Is the ultrasonic wave that drives away mice harmful to human body?

The ultrasonic wave that drives away mice has no harm to human body.

Ultrasound is a non-chemical method to drive away mice. The principle is to disturb the living environment of mice and drive them away by emitting high-frequency sound waves. The frequency of the ultrasonic mousetrap is between 20kHz and 100kHz, which is beyond human hearing range. Ultrasonic mousetraps have no auditory or physiological effects on human body.
