The mouse repeller is a kind of device that can generate 20kHz-55kHz ultrasonic wave to effectively stimulate and cause Rats feel threatened and disturbed regarding as 200Hz-90000Hz mouse auditory system which is using professional electronic technology throughout years of scientific research on rod......

Since the physical rat repellent method is adopted, the purpose of using ultrasonic waves is to effectively drive rats away from the working and living environment of home, office etc, so just adopt humane way to repel them instead of killing.

Ultrasonic waves have the characteristics of not penetrating obstacles, strong directionality, and fast attenuation, this is the disadvantage of ultrasonic waves and also its advantages. Using a higher power mouse repellent. A better removal effect will be achieved.

The human auditory system cannot respond to the frequency above 20000Hz, so our ears cannot hear it at all, and the power of the ultrasonic mouse repellent has not reached the ability to penetrate the human body, so it has no effect on the humans.
