Thomas Labratories Diatomaceous Earth Shaker, 12-Ounce
D.E. (Diatomaceous Earth) is a non-toxic, safe substance made up from fossils of freshwater organisms and crushed to a fine powder. The powder particles resemble bits of broken glass when observed thru a microscope. Deadly to any insect or larvae, D.E. scratches the insect's waxy outer shell causing death by dehydration. D.E is completely harmless to all animals, fish, birds or in food. This makes D.E. (Diatomaceous Earth) an excellent natural topical dusting powder for animals with fleas, ticks, lice and other external pests. D.E. (Diatomaceous Earth) can also be used as a oral nutritional supplement in feed or fed straight during parasite season for animals with skin and coat needs associated with internal parasites.
