Abstract: Method and apparatus for eradicating insects in both a below ground and above ground environment. The device includes a main shaft having a bore therein and a two-piece clamshell on one end for insertion into the insect bed and on the other end a main body which includes a hand grip and a lever for releasing the gas which is held in a separate gas cylinder. The gas flows through a gas tube from the gas cylinder through the main shaft and then out the clamshell end of the main shaft into an insect bed. Two inert gases are used to displace the air in the insect colony wherein the two inert gases are argon and helium. The argon gas is used for underground applications and the helium gas is used for above ground and underground above grade applications. The two-piece clamshell is used for insertion into the ground where it is opened thereby allowing the gas to escape from the gas tube contained inside the clamshell.
