The concept behind utilizing noises to ward off bugs was first embraced by the Chinese thousands of years ago. They used devices that were run manually and emitted sounds to expel bugs and pests from their crops.
Ultrasonic pest repellers as the name implies, use ultrasound which essentially means noise of more than 20,000 Hz. This frequency of sound is practically undetectable by the human ear. Ultrasonic sound is thought to trigger particular signs in bugs such as confusion, convulsions, and even death which is called an audiogenic seizure action. Insects are then expected to leave the area that causes this kind of distress for a friendlier environment.
