Ozz Organics Diatomaceous Earth is a 100% natural worming and parasite management powder made from fossilised marine algae. With no harsh chemicals involved, it's effective against a broad range of intestinal worms including roundworms, pinworms, threadworms, and hookworms, and can be used across dogs, cats, chickens, and horses.

Diatomaceous earth works mechanically rather than chemically — the microscopic silica particles damage the outer membranes of soft-bodied parasites on contact, causing them to dehydrate. Because there's no chemical mechanism of action, parasites cannot develop resistance to it over time, making it a reliable long-term strategy for natural parasite management.

Ozz Organics DE mixes directly into food with minimal taste impact. The fine powder blends easily and can also be used externally as a dust to help manage mites and external parasites. Available in multiple pack sizes to suit individual pets through to farm and flock management needs.
