How Can I Treat and Prevent Heartworm Naturally?

Almost every day I get asked the question of whether you can use something natural to treat and prevent Heartworm in pets.

The Benefits Of Diatomaceous Earth For Dogs

Diatomaceous Earth is a dirt cheap way to control external and internal parasites in your dog.Diatomaceous Earth is a non-toxic, safe substance made up from crushed fossils of freshwater organisms and marine life. Crushed to a fine powder and observed through a microscope, the particles resemble bits of broken glass. Diatomacous Earth is deadly to any insect yet completely harmless to animals.

Diatomaceous Earth’s mode of action for insect and parasite control is strictly mechanical. The microscopically sharp edges contact the insect or parasite, and pierce their protective coating, so they soon dehydrate and die. The larvae is affected in the same way.

The Benefits Of Diatomaceous Earth For Dogs

Internal parasites can be controlled by giving Diatomaceous Earth internally. It is very important to note that it must be food grade like ours! – the D.E. earth used in gardens and pool filters can damage your dog. Diatomaceous Earth can eliminate roundworms, whipworms, pinworms, and hookworms within seven days of being fed daily.  It can also be used to treat and prevent Heart worm according to Dogs’s Naturally Magazine. To be most effective, Diatomaceous Earth should be fed for at least 30 days, to catch all newly hatching eggs or the cycling of the worms through the lungs and back to the stomach.

Another use for Diatomaceous Earth is the control of external parasites and flies. This is achieved by dusting your dog with Diatomaceous Earth, along with his bedding area and surrounding carpeted areas. We recommend “sealing in” the D.E. with our “Flea & Tick” blend for double armor!!!

The Dog Channel also has a great article about D.E. and the treatment of heart worm.

Wolf Creek Ranch also covers this issue in the their article regarding D. E.

Here’s another great article about the benefits of D.E. and heart worm.

Other Uses

Diatomaceous Earth has also been reported in scientific literature to absorb methyl mercury, e-coli, endotoxins, viruses, organophosphate pesticide residues, drug resides, and protein, perhaps even the proteinaceous toxins produced by some intestinal infections. Given this, Diatomaceous Earth is very useful as a detox solution, digestive aid and colon cleanser.


For dogs, use one tablespoon per day of food grade Diatomaceous Earth in his food for dogs over 55 lbs. and one teaspoon per day for small dogs and puppies. For external parasite control, simply rub the powder at full strength into the coat for fleas and sprinkle on bedding.

It is important to note that no official scientific studies have been documented on the effectiveness of D.E. and heart worm because the pharmaceutical companies have nothing to gain from those discoveries. So most of the data we have was obtained by Holistic Veterinarians who have conducted their own private testing. 

Also, keep in mind, mosquitos are the major carrier or heart worm, so its important that you do whatever you can to repel these pests with a product like our All-natural Flea & Tick Bundle!
