      Oh hell no to living where number 8 resides! :eek: Spiders 1, 2, 7 & 10 live on my property. I shudder at the sight of them. As someone who was raised in the country and was never taught to look for and avoid these things, I got bit by a black widow when I was younger. Talk about painful. I teach my kids to look before grabbing, move things with your shoes first and try to roll them over, do not leave your shoes outside, and if you see one let me know and I will kill it. Good article for people to put a visual on these pains in the….skin.

      I have been bitten by a recluse and black widow. The black widow wasn’t much of a problem but the recluse was a bitch. :cool:
