Diatomaceous Earth is a 100% natural product, prepared from the fossilised remains of ancient shell creatures so is totally inert and safe to humans and animals.
DE can be used on animals, pets and birds against external parasites (lice, fleas, mites), internal parasites (worms), and for general good health. It increases digestibility of the feed when added to feed rations at 1-2% so will save on feed, as less undigested feed passes through the large intestine as waste matter. Can also be used as a mineral supplement for all animals and birds.
DE works mechanically rather than chemically so no immunity can be built up. As the mite crawl through the DE dust to get to the hens at night, the microscopically sharp shards that make up DE scratch the mite's waxy shell, thus causing them to slowly dehydrate and die.
We advise wearing gloves and a dustmask when applying DE as in some cases it can be a skin irritant.
