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.
