It works by sending a electromagnetic signal through the wiring of your house. The frequency is such that it will disturb the little rodents’ nervous system which will make them so uncomfortable that they will find quieter quarters to live.

The Pest Offense cycles itself in 3 minute intervals which prevents the mice from getting used to it. The minute they think it’s gone, it comes back to torture them.

Because it works via the wiring inside your house, it prevents them from making nests inside your walls.

This is much more humane than using poisons and much safer for you, your kids, and your pets as well. It is a much more cost effective solution. It will keep protecting your home for as long as you have it plugged and working.

It also states that it works against roaches and other insects.
