Abstract: A peripheral termiticide delivery system of flexible apertured tubing is provided for injection under pressure of termiticide between the exterior walls of a building and its exterior coating. The tubing preferably has flanges extending therefrom whereby it is affixed to the walls around the building above ground level, and the apertures are protected from clogging by coating material. Injection ports for injection of termiticide into the tubing are disposed at intervals along the tubing, which ports are adapted to extend outside the exterior surfacing materials. Termiticide is injected under pressure into each port until all sections of tubing are filled to overflowing and termiticide exiting the apertures soaks the adjacent wall surfaces and runs down into the adjacent soil, creating a termite barrier. The system may be installed after construction by cutting a channel through the exterior coating, inserting the tubing into the channel and then reapplying exterior coating.

Abstract: A system for reapplication of termiticide substance to the fill dirt underlying the foundation slab of a building at potential termite entry points is installed prior to pouring the slab. The system has a single, endless unbranched emitter circuit of apertured, flexible tubing, disposed upon the fill dirt at the perimeter edges of the slab and around the openings in the slab where bundles of utility connections penetrate the slab. The emitter circuit is fed by a redundancy of open-ended unperforated trunk lines, connected to the emitter circuit at spaced apart intervals, to equalize distribution of termiticide to all soil areas adjacent the emitter circuit, the despite possible breaks or clogging in one or more trunk lines or in the emitter circuit. The trunk lines run from the emitter circuit under the slab, are bundled, and run through a single channel drilled horizontally through a foundation block, to the outside of an exterior wall of the building.
