Questions and answers

What is food-grade diatomaceous earth used for?

It is used as a natural dewormer for dogs, cats, poultry and livestock, mixed into feed or given in water. It is also spread in pantries and gardens against insects. Food-grade is the only grade safe to ingest; pool grade is not.

Is this the same as pool-grade diatomaceous earth?

No. Pool grade is heat-treated, which turns much of the silica into crystalline form and makes it unsafe to eat or breathe. This brand's food-grade powder is uncalcined amorphous silica, intended for feed and household use.

How is it given to pets?

Common practice is to mix a small amount into wet food or water, often starting small and building up. Dosage depends on the animal's size and species, so check with a vet first, especially for cats and small dogs.

Does it come with a warranty or return policy?

Returns and guarantees are set by the individual store that ships the order, not by the brand. Check the seller's return window before buying, since policies differ between marketplaces and farm-supply retailers.

When does this brand go on sale?

Promotions tend to appear around spring gardening season and fall livestock deworming, plus general retail sale events. The page tracks each store's price history so you can see when a store has moved its price.

Are there DiatomaceousEarth discount codes?

Deal.ai checks what DiatomaceousEarth products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
