Question 1

How does ultrasonic pest repellent work?

Accepted Answer

Ultrasonic pest repellents generate high-frequency sound waves (10-100 kHz) that create auditory stress for pests. These frequencies are unpleasant for insects and rodents, causing them to move away from the sound source.

Question 2

Can humans hear ultrasonic frequencies?

Accepted Answer

No. The human hearing range is typically 20 Hz to 20,000 Hz (20 kHz). Ultrasonic frequencies above 20,000 Hz are inaudible to humans, which is why you may not hear anything while the app is running.

Question 3

What frequency repels mosquitoes?

Accepted Answer

Mosquitoes are typically repelled by frequencies in the range of 18,000 to 22,000 Hz (18-22 kHz). PestAway includes a dedicated mosquito preset at 20,000 Hz.

Question 4

Does PestAway work on all devices?

Accepted Answer

PestAway works on any device with a speaker and Web Audio API support, including desktop browsers, tablets, and smartphones. However, most mobile device speakers can only produce frequencies up to around 20,000 Hz. For best results, use a computer with quality speakers.
