My vote is no. I love it when I see snakes come into my yard since I don't get to see them often. I live just feet from a wildlife reserve, I usually just catch and release them, or just watch them slither on by.
I live in NW Fl. and I have seen my fair share of vemonous snakes too. I don't kill them either, I usually just call my neighbor (vemonous snake wrangler expert) and we catch them and place them back deep in the reserve. A majority of the vemonous snakes we get are diamond backs, the biggest one I have seen in my neck of the woods was a 6 footer, and by the looks of it, it was an old one.
Now if say I saw a "pet" snake such as a ball python, burmese, boa, etc. I would take it in, quarantine it (of course), take it to the vet, get it back to health if its sick, and when it passes quarantine and is healthy and eating, put it up for adoption. Fortunately I have never had to do this since I have never seen any pet snakes roaming around my area.
