With so many amazing things going on in the world of science and technology, we still don't have an effective solution to ward off pests electronically. Pesticides, insecticides and other repellents are toxic and dangerous to human health. Electronic Pest Repellent (EPR) is a new technology that is cheap, environmentally friendly, effective and poses no risk to humans. Electronic pest repellents are electronic devices that are capable of producing sounds in the ultrasonic frequency range that are inaudible to the human ear but are audible to pests such as rodents, birds and insects. Sounds of this frequency (10-100 kHz) are annoying to pests and leave the place due to severe hearing impairment. The device can be used by the general public to repel mosquitoes, insects, cockroaches and by farmers to repel rodents, insects and other pests.
