ABSTRACT:
A dispenser or applicator for dry insecticide includes a container having a removable cover; the cover is attached to a lower end of an elongate handle having a hand grip at its top A partition inside the container is the floor of the insecticide container, with a skirt extending below the partition; insecticide is dispensed through apertures in the container floor. These apertures are normally closed by a spring-biased stopper disk having tapered fingers which protrude through the apertures; the stopper disk is moved to an open position by inertia when the container is struck against the ground, unblocking the apertures and allowing a measure of insecticide to escape before the stopper disk rebounds to its closed position. Walls of the so container housing extend below the apertures to form a skirt which prevents scattering or dispersal of the powder.
