I had a mole move into my lawn, and was starting to act like the Bill Murray character in Caddyshack - I tried everything and could not get rid of it. I swear I heard it laughing at me. My yard looked like a war zone: hills and craters everywhere.
You would not think one little creature could do so much damage, but it did, and the Mole Patrol came quickly, set some traps, and that was the last I heard of the mole.
And I lived happily ever after.
