Plus, they’re just plain gross, right?!
Read how diatomaceous earth for dogs can get rid of fleas, ticks, and worms!

What Is Diatomaceous Earth?

Diatomaceous earth is a fantastic natural solution for pests such as fleas, ticks, and worms.

Diatomaceous earth is the fossilized, silica shells of microscopic algae.

It turns into an extremely fine powder that’s used as a preventative against various types of insects and other pests.

Is Diatomaceous Earth Safe For Dogs?

Often, the first question that comes up is can diatomaceous earth hurt my dog? The answer is that diatomaceous earth powder is very safe for dogs when given properly.

Using food grade quality DE powder in correct amounts is extremely safe and very beneficial! It’s also safe for use around children, unlike many conventional flea treatments. This is a high quality brand of diatomaceous earth that’s perfect!

What Does Diatomaceous Earth Do For Dogs?

Diatomaceous earth has so many benefits! What are the nutritional benefits of diatomaceous earth? Well, it contains many beneficial minerals when added to your dog’s food.

The calcium it contains can assist with bone formation, blood clotting, and nervous system function. The sodium helps maintain cellular fluid balance, aids in the transfer of nutrients, and helps process waste.

It also contains magnesium, which is key for many metabolic functions.

What Type Of Diatomaceous Earth Do I Need?

There are a few different types, but the one needed is labeled (very important!) ‘Food Grade’ quality.

It’s super affordable here on Amazon and has passed standards to be consumed in meals, which is necessary for natural deworming.

There are other quality levels available, such as ‘Pool Grade’, which is not recommended for use around kids or pets.

How Do I Feed It To My Dog to Kill Worms?

It’s super easy to treat your dog’s worms by feeding them diatomaceous earth. I simply mix it into Roxy & Rico’s food and stir it up.

The powder is very drying, and since it can irritate lungs if inhaled, it’s important to mix it in well. 

I scoop a bit directly into their bowls, and mix it with a bit of fish oil and hemp oil. The oils help moisten it a bit and makes it easier for them to eat without inhaling any.

How Does Diatomaceous Earth Work to Kill Fleas and Ticks?

Believe it or not, it doesn’t only need to be eaten to be a great natural flea and tick control!

Made from tiny, fossilized remains of aquatic organisms called diatoms; it causes insects to dry out and die by absorbing the oils and fats from the cuticle of the insect’s exoskeleton.

How To Use Diatomaceous Earth For Fleas

Wondering how to apply diatomaceous earth? Simply brush it onto your dog’s coat and to their sheets, bedding, and carpet as an effective means of flea control.

Treating your yard is also essential, otherwise those pests keep coming back. You can spread it in your yard; just sprinkle it when the grass is dry because it’s not effective when it gets very wet.

Be cautious of wind when spreading. Even though DE powder is safe and all-natural, as mentioned above, it can irritate lungs if inhaled. You may want to consider wearing a mask to avoid inhalation.

This is one of those tricks I wish I’d known 20 years ago when I moved into my first home and got my first dog, Jasmine! We struggled SO hard with managing fleas!

Every time we’d take her on a mini-vacation with us, we’d leave a flea bomb in the house, treat the yard with flea spray, and bring her to the groomers to do a flea dip. All that stuff is super unhealthy, and didn’t even work as well as diatomaceous earth has!

For example, my neighbors back then weren’t quite so motivated to manage their yards, so it was a constant battle against fleas. Now I know better, so I do better.

Treating the yard regularly means I haven’t even seen a flea in years, and I don’t have to evacuate the house while the poisons work to kill the pests!

Does Diatomaceous Earth Dry Out Dog Skin?

Diatomaceous earth can be a bit drying when applied too often. If you’re trying to actively kill fleas, brush it on no more than once a day.

Pay close attention to the condition of your dog’s skin and take a break if you notice the skin starting to look dry and flaky.

You can also add fish oil to your dog’s diet to help condition their skin. Learn more about the benefits of fish oil here!

How Long Does It Take For Diatomaceous Earth To Kill Fleas On Dogs?

Research shows it takes a few hours for fleas to make contact with diatomaceous earth and for it to start drying them out so they die off. The typical flea life cycle is 2-4 weeks.

Due to the different stages of the flea life cycle, it may take a few days for the fleas to die off, but the eggs may need additional time. You might need to vacuum a bit more often to pick up the fallen yuckies.

Does Diatomaceous Earth Kill Worms In Dogs? 

Diatomaceous Earth is fantastic for use against so many different types of worms. Much like with fleas, it works by creating microscopic cuts in the worms, so they dry out and die off.

Because worms have a longer life cycle than fleas, you’ll need to add it to your dog’s food for at least a month.

I add it to my dog’s food daily as a preventative. This allows them to get the full nutritional benefit of diatomaceous earth while also staying protected against worms.

What Types Of Worms Does Diatomaceous Earth Work Against?

Roundworms are the most common worms that a dog can get, as they spread so many different ways. Mothers can pass it to babies, or they can contract it by eating rodents or poop from other dogs with roundworms.

Whipworms, hookworms, and tapeworms are all other types of intestinal parasites that can be picked up from contaminated dirt that has been in contact with an affected dog’s poop. 

Even though diatomaceous earth is amazingly helpful at prevention and deworming, it’s important to have your dog tested periodically to ensure they’re not suffering from worms.

Even older dogs can be affected by worms, and there are often no symptoms. Since regularly adding diatomaceous earth powder to Roxy & Rico’s food, they’ve happily been worm-free at all their vet checkups! 

Here’s How Much Diatomaceous Earth To Give Your Dog Per Day:

Small Dogs and Puppies* – ½ tsp of food grade DE

Dogs under 50 lbs – 1 tsp of food grade DE

Dogs 50-100 lbs – 1 tbsp of food grade DE

Dogs over 100 lbs – 2 tbsp of food grade DE

*It is recommended to hold off on adding it to their diet until they move to solid food.

See how great diatomaceous earth is as a natural flea treatment and dewormer?! What’s your go-to strategy for getting rid of these yucky things?
