The Ultrasonic XL 200 device is an electronic pest Repeller which generates acoustic signals in ultra-high frequencies and has shown to be effective in repelling mice, rats and most of the irksome and harmful pest. Laboratory tests have shown that the ultrasound waves attack the acoustic and nervous system of the pest and thus cause them uneasiness. At a sound pressure of approx. 70 – 90 dB most of the pest give up looking for food and move along. The ultrasound waves are not harmful to the human ear. The Ultrasonic XL 200 does not interfere with any other electronic devices like television, radio, smoke and fire detectors, electronic alarm installations, cardiac pace makers or hearing devices. It is not at all harmful for plants.
