I’ve seen parvovirus decimate them on a place years ago.

I’d trap them but I’d never poison them. Too much risk for other, non target animals. Outside of rats and insects around the house, I hate even the thought of putting toxins of any kind, out into the woods. I’ll hunt the heck out of them, trap them, or ven pay for trapping if I could afford it….but there’s a ton of folks around that’ll shoot or trap them for you, just for the asking. You don’t need to kill all of them. They know when some are becomes dangerous, and many will move out.
