DE-NAT

Natural Barrier. Pure Protection.

DE‑NAT is an Australian‑sourced brand specialising in diatomaceous earth (DE) pest barriers. Their premium, fine-grain and granular DE products create a physical shield on growing media that naturally deters fungus gnats, mites, and other substrate pests, no chemicals required.

Beyond pest control, DE‑NAT enhances substrate aeration, porosity, temperature regulation, and provides a trace source of silica, also making it a natural alternative to perlite in mixes.

At Hydro Oasis, we recommend DE‑NAT for its chemical-free protection, substrate benefits, and proven effectiveness. Easy to apply and entirely pet-safe, it’s the go-to solution for growers seeking clean, reliable pest management.
