  • Method and apparatus for killing subterranean insects
    Patent number: 5109629
    Abstract: A system (10) and method for killing ants in a subterranean colony (102) is disclosed. Liquid insecticide is vaporized in a fogging a vaporization chamber (23) by the exhaust of an internal combustion engine (14) such as that mounted on a lawn mower (12) or farm tractor. An insertion probe (30) having exhaust holes (36) is connected to an output of the vaporization chamber by a flexible hose (24). In operation, the probe is inserted into the subterranean colony (102), whereby vaporized insecticide is applied down in the colony. Such vaporized insecticide travels through passages to various "rooms" of the colony, thereby contacting ants in all parts of the colony.
