40+ weeks protection.

How does it work?

Fossil Shield® is a unique silica based product that scratches red mites' outer waxy shell as they crawl through. This dries them out, controlling mite populations in a physical way.

The specialised Fossil Shield® formula means that it is more robust than pure diatom in humid shed environments, reducing coagulation, retaining its coarseness for longer.
