1. An improved termiticide delivery system for delivery of termiticide to potential termite entry areas of the fill dirt underneath the foundation slab of a building at the edges and joints thereof, comprising:

  • an endless unbranched emitter circuit comprised of a length of flexible tubing having a plurality of apertures spaced at intervals along the wall thereof for emitting termiticide therethrough, said emitter circuit disposed atop and across the fill dirt under the foundation slab and vapor barrier of a building, at the perimeter edges of said slab and around the edges of all openings through and interruptions of said slab;

    a plurality of spiraling loops of said emitter circuit disposed around openings through said slab;

    a plurality of flexible open-ended trunk lines comprising unapertured tube means, each trunk line having an injection end and a delivery end, each delivery end thereof connected to and opening into said emitter circuit at spaced-apart intervals selected to provide even distribution of termiticide throughout said emitter circuit, said trunk lines running under said slab to a common location on the outside of an exterior wall of said building;

    a common receptacle box attached to said building wall and having a panel therein having a plurality of openings passing therethrough, and having the injection end of each of said trunk lines attached to said panel through one said opening therein;

    applicator means comprising a manifold having a plurality of open-ended delivery lines comprised of flexible tubing, each line having a first and a second end, each said first end thereof attached and opening into said manifold, and each said second end thereof having coupling means whereby it is removably connected to one of said tube end connectors and communicates through said connector with one of said trunk lines for transmittal of fluid from said manifold into said trunk line, said manifold further having an inlet for connection to a source of termiticide; and

    a pressurized source of fluid termiticide;

    whereby injecting a termiticide substance through said inlet, manifold, and delivery lines into said injection ends of said trunk lines attached to said panel provides redundant delivery of termiticide throughout said emitter circuit to the fill dirt underlying all edges and interruptions of, and openings through, said slab in an effective amount.
