Patent ID: 7766255

Claim:
A method for applying an aqueous pesticide solution comprising: providing a system for the application of an aqueous pesticide solution; the system comprising: a motor and a pump combination wherein said pump is operable in the 1000-3000 pounds per square inch range with a desired flow rate of about 1.5 to about 2.5 gallons per minute; a reservoir for holding said aqueous pesticide solution to be dispersed in fluid communication with the pump with an inline filter upstream of said pump for filtering said aqueous pesticide solution flowing from said reservoir to said pump; means for regulating and monitoring an operating pressure of the system; a spray gun assembly in fluid communication with the means for regulating and monitoring the operating pressure of the system, wherein the spray gun assembly further includes a spray gun and a detachable nozzle assembly and the detachable nozzle assembly includes means for restricting the flow rate of said aqueous pesticide solution and said means for restricting the flow rate comprises a hollow elongate portion having a predetermined length sufficient for inserting through a pre-drilled hole of a building wall and spraying said aqueous pesticide solution inside said walls, the elongate portion further comprising a plurality of circumferentially off-set spaced-apart apertures through which the aqueous pesticide solution is capable of spraying at a 360 degree radius, wherein the circumferentially off-set spaced-apart apertures are at least 1 mm in diameter and the elongate portion has an inside diameter of about 2 to 3 mm in diameter; wherein the motor and pump combination operating at said 1000-3000 pounds per square inch range with said desired flow rate of about 1.5 to about 2.5 gallons per minute and said spray gun and detachable nozzle assembly are configured so as to atomize said aqueous pesticide solution being dispersed into droplets of between 1 to 30 microns, wherein an adhesion property of the dispersed aqueous pesticide solution is significantly enhanced by such configuration, and wherein the dispersed aqueous pesticide solution is hydro-kinetically charged when released from its hydrostatic state as said aqueous pesticide solution flows through the means for restricting the flow rate of said aqueous pesticide solution, and wherein a vortex is created from a release of the pressurized, hydrostatic aqueous pesticide solution so that a cyclonic phenomenon of vortical fog allows the spray gun said aqueous pesticide solution to spray past an absorbing surface or obstacle, and to apply an equal solution contact with an opposite side of said surface or obstacle and to provide an equal application of said sprayed solution to any odd angled or irregularly shaped surface or desired target that may not have a direct access; and spraying said aqueous pesticide solution where desired in said atomized state at said desired operating pressure of said 1000 to 3000 psi and at said desired flow rate of about ˜1.5 to 2.5 about gallons per minute.
