Fall in rural Minnesota means mice moving into the house--the same mice that have chewed up wiring in our pickup truck, chewed up upholstery in our car and, once inside, continued making messes. Just last week we spent hours tearing apart a dryer with a mouse nest. Mice are not cute and we have maintained "trap lines" with other types of mouse traps for as long as I can remember. These traps? Great! Easy to set and deadly once a mouse gets near.
