Food Grade Diatomaceous Earth 1 lb vs Pure DE Food Grade Diatomaceous Earth 20 lb

Both are food-grade freshwater diatomaceous earth from US deposits, so the real split is size and packaging. The 1 lb bag is a fine starter for a household trying DE in food, smoothies or a small pet routine, and its buyers rate it highly. The 20 lb Pure DE bag is the better pick if you are treating a yard, coop, barn or garden, where a small bag runs out fast. Neither is a strong insecticide product on its own; both are fine powders with a resealable-bag weakness.

• Choose the 1 lb Food Grade Diatomaceous Earth if you want a small, certified-organic food-grade supply for personal or pet use and prefer a bag you can finish before it clumps.
• Choose the Pure DE 20 lb if you are dusting a large area like a coop, barn, yard or garden and want one big bag instead of repeated small ones.
