The Pestclear Slimline 2500 uses electrical cables in the home to transmit a very low-frequency sound, called infrasound, which is undetectable to humans, cats, dogs, fish, reptiles, and birds, but is very disruptive to rodents such as mice and rats, and some crawling insects. It allows you to target specific pests with very specific frequencies and features a unique 'Pet-Safe' setting, making it suitable for use near rodent pets like hamsters, gerbils, and rabbits. The device also has two separate programs for the electromagnetic signal.
