The best way to deal with pests is to keep them from coming to you in the first place. This nifty Transonic Pro Electronic Repeller device drives pests away with sounds they can’t stand – in an area up to 3500 square feet! Repel rodents, insects, bats, spiders, even skunks and raccoons with psychoacoustic jamming, which is not a heavy metal concert gone horribly wrong, but rather intense, variable pitch ultrasonic and sonic sound waves that create a noisy, hostile dynamic sound environment. The noise is intolerable to pests yet friendly to pets and humans. Safe for use indoors and out, and at food establishments, farms, warehouses, homes, and more. Weather-resistant metal housing.
