1, useful: because mice are sensitive to high-frequency sound waves, the ultrasonic mouse repeller interferes with the living environment of mice by emitting high-frequency sound waves, thus achieving the purpose of repelling mice.
2. Not very useful: Different kinds of mice have different sensitivities to ultrasound, and some mice may have immunity or adaptability to ultrasound, so they are not affected by it.
3. The effect is limited: the ultrasonic wave will be blocked and reflected by obstacles in the propagation process, which will lead to the attenuation of sound wave energy, and then affect the rat repellent effect. The effect of ultrasonic mousetrap is also affected by environmental conditions and usage methods, such as sound wave frequency, sound wave intensity, equipment location and other factors may have an impact on the effect.
