Electronic ultrasonic pest repeller

Devices like these claim to emit high-frequency sound waves that irritate common household pests, causing them to leave the area.

Effectiveness and Science

Scientific Consensus: Independent studies and pest control experts generally conclude that these plug-in ultrasonic devices are ineffective.

Limitations: Ultrasonic sound waves cannot pass through solid walls, furniture, or heavy curtains. This severely limits their coverage to a single, open line-of-sight space.

Habituation: Even when pests initially react to the sound, they typically adapt and get used to the noise over time.
