Harris Diatomaceous Earth Food is a bag of 100% ground freshwater diatomaceous earth with no additives or fillers, plus a powder duster for puffing it into cracks and crevices. It is OMRI-listed for organic use and marketed as chemical free and safe around children and pets when used as directed. The draw is simplicity: one fine powder for crawling insects, dusted where they travel. Rivals often sell DE alone or in shaker bottles; Harris bundles the duster and leans on its food-grade, single-source story. Owners like the duster and the fine grind, but the powder is light and messy, and it must stay dry to work.
