Ultrasonic pest repellers use high-frequency sound to deter mice, rats and other pests without traps or bait. This collection brings together plug-in, battery-powered and nightlight models from Weitech and The Big Cheese, plus the COMPO Barrière Radikal Ultrasonic 2 in 1. There are also dedicated devices to deter birds and mosquitoes, and the Weitech Garden Protector 4 for outdoor areas up to 200 m².
Buying tip: choose a repeller by the area it covers, from 45 m² to 280 m², and check whether it is made for indoor use or, like the waterproof Weitech rats and mice repeller, for indoor and outdoor use. Prices range from €17.50 to €166.30.
