Construction of an Ultrasonic Pest Repeller
Abstract
An ultrasonic pest repeller (UPR) was constructed to repel pest like rodent from home in order to prevent damage and possible infections or diseases caused by rodents. Rodents can perceive ultrasonic sound of frequencies within the range of 20 to 65 kHz. Our UPR when tested emit varying ultrasonic frequencies approximately within the range of 20 to 50 kHz. We found that these varying frequencies are like sound produced by Jackhammer and causes auditory stress to rodents and discourages them from habituating within the environment where this sound is effective. Ultrasonic frequencies are frequencies above 20 kHz. This work was simulated with electronics simulator software called PROTEUS to study and ensure its operating characteristics before construction. This device is more humane and sanitary to use in home as they do not involve traps and poisons which are harmful to man. Also, the varying ultrasonic frequencies emitted are inaudible to man.
