It sucks for sure but hey, there's nothing anyone can do really. Just kill em when we see them. But beyond that there's no real way to get rid of them. I've heard and seen some less than legal ways to kill them. One day I walked up to a piece of piano wire and a piece of meat hanging from a tree about 4 ft off the ground. Had a heavy heavy gague treble hook attached to it.... I'm sure you can figure out how that works...
