Maybe a crossbow. You can get pretty close to the suckers. Pellet gun will scare them off but they'll come back. Probably doesn't make it through thick fur but barer skin might absorb a pellet under it.

I knew a guy in a rural setting with a large humane trap. He would drown them in a 50 gallon barrel. Watched him do it once. Kinda harsh - the little guy shook that cage pretty hard trying to get out. You could hear it knocking the barrel and see water sloshing out. The water needed to be almost full to cover the highest point.

Not sure if the others learn to avoid the trap. Probably good to hide it right away so the others don't see though they often go out together socially.
