I have these rodent devices in the house and garage. Originally got them for the house on Cape Cod which had only one sensor (still have them). Also have the new ones. Not for mice but for bugs and spiders. The garage is free of insects and spiders. Occasionally I see a spider on the wall in the garage which is behind the Repeller.
