An electronic based pest repellent is presented as an alternative to pesticides commonly in used in farmlands and homes. It is made up of power supply unit (PSU), Peripheral Interface Controller (PIC), switches for mode selection, LCD display, power amplifier and speaker.The system was designed at the Computer Engineering Laboratory of the Abubakar Tafawa Balewa University. The device generates repelling signals in the range of 30 and 50 kHz within the ultrasonic frequency. A digital oscilloscope was used to test the ultrasonic signals within the above range for ten experimental trials for different type of pests. The results of the trial showed that the pest repelling ranges were highly precise to designed specification. The outcomes of this study are comparable to those obtained from the commercial ultrasound. It has also established that the simulation and experimental results were consistent within a measuring uncertainty of ±5% at an affordable cost of one-fifth rate lower than the propoxur insecticide.
