How DE Works

  • Physical Action: DE’s sharp particles physically damage the pests’ protective coatings, leading to dehydration and death.
  • Safe for Pets: Unlike chemical pesticides, DE is non-toxic to dogs when used as directed, making it a safer alternative for pest control.

Pet owners appreciate DE for its dual action; not only does it deter external pests, but it also aids in the control of internal parasites when ingested. The recommended approach involves adding food-grade DE to the dog’s diet, which can help eliminate worms and other parasites from the digestive tract.

According to Julia Henriques:

  • “Diatomaceous earth can eliminate roundworms, whipworms, pinworms, and hookworms in your dog. It can work in as little as 7 days of daily feeding.”
  • “Note: Diatomaceous earth works for intestinal worms. It will not kill heartworms.”

Application Tips

  • External Use: For flea control, dust the dog’s coat lightly with DE, avoiding the eyes and nose.
  • Internal Use: Mix the appropriate dosage of DE with the dog’s food to fight internal parasites.

Despite its benefits, it’s crucial for pet owners to source human-grade DE and follow recommended dosages to avoid potential risks. Regular use, especially during peak flea and worm seasons, can significantly reduce the likelihood of infestations, contributing to a healthier, more comfortable life for dogs.
