Do Ultrasonic Pest Repellers Work?

"Do Those Plug-in Ultrasonic Pest Repellers Actually Work?"

No.

Or rather, not in any way that matters. They operate at a different frequency, sending out sound waves above the range of human hearing, and manufacturers claim the noise makes life unbearable for mice and rats. In controlled lab settings, some rodents do show brief avoidance behavior—brief being the key word. Within days, they get used to the sound and carry on as if someone on the subway was scrolling through reels on their phone.

The Federal Trade Commission has warned consumers repeatedly that manufacturers haven't provided scientific evidence to back up their claims. Independent studies from multiple universities confirm the same conclusion: ultrasonic repellers don't reduce rodent populations in real-world conditions. Walls, furniture, and equipment block the sound waves entirely, creating comfortable dead zones where pests can nest undisturbed.

In a commercial building with drop ceilings, wall cavities, and miles of pipe runs, a plug-in gadget is about as useful as that small plastic box we started with. Effective rodent control in restaurants, hotels, and office buildings requires sealing entry points, eliminating food sources, and ongoing professional monitoring. In other words, there's no shortcut you can buy for $29.99 at the hardware store.
