ABSTRACT:
A method for delivering a pesticide adjacent a foundation of a structure is provided. The method includes injecting the pesticide into a tubular conduit positioned proximate to the foundation of the structure. The pesticide is injected into the tubular conduit at a rate such that the internal pressure of the tubular conduit remains below a threshold pressure of the tubular conduit until the tubular conduit is substantially filled with the pesticide thereby preventing the pesticide from being discharged through pores of the tubular conduit as the tubular conduit is being filled with the pesticide. Continued injection of pesticide into the tubular conduit causes the tubular conduit to be uniformly pressurized above the threshold pressure of the tubular conduit along the length of the tubular conduit to cause the pesticide to be discharged from the tubular conduit at a substantially uniform rate along the length of the tubular conduit and form a chemical barrier against the infestation of pests into the structure through openings formed in the foundation of the structure.
