Abstract: An apparatus for repelling ground termites from an area surrounding a structure. The apparatus is connected to a power source and includes first second sets of electrodes positioned in a ground area on opposing sides of the structure. A first lead line is connected between the first set of electrodes and the power source for supplying an electrical current to the first set of electrodes and a second lead line is connected between the second set of electrodes and the power source for supplying an electrical current to the second set of electrodes. The electrical current supplied to the first and second sets of electrodes is delivered to the ground in which the first and second sets of electrodes is positioned and flows through the ground between the first and second sets of electrodes forming a barrier region within which any termites will be electrocuted. The first and second sets of electrodes preferably include at least four electrodes.

Abstract: An apparatus and method utilizing a phase-locked high voltage, high-frequency generator or alternator capable of quasi-unlimited power output for feeding electric power into pest-infested earth via an electric conducting wire, for example termite infested ground Utilizing a conventional line power, the power source produces high energy pulses. The pulses are fed into an underground electric conducting wire for application at high voltages. The voltages penetrate the earth and electrocute and repel the nematodes and arthropods contained therein.
