This bulb duster kit is what I needed, for my diatomaceous earth which I would hand sprinkle or use a dustpan and feather to dust areas with insect invasions which is quite messy and dustier than with a controlled tool. The build duster comes with a removable base so you can refill it as often as you need with a provided funnel and a scoop to put in a few scoops to fill. Blub duster comes with a handy storage bag, but it is not labeled well so you can relabel it with a fabric marker or keep it with your diatomaceous earth bag in a bin or bucket for easy identification of what it is for in the future. The bulb duster comes with a built-in cap to close when you are done using it, so nothing goes to waste and you can use the rest later.
Dust the insect DE around the home, gardens, indoor plants, and the perimeter without wasting too much product and create less dust than by doing by hand without tools. Keep the bulb stored away from children and or dump any remaining DE back into the original bag until the next use. Small children may be curious and pump this in their face or another child's face not knowing the consequences and could pose a choking hazard.
The tool does exactly what it needs to do. Though it is small, a little goes a long way, unless you are working on larger areas. DE is not included and is sold separately.
