Here are questions related to Getting Rid of Black Widow Spiders.
I am looking for an organic way to get rid of black widow spiders.
I put fresh spearmint in my closets and under furniture to make sure I do not have spiders. I do not know if it will help with black widows but nothing lost if it does not.
I had an outdoor storage unit that was full of spider webs and spiders and when I put the spearmint in the unit was clean I also do not have anymore spiders in the house. No more spiders for me.
Is it dangerous to smash a female black widow spider in your home?

Black widows live in clusters because they just do not travel far. So if you see one you can be sure there are more around. You need professional help. Not just some person who comes to spray your home but a real professional company that knows how to get rid of them,

Last summer, I had black widows all over my yard. Most of them were female, and they built there little web underneath the ring all over my easy set up pool. Just a few days ago, my kids were playing in the sandbox and one was crawling beside my son. I thought they would be hiding since it's January and colder. I have a 2 year old and a 5 year old and will have a baby by next spring, so I am terrified of what they can do to my kids. Does anybody know what to do to get rid of them? I was hoping to find a way without chemicals, since I'm afraid it wouldn't be good for my family. Thanks for anyone's suggestions! Candy
I believe black widows are similar to the Redback spiders we have in Australia. They are everywhere and you just have to teach your kids to recognize and avoid them. Collect a good big adult in a clear jar and show it to your children, explaining the have a very sore bite, they mustn't touch them and to tell Mummy if they see one.
When you see the nests/egg sacs in the garden just spray them with insect surface spray - they nest in nooks and crannies, not somewhere your children are likely to be crawling so the spray would be healthier than a painful bite. There is an antidote so the bites are not fatal, just painful.
Most of the bites in Australia happen when people put on clothes with the spiders inside so it may be helpful to add turning clothes inside out and shaking them when you are teaching your children to dress and not to leave their clothes lying around outside the house. (01/12/2005)
Definitely contact pest control. Whether eco-friendly or otherwise, this is a serious issue. You probably already know that black widows only bite when protecting themselves or webs/eggs, but you and your children will find it difficult to be on the lookout constantly. Spider bites are scary as, often, they don't hurt until hours later when the neurotoxin has started to break down the area where it has been injected. The sprawl of urbania grows ever onward into many animals' domains, and these types of situations are found often. Where I live, people find rattle snake nests alot. YIKES!
Anyway, pest control will, even if they can't guarantee direct control of the spiders, control the bugs in your yard which lure the spiders over. Closing the buffet will keep the customers to a minimum.
Scientifically, black widows make people (even the little ones) more sick than mortally wounded. Cats, however, apparently find it their duty to battle with these tiny creatures and lose 90% of the time. I wish you strength and health with your tiny adversary! (01/16/2005)
I also have problems with Black Widow spiders I live in Idaho and they are a constant problem here. Something I do that seems to keep them under control is bug bombing the house every 6 months or so. You can buy the bug bomb sprays at Wal-mart and some of them are enviromentally safe
After the spray I just wash down all surfaces that weren't covered and vacuum thoroughly. You can even place blankets or sheets on your couch and then just throw them in the wash, so no chemical residue is left on furniture. I also spray the outside of my house with a pressure washer to try and knock down any spiders there. (10/06/2005)
First of all, if you have them inside your house, you have a real problem - especially if you see an egg sac. First thing, go through your house and garage and look in every corner for any web. You can always identify the black widow's web if you look closely. It's a cobweb with no rhyme or reason, but the strands appear very sticky. Once you see one, you will be able to identify them. Anyway, if you see this web, the spider is nearby, carefully sift through it until you see the evil black SOB, then squash it. Wear gloves, wear socks, keep your distance, and make sure you take out the egg as well.
Everyone who asks about getting rid of them outside: just focus on the areas they live or areas you've seen them in (woodpiles, rock piles, water meters, etc). Smash (don't spray) the spider and be absolutely sure to destroy the egg as well. If you don't take out the egg, they will keep coming back. After one summer of carefully searching and killing them and their eggs, you will notice a drastic dropoff in the frequency of sightings. (08/21/2007)

Widow Spider Control Methods: Non-chemical (Prevention)
Chemical Widow spiders are typically not affected by general pesticide applications (baseboard sprays) because they avoid the treated areas. Individual widow spiders can be killed by direct application (to the spider itself) with a labeled pesticide but they may not die immediately and you risk an intoxicated spider running around loose in the house. By far, the non-chemical methods of prevention and removal are your best bet. If necessary, silica dusts or microencapsulated pesticide formulations may be used in attics and crawlspaces and on window frames to prevent spider re-infestation. In rare situations where widow spiders are numerous indoors, you should seek the services of a professional pest control company.

