Pest Control, using pest repellers, both electro-magnetic and ultrasonic, is fast becoming an accepted environmentally friendly method of pest control. Electronic Pest Repellers are mostly used against infestations of mice and rats and found to be very effective against rodents. Some good results have also been achieved against insects such as cockroaches, earwigs and ants but successful control of these insect pests is patchy. Pest Control Direct has been selling electronic pest control products for over 8 years and have found them to be effective in controlling many pest problems. You will also find Pest Stop Rat Zappers ( electronic rat killers ) and Mouse Zappers ( electronic mouse killers ) and Dust Mite controllers.
