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

Both are food-grade freshwater diatomaceous earth with no chemical additives, so the real choice is size and how you plan to use it. The Harris 4 lb tub is easier to store and handle for indoor dusting, pet bedding and small garden jobs. The Pure DE 20 lb bag is the better pick for large areas, barns, coops and repeat outdoor treatments. Owners of both rate the powder fine and effective; the Harris tub reseals more cleanly, while the Pure DE bag needs a separate container once opened.

• Choose the Harris 4 lb if you want a small, resealable tub for indoor dusting, pet areas and spot treatments.
• Choose the Pure DE 20 lb if you are treating coops, barns, gardens or large floors and want one bulk bag.
