Harris Diatomaceous Earth is a 100% freshwater diatomaceous earth powder sold in 2 lb bags, here as a 12-pack. It is food-grade, so the same powder works as an anti-caking feed additive for animals and as a mechanical pest control dust for crawling insects. It is odorless and fine, and users say it spreads easily with a duster. Against liquid or bait insecticides it is slower and needs dry conditions, but it leaves no chemical residue and is safe around pets and food areas when used as directed.
