Method and apparatus for controlling fire ants. A method is disclosed for controlling colonies of fire ants in the environment. The method includes first providing a stimulating source that, when activated, will attract fire ants to contact the stimulating source and become agitated to a point that ants from a common colony will attack each other. Thereafter, the stimulating source is activated to cause the fire ants to cluster around the stimulating source, become agitated, and attack each other. The stimulated fire ants then are urged into a tightly confined space to exacerbate the attack reaction.
