Dr. Killigan's Bulb Duster – The Insect Buster Large 14oz, Metal Refillable Powder Applicator for Precise Non-Toxic DE

Dr. Killigan's The Insect Buster is a non-toxic 14oz bulb duster, sprayer, applicator and dispenser designed to apply diatomaceous earth and other powders precisely and safely.

Whether you use food-grade diatomaceous earth, boric powder, or other dry pest control powders, this large Insect Buster gives you controlled, no-waste application. Built from metal, rubber, and brass (no plastic parts), the tool is designed to be durable and refillable. It includes a funnel and a clear vinyl applicator tube to reach narrow gaps so you can treat baseboards, attics, crawlspaces, and outdoor cracks with better accuracy than shaking from the bag.

How does the Insect Buster make powder application easier?

The Insect Buster converts loose powder into an even, directed puff so you can place material exactly where it will work best. The bulb creates consistent pressure, while the improved tip and larger funnel reduce clogging and mess during filling.

• Large 14oz capacity for fewer refills and longer jobs
• Wide funnel makes filling quick and tidy
• Enlarged tip opening decreases blockages
• Clear vinyl tube reaches tight corners and crevices

Is this duster safe to use with food-grade diatomaceous earth?

Yes — the Insect Buster is made to handle inert powders such as food-grade diatomaceous earth without reacting with the materials. Because it has no plastic internals, it resists wear from abrasive powders and remains dependable over many uses.

• All-metal and high-grade rubber construction avoids plastic wear
• Compatible with food-grade DE and similar inert powders
• Funnel and wide opening reduce spill risk during refills
• Clear tube lets you see powder flow in tight spots

What improvements were made compared with older bulb dusters?

This model focuses on bigger openings and better access. The redesigned funnel and larger tip reduce clogging and mess, while the vinyl applicator tube and robust components extend useful life and make precise placement simpler.

• Bigger funnel for faster, less-mess filling
• Larger tip opening to minimize clogs
• Clear applicator tubing for visibility in narrow gaps
• Durable brass, aluminum and rubber parts for longevity

Where should I use the 14oz Insect Buster around my home?

The large size is intended for bigger hands and larger jobs where frequent refills would slow you down. Use it in attics, basements, garages, around foundations, in wall voids, and along longer runs of baseboard where consistent coverage matters.

• Attics, crawlspaces and basements for perimeter treatments
• Garage and shed corners where insects hide
• Along foundations and window sills for outdoor barrier work
• Baseboards, gaps and voids using the clear applicator tubing

Who is this for: The large 14oz Dr. Killigan's Insect Buster is aimed at homeowners, DIY pest-control users, property managers and hobbyists who prefer a reusable, non-toxic applicator for diatomaceous earth and similar powders. If you handle larger areas, want a rugged, refillable tool built without plastic internals, and need better reach into tight spaces, this tool is designed to make powder application faster, cleaner and more precise.
