How can I get rid of Black Widow spiders?

Question

Are there any insects I can get that eat them? Or any trick to deter them? Or good pesticide?

Answer 1

According to Wikipedia:

"...There are various parasites and predators of widow spiders in North America, though apparently none of these have ever been evaluated in terms of augmentation programs for improved biocontrol. Parasites of the egg sacs include the flightless scelionid wasp Baeus latrodecti, and members of the chloropid fly genus Pseudogaurax. Predators of the adult spiders include a few wasps, most notably the blue mud dauber, Chalybion californicum, and the spider wasp Tastiotenia festiva. Other species will occasionally and opportunistically take widows as prey, but the preceding all exhibit some significant specific preference for Latrodectus...."

Answer 2

There are spray sold at outdoor supply store that kill spiders. The spray shoots out a long distance so you don't have to get to close to the spiders. I am highly allergic to spider bites so use that stuff like crazy when I see spider! I bought mine at Tractor Supply. I think Wal-Mart sells good pesticides that can kill them to. Good luck killing those nasty things!
