Diatom (Diatomaceous Earth) is a 100% natural powder used on poultry and animals to eliminate internal worms and external parasites such as lice and fleas and to improve their general health. It can be used on all types of poultry as well as horses, pigs, sheep, goats, dogs and cats.Diatom and Poultry Shield can be purchased directly from Durham Hens or through our online shop.

How Diatom works
Diatom is a powder made from finely ground fossil particles which are microscopically sharp. These particles scratch through the waxy exoskeleton of insects causing them to dehydrate and die.

How to use Diatom
Is it safe?
Diatom is chemically inert so it is completely safe for eggs, meat and the food chain so there is no egg or meat withdrawal time. Diatom is approved by DEFRA and the Diatom that we sell is food grade. However, it is not for human consumption.

Other Benefits of adding Diatom to Animal Feed
Pack sizes available450g, 2kg, 5kg, 10kg and 15kg.
