I’ve written about how I use Diatomaceous Earth as one of three ingredients in my “3 Ingredient Homemade Organic Flea Powder Recipe“, so you may want to review that article and then touch back to this page.


I like Diatomaceous Earth for three reasons, it’s organic, it’s safe on and around pets and humans, and it kills all insects perfectly. Some people sprinkle Diatomaceous Earth on their pet’s food, because it will kill parasites in their intestinal tract.

According to Dog Health by lowchensaustralia.com, a daily Diatomaceous Earth dose in food or water can be given to kill: Pinworms, Roundworms, Hookworms, Whipworms

Daily Doses for Pets:
Kittens 1/2 teaspoon
Cats 1 teaspoon
Puppies 1/2 to 1 teaspoon
Adult Dogs 1 teaspoon for each 17 pounds of weight.
Continue the dosing for a full 60 days if parasites are present.

A Word of Caution!

Make sure you purchase Food Grade Diatomaceous Earth without enhanced chemical pesticides. Diatomaceous Earth is often used in swimming pool filters, and that blend contains carcinogenic properties due to it’s processing protocol. Be gentle when working Diatomaceous Earth into your pet’s fur. Do it slowly and gently, to avoid any of the dust from the Diatomaceous Earth settling in your pet’s eyes or nose.


The primary organic ingredient in this Flea treatment recipe is Food Grade Diatomaceous Earth, along with organic Neem Powder and organic Yarrow Powder.

The Diatomaceous Earth kills the Fleas, as well as basically all insects such as spiders, ants, termites, earwigs, silverfish, bedbugs, etc, etc, etc.

The Neem powder has moisturizing properties that help to nourish dry skin, along with anti-bacterial properties that prevent infection. Diatomaceous Earth tends to be drying to the skin, so including Neem powder in this recipe benefits your pet – to ensure they’re skin doesn’t get too dry and start to bother them.

The Yarrow powder has healing and anti-inflammatory properties, and soothes irritated skin. The Yarrow works to soothe areas of Flea bites, and really helps to heal areas where a pet will scratch themselves.


With these three ingredients working together – you’re packing a punch to Kill Fleas, Keep Fleas away, Soothe/Heal Flea bites, and keep your pet’s skin healthy.


These are the organic ingredients I buy from amazon: Food Grade Diatomaceous Earth, Neem Powder (or this Organic Neem Powder), and Organic Yarrow Flowers Powder.


I use a larger size cosmetic brush to apply the mixture, and work it into my dog’s skin, behind her ears, under her tail, on her belly, in her armpits, and really give her good protection from Fleas every week, and after she comes home from her spa day at the groomer each month.


I actually use Food Grade Diatomaceous Earth a lot around the house and in the garage. It works perfectly to keep away ants and spiders – two things I do Not want to find in my house. When we had remodeling done, and walls were exposed, I use a poufer – actually called a “Powder Duster” – and applied a very light coasting of the Diatomaceous Earth on all the studs and always along the trim of walls. Here’s an example of Food Grade Diatomaceous Earth I’ve used that comes with the Powder Duster.

Diatomaceous Earth never degrades, so when used inside walls to repel insects, it’s extremely effective. As long as it doesn’t get wet, it can last forever to keep bugs away. In the garage, I drilled very small holes in the walls, and ‘poufed’ the Diatomaceous Earth into the walls, sealed with drywall mud, primed and painted over the holes. It’s just for my own peace of mind. I am not a bug person, and it really just makes me feel better to do these type of things.
