Terry - Interesting that you mentioned scorpions. We used to have them here when we first moved into our home after it was built. But I have not seen a scorpion in years! I forgot all about those little bugs. I see brown widow spiders here, but haven't seen any black widow spiders. The worst is the brown recluse spider. Those can do some nasty damage to flesh.
If there is any poison ivy around, I've not seen it. And I haven't had any skin rashes, so I guess I am safe for now. I get other annoying vines and trees, but not PI.
