black widow spiders. You can use glue traps in the corners of homes and also treat the inside and outside of your home with a residual insecticide. We recommend Phantom Insecticide. Phantom can be applied around the entire outside perimeter of the house. Perimeter or barrier treatment usually requires you to spray about 3-4 feet up from the base of the structure and 3-4 feet out from the base of the structure. Target the door frames and window frames as well as other cracks and crevices around the perimeter that can serve as entry points for the spiders and other insects. Inside, treatment with a residual concentrate spray product is limited to crack and crevice treatment. Spray the base board area of each room, target window frames, door frames, and also treat behind and under furniture. All treated areas must be completely dry before reentry. If you have any questions or comments, please feel free to contact us again.

  86. 86

    We have a large population of black widows in our front yard. Last year we killed over forty, removed webs, cleared brush etc. I am looking for a product that I can spray that will deter them and kill on contact. The sprays I’ve used do not kill on contact, it just slows them down long enough for me to crush. I live in West Virginia and I know that it’s inevitable that I will have them but I’d like to use my yard again.

  87. 87

    I am having a furnace replaced and heating ducts repaired and reinsulated. Company did a partial repair of the ducts but tells me that the sub basement is invested with Black Widows.They wanted me to set off a bug bomb but since the basement has openings (nets over), and is connected to the furnace was afraid also of fire source. One company wants to bomb it and other said had to treat. Said the spider has an air sac and can hold it’s breath in a toxic air for up to 24 hours. true? Anyway, best way for treating under the house..

  88. 88

    Hi Frankie Eakes,
    I’m actually not sure about the air sac biology and don’t know if that is true. From experience though, bombs are generally not effective for spider control. You may need to treat manually with an insecticide that will target black widows. We do suggest a professionally done treatment since black widow spiders are potentially very dangerous. If you have any further questions or comments, please feel free to contact us again.

  89. 89

    Hello Sara,
    We do not have any products that will “deter” them and we do have contact kill insecticides. Contact kill insecticides, however, come in a variety of forms and technically, contact kill just means that the insect must come in contact with the treated area for the insecticide to have effect. Phantom is the best product that we have that will kill black widows. It is not an instant knockdown killing agent but it is one of the products we carry that actually have black widows specifically labeled as a target pest. It is a concentrate insecticide that must be diluted with water and applied with a pump sprayer. All treated areas must be avoided until that area has completely dried. If you have any further questions or comments, please feel free to contact us again.

  90. 90

    Hi, we just moved into a new older house and found 2 female and 1 male widows in our basement three days ago. We have yet to do anything to them because im afraid of forcing any we miss into other areas of the house that we actually use. So I’m going to purchase the Phantom insecticide tomorrow regardless but, when you say it’s undetectable by them does that mean it will not force them to other areas of the house? Thank you!

  91. 91

    Hello Andrea,
    Yes. However, it has a delayed kill effect. Nonetheless, it is labeled for black widow spiders and so it is the product that we recommend. If you have any further questions or comments, please feel free to contact us again.

    Hi guys,

    I have just moved to Kenya from South Africa. I have 2 massive female brown widows outside on the patio, one in the corner of the ceiling and one in the fire place which has never been used. They have both started producing egg sacks. I want to get relocate them but not kill them, I’m “nature boy”. Any suggestions on how? I have read that they are more likely to bite when protecting eggs.

  93. 93

    Hi Jonathan,
    We apologize, but we do not have the proper knowledge of relocating insects. We apologize that we are not able to better assist you.

    i have killed 3 black widows in 2 days im freaking out i hare spiders Madisonville ky im tore up worried cause where theres 3 i know theres more

  95. 95

    I live in middle Georgia (Macon) in a rural area. We have a large wooden treehouse/playhouse with attached sandbox. It has not been used much in the last few years since our kids have grown past that phase, but yesterday, in anticipating company with small kids coming over, I went out to check the area and found lots of black widow webs and egg sacs. What can I do? I tend to be organic in my gardening practices, but I realize this may call for more drastic measures. We have also found some brown recluse spiders lately. Please HELP!

  96. 96

    The past month & a half I have been busting my butt helping parents clean up property & garage & other storage buildings on southern ca property. First of all the cob webs are insane !! Then the owners of those webs biggest fattest black widows I have ever seen…..EVERYWHERE !! So I have totally cleaned out areas removed webs killed lots of them & sacs. Re packed stuff & re storted. And I swear it looks great but they r all back. Even spreading web in opened spaces along floors doorways EVERYWHERE………WHAT DO I DO?

