Abstract: A hand-portable fire ant killing device for vaporizing liquid resmethrin and infusing vaporized resmethrin throughout a fire ant mound on ground includes a dome, sized for fitting over a fire ant mound to be exterminated, having a top and an interconnected lower lip for contacting the ground entirely around the fire ant mound and for forming a closed interior chamber above the ant mound, a lightweight, high temperature gas discharging device which is mounted on the top of the dome, a high temperature gas discharging manifold directed into the closed interior chamber between the dome and the ant mound, a tank for containing resmethrin without pressurization which is mounted on top of the dome and a metering chamber and conduit which are connected for delivering a predetermined amount of resmethrin by a force overcoming the pressure in the dome for vaporization therein.