Remove any and all spider webs from your yard etc. with a long stick while wearing boots, (smoosh). Spray any spiders with spider insecticide if you're too frightened to smoosh them.
Spray any areas where black widows have been known to be with Lemon Pledge. Spiders taste with their legs and hate the strong oily citrus residue. They should not return to those areas if you keep them sprayed with Lemon Pledge on a regular basis. (07/11/2008)
I live in KY, and I have black widows all over the yard. The only solution that I have found to get rid of Widows is to get rid of my beautiful landscaping. Rocks, such as rock walls around ponds, landscaping rocks, and even sand in which the pool sets on, is the perfect haven for these little, but big scary creatures.
After losing my landscape, I hardly see Widows anymore. I have left a few rocks for some landscaping in which I still can pick up and find that glossy black red hour glass running for cover, and that's when the hillybilly dance begins. I have tried everything possible and unless I spray the suckers directly it doesn't seem like anything keeps them away for good. Hope this brings you some hope, although you may loose your beautiful landscape. (08/05/2008)
Widows are primarily nocturnal, preferring the cool and darkness to daylight. That's probably why they like dark places like the corner of your garage or wood piles. In outdoors situations, they'll hide in cracks and holes during the day, coming out at night to hang in their webs and feed. My wife and I are typically indoors at night, but recently we returned home late one evening and found the place besieged by Widows. I killed two in the front of the house, and at least three (some of the smaller ones were hard to tell, though they were likely babies undergoing color change) in the backyard, mostly around our spa that we like to use most nights! I suffer from a peculiar form of arachnophobia: fuzzy spiders like the jumpers or even a tarantula seem kind of cute to me (not saying I'd adopt one as a pet), but the slick, shiny spiders with big abdomens and pointed legs absolutely freak me out! Needless to say I was pretty upset after this nighttime discovery.
The next day, I took a broom and cleared out as much cobweb and junk as I could all around the house, then soaked the perimeter with an indoor/outdoor pest control spray. I used the kind commonly available at hardware and home supply stores, comes in a big jug with a detachable sprayer. I paid particular attention to the cracks and crevices in brickwork and siding where I figure the little buggers hide. This morning I found a couple of dying Widows who apparently had emerged during the night and succumbed to the spray (which is designed to stick to surfaces and keep working after the carrier fluid has dried). I'd like to think that there are several more unseen ones that I killed as well. Looks like this will have to be a regular task around our place.
I absolutely hate Black Widows, just hate them. I, like most of you, have a one year old daughter and worry to death about her getting bit. I have an abnormally large amount of these critters. I live in Northern California and seem to have found a solid solution to get rid of them. I usually just go out once a week at night with a flashlight and find them then kill them. I can count in a given night at least 10-20 Black Widows all over my yard, against my house, that is where I find most of them, they are just everywhere.
I have tried just finding them at night and spraying them with Raid Ant and Spider killer and it does kill them them, but very slowly. I recently, just today, bought a product (at Walmart) called Spectracide Triazicide in an attach to your hose model. This Triazicide is serious stuff. I sprayed my entire outside, yard, fence, house, all the perimeter of the house and where I know I always find them. As many of you know, insecticides just don't kill Black Widows, just kinda makes them slow. This stuff worked. As proof, I have attached pictures of the captured ones I found dead. I also attached a picture of the product I referred to earlier. I know I will have to repeat this process about 2-3 months, but it worked. It also killed all the other critters, like all the dang ants and other spiders. Give this a try, it worked for me. One thing to say, Black Widows do take a while to die (like an hour), but they stay in their webs so they are easy to spot. Hope this helps. Oops, just found out I can only upload one photo, so I chose the buggers. Just look for the product mentioned above that attaches to your garden hose and just start spraying. (09/04/2008)
I can help some people sleep a lot better at night. First, I have read all the posts and I hope someone finds their way down here to read this. There were 2,500 bites from black widows reports in 2006 (this is 2008 now when I'm writing this), but a lot go unreported to C.D.C because not everyone goes to the hospital (most do because of the pain).
Nobody died that year from black widow bites but four did die from other spider bites. Spraying your yard with bug killer by the hose works to keep down population because it kills what they eat but this job must be on going. Now for the best part; in every corner inside place a sticky fly paper trap (this will catch them 100%).
Also clean your house often and pick up trash, boxes and vacuum often. Now for the best part make sure your bed is not on the floor, around your bed post at the bottom place sticky fly paper traps (sticky side facing out and overlapping, and around the bed post, on the bed post) make sure blankets or anything on your bed is not touching the floor! Now you can sleep in Peace.
