No matter where you live, rodents can become a huge problem. Once the little buggers manage to get inside, they get everywhere and into everything. They are houseguests you don’t want. If you can’t get a cat and don’t want to deal with the issues traps and poisons leave behind, the Ultrasonic Pest Repeller may be the solution to your problem.

This device is made to push out rats and mice but it claims to also discourage insects from taking up residence as well. All you need to do is plug it in and it emits a high frequency electromagnetic wave that rodents can’t stand. If they’re not already in your house, it will keep them from coming in. If they are inside, it will make them want to leave.

The device has a low blue LED light to let you know that it is on and working. An exterminator is probably your best choice but if you can’t afford one or you’re looking for a more humane way to settle things with pests, the Ultrasonic Pest Repeller is $29.95.
