It might interest you to know that as a special education teacher, I kept as a pet a black widow on my desk for years. We fed it flies and crickets. It’s important to know what is and what isn’t a real threat. Black widow bites ARE serious but they seldom bite unless threatened by being touched and they often bite “blanks”. No venom, like a warning shot. They don’t live in my house but I’m not inclined to kill them if I happen to see them outside. I’m a lot less forgiving of brown recluse who happily burrow into my bed and bite because as far as they are concerned, it’s their bed now and I can just jolly well move over.
