Abstract:
1. A method for delivering a pesticide in a structure having an exterior facing, the method comprising: injecting the pesticide into a tubular conduit positioned adjacent an interior side of the exterior facing of the structure, the tubular conduit having a sidewall, a first end, a second end, and a plurality of pores extending through the sidewall of the tubular conduit, the tubular conduit constructed of an elastomeric material such that upon applying a positive internal pressure to the tubular conduit above a threshold pressure the pores of the tubular conduit are caused to open to permit the discharge of pesticide from the tubular conduit and upon removal of the positive internal pressure so that the internal pressure is below the threshold pressure the pores are caused to close, the pesticide being injected into the tubular conduit at a rate such that the internal pressure of the tubular conduit remains below the threshold pressure of the tubular conduit until the tubular conduit is substantially filled with the pesticide thereby preventing the pesticide from being discharged through the pores of the tubular conduit as the tubular conduit is being filled with the pesticide; and continuing to inject the pesticide into the tubular conduit so as to cause 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.
