Abstract: A termite control system utilizing an underground tube associated with underground or ground contacting foundation components of a building with the tube having discharge openings by which an insecticide may be discharged into ground areas adjacent the foundation of a building or the like for control of subterranean termites. In one embodiment, the tube system is associated with a posted or pier construction supporting a wood or composite floor. In a second other embodiment, the tube system encircles a pole-type foundation or support. In a third embodiment of the invention, the tube system is associated with a retaining bearing wall which has backfill dirt associated therewith. In each embodiment, the tubes are provided with radial slits to discharge insecticide therefrom with at least one end of the tube or tubes extending to a position accessible from a point above ground level to enable insecticide to be pumped into the tubes under predetermined pressure.

Abstract: A process of installing a pipe system under an existing building constructed upon a concrete slab or other foundation not permitting access beneath the ground floor, for the purpose of periodic introduction of insecticide to control or eradicate subterranean termites or other such pests, comprising forming a substantially horizontal hole or accessway beneath the building slab or foundation, inserting a pipe through the formed hole, the pipe being made of a plastic or flexible material containing apertures for discharging the insecticide, the pipe being inserted in the hole or accessway by capping one end of the pipe and inserting a solid push rod into the pipe until the push rod contacts the capped end whereby the pipe can be pushed through the hole or accessway without lateral or vertical displacement.
