Dr. Killigan's The Insect Buster - Large 14oz Bulb Duster for Diatomaceous Earth

Effortless, precise powder application with Dr. Killigan's The Insect Buster

Meet Dr. Killigan's The Insect Buster, a purpose-built tool designed for diatomaceous earth and other fine powders. Built for durability and precise control, this bulb duster makes dusting tasks cleaner and more predictable. With a thoughtful blend of materials and a smart design, you can target powder exactly where you want it, helping you work efficiently and with less mess.

Two sizes to fit every task

The Large INSECT BUSTER holds 14 oz of powder and feels comfortable for bigger hands and larger spaces. The Small INSECT BUSTER is 8 oz, compact and nimble for tight corners, shelves, or detail work. Having both sizes gives you flexibility to tailor your toolkit to the job at hand.

Durable, all-metal construction

There are no plastic parts in this design. The tool uses high-grade rubber, aluminum, and brass, delivering a sturdy feel and reliable performance over time. A funnel is included to help you fill the bulb duster quickly and cleanly, so you can get back to work without fuss.

Enhanced design for easy filling and smooth dusting

New improvements include a bigger funnel to reduce spillover and a larger tip opening to minimize clogs, plus a clear vinyl powder applicator tube that helps you reach around corners and behind obstacles. These refinements translate to less mess and more direct application where you want it.

Versatile and user-friendly

Natural and safe to handle during routine dusting, the Insect Buster delivers controlled, steady powder flow without the wobble or guesswork of smaller tools. Its design supports careful, targeted placement for a range of powder-based tasks.

How to use

Fill through the included funnel, prime the bulb, and apply the powder in the strategic places described in our guidelines. Hold at a comfortable angle and press with steady, measured force to achieve even coverage. Move slowly to ensure the powder lands where you intend.
