Guns were discussed, but that fucker is just so quick. I had a long pole with a sharp end, and I positioned it at the very edge of his hole, and I waited patiently, quietly. Sure enough he popped his head up and I shoved the stick as fast as possible. It was just a centimeter from his face and he still managed to dodge it. I ended up with a cut on my hand from the end of the pole. A shotgun probably wouldn't be a great idea in my back yard, no doubt someone would call the cops.
