Harris Diatomaceous Earth Food Grade vs Pure DE Food Grade Diatomaceous Earth 20 lb

Both are 100% food-grade diatomaceous earth; the real split is size and extras. The Harris 2 lb bag ships with a powder duster, so it suits a first-time buyer treating a few cabinets, pets or a small coop. The Pure DE 20 lb bag is ten times the volume with no applicator, so it suits repeat users with a large coop, barn or garden who already own a duster. Owners of both rate the powder fine and effective; Harris draws praise for the included duster, Pure DE for the Oregon freshwater source and bulk size.

• Choose the Harris 2 lb if you want a small bag with a duster included for spot treating pets, cabinets or a small flock.
• Choose the Pure DE 20 lb if you already have a duster and need a large supply for a coop, barn or garden.
