Safe for human and pet use, our DE is free from all additives, certified organic, professionally packaged, and is the only official diatomaceous earth health supplement on the market. Where does DE come from? Diatomaceous earth is made up of tiny fossilized diatoms (plankton) that have accumulated over millennia in fresh water lakes. These pure deposits are mined and ground into a fine powder that is naturally high in silica and other minerals. It is this chalky white powder that we call diatomaceous earth. Use diatomaceous earth powder for fleas to help keep pet pests under control. This natural, absorbent stain, odor and flea powder is easy to apply.
