Diatomaceous Earth (codex grade) is a natural insecticide that has been used since well before 1900 to fend off all sorts of insects from grain/flour. Diatomaceous Earth makes a very effective natural insecticide. The insecticidal quality of Diatomaceous earth is due to the razor sharp edges of the diatom remains. When diatomaceous earth comes in contact with the insects, the sharp edges lacerate the bugs waxy exoskeleton and then the powdery diatomaceous earth absorbs the body fluids causing death from dehydration. Diatomaceous Earth works in a purely physical/mechanical manner, not ‘chemical’ and thus has no chemical toxicity. Therefore parasites don’t build up a tolerance/immunity to it.

The mineral and silica content seems to increase feed utilization. Reported to kill 75% of flies and fleas that come in contact with it within 72 hrs. Mixed with grains at a ratio of 2% keeps out pests. Diatomaceous earth is excellent for eliminating ants, aphids, flea beetles, fleas, earwigs, sowbugs, mange mites, flys, ticks etc.

Known worldwide for its extremely pure quality, our "Food Grade" Diatomaceous Earth (DE) is an eco-friendly naturally organic material from the purest fresh water source. Diatomaceous Earth is the fossilized remains of microscopic shells created by one-celled plants called Diatoms. Not all deposits of diatomaceous earth or the diatoms present in those deposits are the same. The shape of the diatom must be tubular with holes on the walls. It is important to have a consistent shape diatom without any unwanted sediment and it must be fresh water because the diatoms form a harder shell and is less fragile than those in salt water. Salt-water deposits contain a mix of diatom species. These deposits shapes and sediments are inconsistent, making them unusable for our products.

Of the 600 deposits in the US only four are considered "food grade" by FDA standards. Other food grade deposits may contain higher amounts of sediment and clay that make them less effective. After analysing many other "Food Grade" deposits we are satisfied that our Diatomaceous Earth Shell Flour is the purest form of Diatomaceous Earth.
