We offer a range of ultrasonic pest repellers to rid your home and garden of Cats, Dogs, Foxes, Birds, Pidgeon & Squirrels - to name but a few. The ultrasonic Cat repeller is the most popular, closely followed by plugin repellers for mice and Rats. But whatever the nuisance pest, the ultrasonic units all work on the same principal by producing an ultrasonic noise that a Mouse, Rat, Fox, Cat, Squirrel etc, simply wants to get away from. It's not always an instant cure, but in most cases results can by seen after only a few days.
Mammals have different hearing ranges. These different ranges (frequencies) are measured in Hertz (Hz). Sounds are classified as infra sounds (below the human hearing), sonic range (within the range of human hearing of 64Hz - 23,000Hz) and ultrasonic (above the range of human hearing). Most pests respond to ultrasonic sound that we humans, cannot hear. Mice respond to higher frequencies, whereas Badgers and larger dogs can hear lower ranges. Some of our ultrasonic repellers will even get rid of insects such as Spiders!
