Ultrasonic pest alarm 90m2 Weitech

Weitech pet alarms generate and emit complex sound at very high sound frequencies (ultrasound) and high intensities. This ultrasound is inaudible to the human ear, but rodents and most bugs can hear and sense this high frequency sound in some way.
The continuous and alternating intensity and frequency of the ultrasound disrupts the nervous system of the animals, disrupts their communication and habits and breaks their food chain, causing them to lose their prey and leave the area protected by the devices.
Ultrasound behaves in the same way as audible sound: it bounces off hard surfaces and is absorbed by soft surfaces. It does not penetrate walls and is most effective indoors.
Installation and use with electrical appliances:
Simply insert the appliance into any electrical outlet. Simply plug the appliance into any electrical outlet. The device requires no maintenance or recharging. Operate the appliance continuously, occasionally moving it to another outlet if necessary. For best results, place separate units in adjacent rooms and on different floors. Expect results after two weeks! Continued use will prevent pests from re-infesting.
