Diatomaceous earth is a natural pet-friendly flea remedy applied every two to three days to a cat's coat. Because diatomaceous earth kills fleas by absorbing the oils and fats from their exoskeleton, the process can take up to three weeks.
- Dust a towel with diatomaceous earth
Place the powder in a towel, which allows for more thorough application while simultaneously restraining your cat.
- Apply the powder to your cat's fur
Work the powder into your cat's fur, starting with the base of the tail and moving forward along the spine. Be sure to apply the powder on the skin, pushing the fur aside if need be. Pay special attention to the armpits, paws, toes and the top of the head. Avoid getting any powder on your cat's face. Gently wash it clean to prevent irritation.
- Break the flea life cycle
Use a flea comb to remove adult fleas and eggs and to check on the progress of the treatment. Treat your cat's bedding with diatomaceous earth as well to kill any fleas residing there. Inspect any other favored areas for signs of infestation, dusting them as necessary with the powder.
- Prevent future flea infestations
Apply diatomaceous earth to your cat's coat monthly. The powder also serves as a natural flea repellent.
