Yep, if you can't outsmart it, you gotta kill it!

Living in the woods as I do. Over the years I have had the same problem with a variety of trouble animals, including a recent run in with a groundhog. The simple solution is a quick trip to the local Wal-Mart and buy yourself a $29.95 scope equipped pump-up BB-gun, but give it only 2 pumps. Not enough to kill the critter, but just enough to encourage him to stay on your neighbor's property. It works every time. There's no body to get rid of and there is some sport to enjoy. This technique has worked for me on everything from a ground squirrel to a black bear. Although as I recall the bear did take 3 pumps and a secure hiding place from which to shoot. Just aim at his tail. Hell you might even learn to use a gun proper like.

PS. With no calories to burn, from eating vermin, your belly may even stay in check. Now there's a Win win
