Biolink Diatom is a natural product made from the fossilised remains of ancient shell creatures. It can be used for the lasting control of insects and red mites in hen house's. Treatment should begin before any signs of red mite appear as once they are visible to the naked eye they are much harder to control. It can also be sprinkled in the chicken's dust bath to provide extra protection.
BioLink Diatom is now under European Law classed as a pesticide. We can no longer make any claims as a wormer.
All prices include VAT where applicable.
