The microscopic sharp edges of these shells cut into the woodlice cuticle and absorb the body moisture, resulting in dehydration and death.

Oa2ki Diatomaceous Powder is proving to be an invaluable tool in the enlightened professional’s armoury as, unlike synthetic poisons, insects cannot build up a resistance to it. Best when applied using an insecticide Powder Duster.
