Abstract: Systems and methods for rapidly atomizing and dispensing electrostatically atomized insecticides and similar low electrical conductivity active materials without the use of VOCs. The active materials are dispensed via insertion of a disposable cartridge in a dispensing apparatus. The dispensing apparatus is hand actuated and the exhausted cartridge is minimized to the size of a wad of chewing gum and it is doubly sealed to prevent any residual active material from leaking into the environment. Spray flow and configuration may be user selectable.
