Abstract: The present invention pertains to a method and apparatus for controlling fire ants using electrical and mechanical stimulus methods. A stimulating source is provided, that when activated, attracts the fire ants, causes the fire ants to cluster around the stimulating source, and agitates the fire ants to the point that ants from a common colony attack each other. An AC voltage may be used as the stimulating source.
