"If he needs full time employment as a mouser, (or larger vermin) send him down. In the last month, the little bastids have chewed up the brand new garage door bottom seal I just put on"

Same problem here. I solved it temporarily by leaving the door up about an inch off the floor. I'm too cheap to get 'em all a garage door opener. My Dad said clear the garage floor and hope they leave after not finding suitable quarters.
