The crickets may take care of them for you. I used to have a pet black widow that I bought crickets to feed. Eventually one cricket fought back, killed, and ate her. I named him Fredrick and had a pet cricket after that.
I'm not help at all... but WHAT IS IT WITH THE SPIDERS ALREADY?
I'm not a fan. We were sitting on the sofa watching a movie last night and I saw something scurry. That something was a HUGE and I mean HUGE (about the size of the palm of my hand) running around. SO had to catch it and put it outside... far far away.