  97. 97

    Temprid SC is a great product for spiders in general. I would recommend that you spray the Temprid on the spider webs and also come in contact with as many as you can. When you spray the spider webs and an insect lands on their web, naturally the spider will spin a web around the bug and ingest it. When they ingest their pray, the insecticide in which the insect had originally come in contact with will spread with in the spider. For Brown Recluse you will have to focus the treatment around crack and crevices.

  98. 98

    Sounds like you’re headed the right direction. You’re just missing the last piece of your puzzle. I would recommend the Temprid SC which works GREAT for spiders. Otherwise any long residual insecticide will work as well. Make sure you spray thoroughly around all crack and crevices, and spray down their webs. Spraying their webs is very important because it will help speed up the exterminating process.

    Hi ,My husband and I found a black widow in a small shed out back of our place at a campground in cape may NJ. it was scary and a big female. I am not sure if other people are seeing them I havent seen one since I left SC . Has anyone else seen them in Southern Jersey I reside in the Goucester county area .

  100. 100

    Hi Debbie,

    Black widows are usually found in the southern U.S, and not encountered so much in New Jersey. But lately, it seems as though more people are encountering them in New Jersey.

  101. 101

    Hi,we have recently been checking on a house we will soon buy and today we went to go check it out again and right where the step of the pool there was a huge black widow,my dad killed it..i was scared i knew it was a vlack widow since we went to the zoo that same day ..i really am terrified that it would bite me or my family :-/this ouse has been vacant for 5 years and there is 3 big sheds which most likely have even more spiders even snakes i just want them out!! Any tips ? please help

  102. 102

    Yikes! That doesn’t sound too welcoming. But there is a simple fix. I would recommend that you use Temprid SC and thoroughly spray around the outside perimeter of your home and indoors along the baseboard area and along all window and door frames. You should also repeat this treatment in your sheds. Once you get the insect population controlled it will naturally decrease both the spider population and snake population.

  103. 103

    Recently have found some black widows in my house. I did vacuum some egg sacs out of the vents in the floor. I was wondering if it is safe to spray the Phantom insecticide in the vents and the furnace room. I have a baby due in a few months and want something safe for him when I turn the furnace on. Thanks

  104. 104

    I would not recommend spraying inside the vents, especially with the new baby coming… Instead it would be perfectly fine to spray around the premises of the vent area.

  105. 105

    Everything I have read has stated Black Widows aren’t in Wisconsin. Well, I live in central Wisconsin and have been battling an infestation of black widows IN MY HOUSE! We live in the woods, and as a result have always had to try and get rid of wood roaches (and german roaches, yuck! And I keep a clean house!) in our basement. Last year I didn’t see a single roach in the house and thought YAY they’re finally gone! Shortly after I started finding black widows hanging around light fixtures and in the doorjams. Coincidence? Or do black widows eat roaches? Ugghh. I’m frustrated with pests! Just last night I went into the office we built in the basement, looked up, and there was a large black widow with her long legs… I killed her of course!

  106. 106

    And I should add that I’ve found them in our tractor shed, on the outside of my house, and even under my bird baths outside. But only started seeing them last year.

  107. 107

    We have a product called Zenprox EC which is labeled for black widow treatment. Its also labeled for general pest control so it will help you eliminate their food source which will also natural decrease the black widow population in the area. Good luck!!

  108. 108

    I live just north of Mexico in California and in the past few days I’ve caught 2 of what I think are male black widows. They have a black cephalothorax, a mottled brown abdomen, and banded orange-brown legs. What is odd is that the males seem larger than I would expect, closer to the size of the female, but they have pedipalps. Am I just wrongly identifying the spider? And, if they are black widows, is it likely that there are more, perhaps some hiding females? The guys that I caught were just wandering around in the middle of the day…

    It would be hard for us to tell by just the description because there are a more than a few spiders that may qualify under the description as mentioned above. However if you could send us a picture to INFO@PESTMALL.COM we could possibly take a closer look and try to identify it for you. Regardless, if you need a product for spiders including black widow spiders I would recommend Talstar Pro. Should you have any further questions, please feel free to contact us!

    I found black widow spider from my home close to the drinking water tank. Where the place found its fully roofed place and I found lots of spider nets with colorful other many types of spiders also.
    When I found it immediately informed to the Maldevian police service and they take action.
