The Eaton Hand Duster is absolutely the best bellows duster on the market. In addition it's the long time favorite of professionals who can't do without the device. This duster makes applying insecticide dusts and fine granular bait easy and accurate. This tool is a must when treating for ticks, carpenter ants, carpenter bees, German roaches or anywhere there are cracks and crevices to be treated. Remember that insects are at "home" in a crack where both walls of the crack touch (or almost) their body.
