Harris Diatomaceous Earth Food Grade vs Harris Food Grade Diatomaceous Earth

Both are the same 100% freshwater food-grade diatomaceous earth from Harris; the real difference is the size and the duster. The 4 lb bag is the better buy for most households: more powder, far more owner feedback, and OMRI listed for organic use. The 2 lb bag with the included duster suits someone who wants a ready-to-apply kit for a small job. Reviewers of both rate them well; the larger bag simply has a longer track record.

• Choose the Harris 2 lb with duster if you want a small amount plus a duster in one box for spot treating a few areas.
• Choose the Harris 4 lb if you want the most powder for the money and a larger, better-reviewed supply for ongoing use.
