Electronic Pest Repeller

Description

The ultrasonic devices are plugged into a home’s electrical receptacle outlets which then purportedly emit high-frequency sounds that are disruptive to pests. The sound supposedly causes a physiological response known as audiogenic seizure response, which is characterized by non-directional running, convulsions, and possibly death from cerebral hemorrhage. The theory behind the devices is that confused rodents eventually flee when the disruption prevents them from gathering food, breeding, building nests or communicating. Ultrasonic devices are popular and appealing to consumers because of their ease of use and the fact that they are silent to human ears and allegedly eliminate the need for traps and poison, which are thought by some to be inhumane forms of pest control.
