Bird-X Transonic Pro is perfect for repelling pesky critters
A 5/5 star product review
This device is excellent to ward off raccoons, squirrels, chipmunks, mice etc. It is a humane way of getting rid of unwanted pests and proved to be very effective. I have a whole string of the units spread out in my attic and operate them for periods of two or three days and then turn them off for a week or so. The result is no pests.
