Pets: Our best friends come in all shapes and sizes. Protect them with Diatomaceous Earth. When lightly rubbed into their coats or dusted on their premises, it is very effective against fleas, ticks, lice, and other pests on pet dogs, cats, and birds. It can also be used as an organic wormer and will kill any worms or parasites the pets may have.
