The present invention provides a method, apparatus and system for treating fire ant mounds. The invention comprises a pressure vessel for holding water and steam, a water heating coil for heating water and a steam heating coil for heating steam. A heat source contemporaneously heats the water heating coil, the steam heating coil and the pressure vessel. Steam is generated, superheated and is supplied to a probe for applying steam to fire ant mounds. A nozzle containing countersunken ports may be attached to the probe. A sliding hammer to aid insertion and extraction may be fixed to the probe. An articulated protective shroud attached to the probe remains in contact with the ant mound surface.
