  • Pneumatic pesticide duster for treatment of structures
    Patent number: 4553698
    Abstract: A pneumatic pesticide duster for use in the application of pesticide dusts in structures. The apparatus comprises a dust reservoir, compressed air source, manually operated control valve and metallic discharge tube having an opening ranging in size up to about 3/4 inch capable of imparting an electrostatic charge to the expelled air/dust mixture such that dust is attracted to the walls of the structure and to insects therein. The apparatus is easily handled by one person while the amount of pesticide dispensed within the structure and the areas to which the pesticide is confined can be closely controlled.
