Multi-functional Ultrasonic Pest Repeller (For small spaces)

HP-307 Multi-functional Ultrasonic Pest Repeller is designed with “Multiplex Modulated Sweeping Ultrasonic Sounds”. It combines 2 unique technologies, “Automatic Frequency Change” and “Adjustable Sweeping Speed” which can prevent rodents from getting used to a single-frequency sound by changing frequency and speed all the time. Automatically change frequencies and alter their sweeping speeds 1-60 times a second.

These intense ultrasonic waves (20~65 kHz is out of the hearing range of humans) directly attack rodents’ auditory and central nerve systems to drive away these unwanted animals from your place without using toxic chemicals or killing them. Ultrasonic frequencies between 20~65 kHz is inaudible and harmless to human beings and most of household pets; sonic frequencies under 20kHz can be used outdoors to repel birds and wild animals.
