Used to live in a tornado magnet, I mean mobile home, in Iowa and they lived under it but the herd. I had to crawl under there to fix the telephone line once and swore I would never do it again. THey look much much different when you are nose to nose with them. I don't care if they are non-poisonous, dead from a heart attack is the same dead as venomous causes!!! Had one that lived in the down spout of the rain gutters and would come out when you hit the spout. He was big and nasty. I think you can get an infection from them if they bite you.
