it might be dangerous if it is a black widow, but it might not be. just squish it to get rid of it.
it gets rid of pests and its "husband"
The first thing you need to determine is why you want to get rid of the spiders. The ones in the U.S. that can kill people are the black widows and the brown recluse spiders. Black widow bites can only kill children and infirm adults. Since antivenoms have been available, nobody has died from their bites. The brown recluse spiders can produce necrotic bites, and sometimes more serious symptoms, symptoms that can produce death, can result. Black widow spiders do not like to live in human habitations, so if you spot one the easiest solution would be to let it drop into a bottle, cap the bottle, take it outside, and release it at some distance from human habitation. If you kill all spiders in your house, then there is a chance that many brown recluses spiders would get in, and there would be no other spiders around to catch and eat them. If you are intent on killing, then the next problem would be what to use to kill them. A flyswatter would do for individual black widow or brown recluse spiders. If you don't like that solution you could try diatomaceous earth. That is not a drug like DDT. It is made up of large numbers of diatoms, or at least the shells of dead diatoms. Contact with them can pierce the bodies of insects and spiders.
This is a tough question and the answer is probably not what you are seeking. Black Widows are very private creatures and prefer woodpiles, rock piles, dark and damp environments and do not generally come out to bother people unless provoked and even then, a bite is rare. The chemicals used to kill Black Widow spiders is unknown in consumer world with exception of one product that I have been able to locate: BAYER Total Home Defense. This product contains B-Cyfluthrin, which is said to be able to kill or rid your home of the Widow and Recluse species of spiders. Althought this had not been proven, a quick phone call to several pest control facilites in the area and I've found that B-Cyfluthrin is chemically compounded in several of the pest control mixtures that I've been told work. It is known commercially as several different chemical names, but nonetheless, is still the same. Products such as Ortho MAX and SEVIN insect control, specificly exclude the Widow, Recluse and Scorpions as pests that their product will kill. So, if you want them gone, keep brooming away their nests, smash the adults that you can find and keep debris piles to a minimum if not completely void on your premesis. This will discourage them from continuing to form webs and hideouts on your property in the future. The truth is - they are very hard to get rid of, once they are present in your home, shop or garden.
