To apply powder insecticides, pesticides, fertilizers, or diatomaceous earth to plants, animals or building surfaces, you need the right tool for the job. Garden dusters help you control the spray of powder so you apply it exactly where it's needed. Whether your job is large or small, there are applicators that are designed to suit your budget and usage requirements. Dustin-Mizer's hand-cranked garden duster has a deflector to target the undersides of plant leaves and other hard-to-reach places. The Pest Pistol Mini Duster applies powder with the squeeze of your hand. And the Earthway Spritzer Duster Sprayer applies an even coating of both powder and liquid products.
