How to Get Rid of Black Widow Spiders
HOW to GET RID of BLACK WIDOW SPIDER – POISONOUS SPIDER
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.
INSPECTION
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.
SAFETY EMERGENCY PROCEDURE
A person might not always feel the black widow spider bite until later.
- 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.
- Common reactions are said when a black widow spider bites is an entire body ache especially in the legs.
- Other symptoms: alternating salivation, dry-mouth, and paralysis of the diaphragm, excess sweating can occur.
- 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.
- A person bitten should seek immediate medical help and get treated.
- Clean the bite well with soap and water
- Apply a cool cloth over the bite and raise the affected limb about heart level.
- Take aspirin to help relieve the pain.
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.
CONTROL METHODS
Prevention:
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% CS, FenvaStar 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% CS, FenvaStar 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% CS, FenvaStar 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% CS, FenvaStar 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?
Friday, 15. October 2010 17:59
Hello,
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!
Wednesday, 6. April 2011 11:14
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!!
Saturday, 16. April 2011 11:42
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!!!!!!
Friday, 22. April 2011 12:47
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!!!!
Saturday, 30. April 2011 14:51
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?
Sunday, 26. June 2011 19:08
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?
Monday, 27. June 2011 8:55
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.
Monday, 27. June 2011 9:02
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.

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?
Tuesday, 5. July 2011 22:12
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?
Wednesday, 6. July 2011 16:28
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!
Wednesday, 6. July 2011 17:17
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!

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.
Friday, 8. July 2011 17:03
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?
Friday, 5. August 2011 16:09
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.
Wednesday, 17. August 2011 9:18
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!!!
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.
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…
Thursday, 18. August 2011 14:51
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!

Hi,
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.
Thursday, 8. September 2011 11:02
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.
Thursday, 6. October 2011 22:42
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
Tuesday, 18. October 2011 16:39
Hello,
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!

We set up and decorated our Christmas tree yesterday. This morning, I found a black widow on it. Any thoughts on what to do?
Tuesday, 6. December 2011 10:01
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.
Tuesday, 17. January 2012 2:03
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.
Monday, 23. January 2012 10:58
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!

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?
Monday, 12. March 2012 10:12
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 info@pestmall.com

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
Friday, 18. May 2012 13:11
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.
Friday, 18. May 2012 17:44
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.
