Harris Diatomaceous Earth Insect Killer

Diatomaceous earth is a natural mineral powder that works mechanically rather than chemically. When crawling insects come into contact with the powder, it absorbs the oils from their exoskeleton, causing them to dehydrate and die.

Because it is a natural, non-toxic mineral, it is generally considered safer than synthetic chemical sprays. However, you should still avoid breathing in the dust during application and keep pets and children away from the area until the powder has settled into cracks and crevices.

Yes, the effectiveness of diatomaceous earth relies on it staying dry. If the powder becomes wet or damp, it loses its ability to dehydrate insects, so you will need to reapply it once the area is completely dry.

The included duster is designed for precision, so focus on cracks, crevices, baseboards, behind appliances, and other hidden areas where insects travel or nest. A light, visible dusting is more effective than a thick pile, which insects may simply walk around.

Since this is a mechanical solution rather than a fast-acting poison, it is not an instant knockdown product. It can take several days for the powder to effectively dehydrate the insect population, so patience is key.
