Abstract: The present disclosure provides a pest repellant system that includes pulse generator circuitry to generate pulses from a power source. The frequency and amplitude of the pulses are selected based on a selected pest species. One or more emitters are coupled to the pulse generator to generate pulsed fields to interfere with navigational/landing/nesting abilities of the selected pest species. The pulse generator circuitry includes filter circuitry to remove/attenuate unwanted frequency components of the pulses, in accordance with regulatory and/or government requirements. The pulse generator circuitry is encased in a housing structure to provide moisture and tamper resistance in accordance with regulatory and/or government requirements.
