Abstract: A method and an apparatus for repelling ants and other insects positions design flow of insulated DC current in design proximity to targeted areas (1), facilities, equipment and AC electrical devices occupied by or likely to be occupied by the ants and other insects. The apparatus includes a DC ant and insect repeller having an insulated electromagnet conductor wire (2) with electromagnetic windings (3) charged with predetermined flow of DC electricity. Charge of DC electricity is predetermined for causing cyclic heat of 140° F. from electrical resistance within a range of 50-to-90 ohms in the electromagnetic windings. A flow cycler (26) cycles current on-and-off to prevent the repeller from being a heater of a cold place or a heater in opposition to an air-conditioner or desirable weather temperature while also minimizing use of electricity for repelling the ants and other insects.
