There a numerous benefits a pet can receive from a consistent dosage of DE. Pet owners who have given their pets DE have found their pet has improved coat, appetite, metabolism, and digestion. External: Fleas, Ticks and other insects have exoskeletons, rigid outer bodies, or shells. When these insects touch diatomaceous earth, the tiny abrasive particles damage their exoskeletons and cling to their bodies, absorbing the moisture until they dry up and perish. The particles may also kill some flea larvae, but they are ineffective against flea eggs or pupae. Adult fleas may die as quickly as four hours after contact with diatomaceous earth.
