Diatomaceous Earth is a fine powder also known as silicon dioxide, consists of aquatic microrganisms.
As the insects crawl over the fine powder, their waxy outer protection is scratched, causing them to dehydrate and die. Diatomaceous Earth is non-toxic to human and pets and will remain active as long as it is kept dry.
Diatomaceous Earth is an odourless non-staining powder. Can be used safely around dogs, cats, small animals, fish and birds. An excellent product for your kitty-litter box.
For indoor use, lightly coat the infested area where fleas, ticks and mites are found. Vacuum after 4 days and reapply.
