Diatomaceous earth aka Diatomite, is naturally occurring soft, siliceous sedimentary rock (amorphous silica) that is crumbled into fine off-white powder. The granular powder falls between the range of 3 μm to 200 μm and sometimes up to 1 mm making it an effective and versatile solution for soil improvement and water management in farming and gardening. The naturally porous, absorbent structure of food-grade DE is a versatile helpmate for your healthy home, gardens, and farms and is environmentally compatible.
Diatomaceous earth powders contain about 80-90% of silica. It is effective against a wide range of pests including insects and mites. It is the safest approach to kill insects by dehydrating them or drying them. While DE is safe and used as a deterrent for pests it holds the extra perk of drying up their climate, it's especially effective for exoskeletons like ants or roaches too. However, it doesn't reside, it flows through while capturing unwanted materials in with it. So this whole process ensures a balanced ecosystem in a horticultural setting.
