Yes a live trap works really well. I had a problem with them, and used a live trap and relocated them. Just make sure if you are using a live trap it is strong enough to hold them. I had a couple tear the hell out of that trap, and now it isn't worth using for coons anymore. Also a bigger dog does seem to help? And a .22 with hollow points work really well if you want to dispatch them also. Good luck I hate coons!
