Quick Answer
Extensive university studies and FTC investigations have repeatedly shown that ultrasonic pest repellers are highly ineffective. While they may cause temporary avoidance behavior in rodents for a few days, pests quickly habituate to the sound and resume normal activity right next to the devices.
The Science of Sound vs Pests
Sound Doesn't Penetrate Walls
Ultrasonic sound waves cannot travel through drywall or furniture, which is exactly where mice nest.
Habituation
Just like humans get used to living near train tracks, rodents quickly realize the sound poses no physical threat.

The Ankora Advantage
Nesting on the Repeller
We were called to a home in Bloomington where the homeowner had plugged in six ultrasonic repellers. When we opened the basement drop ceiling, we found a mouse nest built literally three inches away from the active plug-in device.
