A Hand Duster is the Pest Professional’s Number 1 Tool, when it comes to applying crack and crevice treatments of fine dust products into cracks and crevices.
To use the duster, fill the rubber container (bellows) half-way with an insecticide dust product such as Delta Dust, PyGanic, ECO Pco D-X, Borid Dust, Timbor Professional or any other similar insecticide dust. Then tilt the duster sideways and gently squeeze, you should have a mixture of dust and air come out of the tube. Remember to apply dust evenly and lightly. A little goes a long way.
