Diatomaceous Earth

About

Diatomaceous earth is a naturally occurring, soft, siliceous sedimentary rock composed of the fossilized remains of diatoms, microscopic aquatic organisms. It is typically a fine white to off-white powder with a particle size ranging from 10 to 200 μm. This substance is rich in silica, making up about 80-90% of its composition, with smaller amounts of alumina and iron oxide. Diatomaceous earth is used in various applications, including as a filtration aid, mild abrasive, and mechanical insecticide. Its effectiveness as a pest control agent lies in its ability to dehydrate and damage the exoskeletons of insects, making it particularly useful against crawling pests like ants, slugs, and snails. Additionally, diatomaceous earth is used in health supplements, where its silica content is believed to support bone health and detoxification. It is also employed in industrial applications such as plastics, rubber, and as a component in some cat litters and dynamite. Overall, diatomaceous earth is a versatile and environmentally friendly substance with a wide range of uses.
