Perma-Guard Diatomaceous Earth is certified by OMRI as an organic product. We believe it is the purest, highest grade Fossil Shell Flour you can purchase. Accept no imitations, our product arrives in the original package, sealed by the manufacturer. Why take risks buying DE that has been handled and repackaged by someone else?
The EPA has approved DE as an additive in feed and grains for use as an anti-caking agent and has exempted it from tolerance requirements as an inert, inactive ingredient in chemical pesticides. Any uses other than those presented here are strictly anecdotal reports of what our customers have used it for. We sell this product for the uses stated on the label only. Any other benefits it may provide are incidental.
