Organic D/Earth Powder
Thomas Labs Organic D/Earth is a non-toxic, safe mineral of crushed fossils, pure diatomaceous earth, that can be given in food daily as a supplement or to control internal parasites. D/Earth is also used to control external pests when sprinkled in kennels and bedding areas.
Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.
Diatomaceous earth is a remarkable substance that actually dries out the waxy outer layer of fleas so they dehydrate and eventually die.
feeding of food grade diatomaceous earth helps eliminate most internal
worms, including roundworms, pin worms, tapeworms. When fed daily,
it's excellent in keeping fly concentrations down. Since food grade
diatomaceous earth is eliminated from the body exactly the way it went
in, it helps reduce the manure odor and kills flies that come in contact
Kennel Use: Sprinkle around kennel or bedding areas where there is a high concentration of parasites.
