Ultrasonic pest repellent claims to repel pests (e.g., rodents and insects) can cause disturbance to the theses pests by emitting vibrations and ultrasound waves that penetrate behind walls. The bugs and rodents cannot tolerate the ultrasonic sound and vibrations; thus, the pests need to stay away.

Upon our research, studies, and according to some consumer reviews, it even claims that electronic pest repeller devices really live up to their product and manufacturers promise. Remember that the whole pest control process could take time. It works silently (literally because you can’t hear the sound), and the goal is not achieved overnight.
