What is Diatomaceous Earth?
Diatomaceous Earth is inert dust harvested from sediments at the bottom of oceans, lakes, and rivers around the globe. It comes from diatoms – a type of single-celled algae with microscopic, beautiful geometric shells made of silicon dioxide. Furthermore, over millennia, diatoms accumulate in aquatic sediments as fossils that can be harvested and dried into fine white dust, known as Diatomaceous Earth.
Diatomaceous Earth is a non-toxic, safe substance made up of crushed fossils of freshwater organisms and marine life. Moreover, crushed to a fine powder and observed through a microscope, the particles resemble bits of broken glass.
Composition of Diatomaceous Earth
Each deposit of diatomaceous earth is different, with varying blends of pure diatomaceous earth combined with other natural clays and minerals. Also, the diatoms in each deposit contain different amounts of silica, depending on the age of the deposit.
The species of diatom may also differ among deposits and is dependent upon the age and paleo-environment of the deposit. Moreover, the shape of a diatom is determined by its species.
Common Uses and Side Effects of Diatomaceous Earth
Internal parasites can be controlled by giving Diatomaceous Earth internally. It is very important to note that it must be food grade – the earth used in gardens and pool filters can damage your dog.
Additionally, Diatomaceous Earth can eliminate roundworms, whipworms, pinworms, and hookworms within seven days of being fed daily. To be most effective, DE 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.
When you accidentally inhale a large amount of DE, it can cause coughing and shortness of breath. It can also cause irritation if you unintentionally rub it to your eyes.
Can You Use Diatomaceous Earth as a Natural Alternative to Dewormers and Flea Treatment?
Since DE can be used as pest control, many of you may be wondering if you can use Diatomaceous Earth for fleas and deworming dogs?
Dog Deworming and Flea Allergy Dermatitis
Dog deworming is necessary for dogs to reduce parasites internally and externally. This practice can improve your pet’s health and can prevent the transmission of parasites to you and to your family members.
The vet recommends de-worming your puppies when they’re 2 to 3 weeks old. Since worms can pass from mother to puppies before or after birth (through their milk). Deworming can also treat hookworms, whipworms, roundworms, and other intestinal worms.
Flea Allergy Dermatitis (FAD) can cause and develop anemia or low blood cells in dogs, especially in newborn puppies. They can also experience weakness, rapid breathing, lethargy, and death if not cured. The most common symptoms of FAD are excessive scratching, biting around the tail and backside, scabs, and bumps on the neck or back.
Using Diatomaceous Earth as Dewormer And Flea Treatment
Most pet owners use Diatomaceous Earth powder as flea treatment and dewormer. Since DE is considered a natural and drug-free treatment, it’s usually fed in an exact amount (depending on your dog’s weight) to eliminate all intestinal worms and parasites.
Moreover, food-grade diatomaceous earth powder should be fed 7 days daily to catch all newly hatched parasites. But keep in mind that you can’t feed too much DE to prevent your pets from getting sicker or experiencing stomach problems.
External use after flea exposure can also be an effective way to get rid of flea problems. You can sprinkle the diatomaceous earth powder onto your dog’s coat and brush it through all their fur before and after walks. Make sure to cover or avoid sprinkling DE on your dog’s nose, mouth, and eyes. Also, avoid daily use of DE if your dog has dry skin.

Diatomaceous Earth vs Frontline, Panacur
Let’s be fair and objective: whether you decide to preventively treat your dogs (and cats) with DE or with the regular brands with their own formulas, the results will be positive.
Where Diatomaceous Earth clearly wins the battle, if not the war, is that it is completely natural and does not cause as of the latest researches, any allergy or any serious undesired side effect. Some breeds are allergic to some brands (Collies, for example, do not support ivermectin, present in many products) and they tend to also cost a lot of money when you sum it all up at the end of the year.
Many efficient products can act as tick and flea treatments but diatomaceous earth for dogs is a natural one, which can earn the favors of several organic-friendly dog owners.
