Abstract: This application discloses an apparatus and method for generating and radiating energy at specific radio frequency wavelengths known to adversely affect the nervous systems of small insects such as flies, gnats, cockroaches, termites and the like wherein each is affected by a different frequency or range of frequencies; the apparatus containing a power supply, a voltage selector circuit for generating sequences of specific voltages, a modulator circuit to amplitude modulate each specific voltage about its center level, a multiple frequency generator to convert each modulated voltage into a modulated frequency of both fundamental and harmonic content, a radio frequency transmitter circuit, and a random interval timer circuit to energize and de-energize the radio frequency transmitter circuit in such a manner as to prevent the pest from acquiring an immunity to the radiated energy.
