Harris Food Grade Diatomaceous Earth is a 4 lb bag of ground freshwater diatomite, a fine abrasive powder used around the home and garden. It is listed with the Organic Research Minerals Institute, which matters to shoppers who want a simple, non-chemical option. It suits people treating cracks, crevices, pet areas and garden beds where a desiccant dust is wanted. Against liquid sprays it needs dry conditions and patience, and it is not a knockdown insecticide.
