The "Have a Heart" traps are really easy to set up and use. The Lethal traps that we have tried in the past never caught a thing. But the live traps have worked most of the time. Whats a pain in the butt is finding a place to turn them loose! The fairgrounds, near some assholes house, and the realization that for every mouse I trap, there's ten that learn not to go into the traps! Mice ain't dumb! Irritating, but, not dumb!
