Aim at your target area and gently squeeze the bulb.


Take back your peace from unwelcome insects.

I use insect powder a lot to control fungus gnats in my houseplants, and this duster is the best applicator I've used. I've begun to use it around windows and door frames to keep bugs at bay in the warmer months, and it seems to be working really well, which is a feat in Florida. The extension pole on this duster makes dusting around the house super easy. I can get into the back corners of cabinets, under furniture, and into nooks and crannies with ease.
