There is a gopher or chipmunk that is living under my cement front porch. He is making a mess of the yard with his holes. I have tried filling in the holes with a lot of water and then mud, but he just digs another hole nearby. I have tried putting mothballs down there first just to make it smell nasty, but it doesn't seem to bother him.
I'm ready to become Caddyshack's Carl Spackler and blow up the whole yard.
How can I get rid of this thing? Any and all advice will be appreciated.
