Perma-Guard Diatomaceous Earth (10 lb)

Perma-Guard Diatomaceous Earth is a natural, food-grade product made from fossilized remains of microscopic aquatic plants called diatoms. These plants inhabit waters across the globe, forming the base of the aquatic food chain much like grass does for land animals. Over millennia, their silica-based shells have accumulated into deposits that are carefully milled into a fine powder for agricultural and household use.

Diatomaceous Earth is a fossilized deposit of microscopic shells created by one-celled plants called Diatoms. These plants inhabit all the waters of the earth, and serve as the basic food for aquatic life, just as grass is the basic food for land animals.

In gardening and farming, Perma-Guard Diatomaceous Earth offers an effective, chemical-free method for pest control. Its microscopic particles physically damage the exoskeletons of insects such as ants, aphids, and flea beetles, causing them to dehydrate without the use of synthetic pesticides. It can be safely applied in vegetable gardens, orchards, greenhouses, and around livestock. Its porous structure also benefits soil health by improving aeration, enhancing moisture retention, and aiding nutrient availability—fostering strong root growth and resilient plants.

For animal husbandry, it can be mixed into feed at a rate not to exceed 2% by weight of the total ration. This helps reduce moisture in feed, minimize clumping, and discourage internal parasites naturally. A versatile tool for organic and sustainable growers, Perma-Guard Diatomaceous Earth supports healthy plants, productive gardens, and a balanced farm ecosystem.
