Diatomaceous Earth for Fleas on Cats: Everything You Need to Know in 2021

If you are in search of a natural way to prevent feline fleas and other parasites, diatomaceous earth is what you need. For a better part of history, human beings have been leveraging the power of this natural compound to keep disease-causing and bloodsucking insects from themselves and their pets. That said, what exactly is diatomaceous earth? How does it work and how to use it?

My name is Nora, and today I am going to answer these questions to ensure you grasp everything there is on diatomaceous earth for fleas on cats. So, let’s start with the basics.

What Is Diatomaceous Earth?

Diatomaceous earth or DE is the fossilized remains of small organisms that inhabit water bodies. At studies, we call these organisms diatoms. Over centuries, these creatures pile up in aquatic bodies such as lakes, streams, oceans, and so forth. Silica that also makes up at least 26 percent of the crust of the planet is what constitutes the skeletons of diatoms.

As these fossils keep accumulating at the bottom of water bodies, they turn into another silica compound referred to as silicon dioxide. It is formed when silica combines with water and oxygen. Thus, we got to DE. This silicon dioxide is the main component in DE and can be accessed from the bottom of aquatic bodies. It is used for insecticides; thus, works great for pest control.

How Diatomaceous Earth Works

When ground to a fine powder, DE is still quite abrasive, especially to small organisms such as pests and parasites. It readily penetrates the exoskeleton of these small creatures dehydrating them and stripping them of essential fats and oils necessary for their survival. In turn, they dry up and die. At the same time, DE doesn’t affect bigger creatures, such as cats and other animals. That said, you can use diatomaceous earth for flea control on your feline every fortnight to protect it from fleas, ticks, hookworms, and other parasites. It is a naturally occurring pest control substance.

Diatomaceous Earth Food Grade

To rid your cat of internal parasites, add food grade DE to your feline’s food. I use Diatomaceous Earth Food Grade to assist in combating hookworms, pinworms, tapeworms, whipworms, and roundworms. The product is effective.

Grandpas Diatomaceous Earth for Fleas

Apart from that, I have used Grandpas diatomaceous earth for fleas and found it to be great at eliminating these stubborn pests. To kill external parasites, use diatomaceous earth for fleas and ticks as a powder to dust on the skin of your feline. Nonetheless, be careful not to get diatomaceous earth powder for fleas near your feline’s mouth, nose, or eyes as the substance is still abrasive.

HARRIS Diatomaceous Earth Food Grade

You can try Harris diatomaceous earth for fleas as it is listed as food grade on the packaging and is made from 100% natural freshwater DE. It comes with a powder duster that will help you apply the product efficiently. And it’s definitely a top-rated diatomaceous earth safer brand for fleas in the market right now.

Red Lake Earth Diatomaceous Earth with Calcium Bentonite

Also, I would recommend a Red Lake earth diatomaceous earth with calcium bentonite for fleas. You can spread it around your pet’s favorite areas and even add it as a supplement in your cat’s meal to get rid of parasites.

How To Use Diatomaceous Earth For Fleas?

Now to the important part, namely how to apply diatomaceous earth for fleas. Follow this simple guide on how to use DE effectively to rid your felines of parasites:

1Take note of the places where your feline likes to lay at home. It can be a kennel, under a sofa, a rug, or a pillow. These places are where you should generously apply diatomaceous earth on pets for fleas.
2Firstly, vacuum these places to get rid of flea eggs. It is because diatomaceous earth for killing fleas does not affect the eggs.
3Spread DE in the vacuumed areas. Do this effectively by using a sieve, sock tied on one end, or DE dusters. Note, DE works best when the place is dry; therefore, ensure there is no dampness in the region.
4How long to leave diatomaceous earth on carpet for fleas? Let the DE stay in the areas you have applied it for as long as possible. A minimum of two weeks is ideal.
5Apply diatomaceous earth on cats for flea control to the feline skin, making sure it comes into contact with the skin. If it only stays on the fur, it won’t work as expected. Be sure to talk to a veterinarian if you need help on how to apply diatomaceous earth to cats for fleas for the first time.
6Re-apply the DE next days on your feline until you see that there is a decline in flea infestation. After that, you can switch to a weekly application.
7After several weeks, vacuum all corners and places with DE. This way, you’ll get rid of remaining fleas and their eggs, thus, disrupting their lifecycle.

This is how to apply diatomaceous earth to cats. Nonetheless, be sure to talk to a certified veterinarian to get information on how to use diatomaceous earth for fleas in house. By learning how to use diatomaceous earth for flea control from an expert, you can ensure the safety and well-being of your feline companion.

Diatomaceous Earth for Flea Control in House: Tackling an Infestation

In its use as a pesticide, DE has proven to be effective in preventing and controlling fleas on pets. When finely-grounded, it pierces insects’ exoskeletons and works its way dehydrating them. Apart from pets, you can also use diatomaceous earth on carpets for fleas. However, applying this product to deal with an infestation in your home will be different from how you use it on your cat.

So, how do you use diatomaceous earth for fleas that have infested your home? Start by applying the substance daily everywhere the fleas are present until you begin to see changes. Once the infestation has died down a bit, you can space out your applications to once every week for prevention against another infestation. Ensure you pay extra attention to areas where your pet likes to sleep (bed, kennel, rug, pillow, etc.) and hang around.

Use Harris Diatomaceous Earth Powder Dust

For easy application, you can use the Harris Diatomaceous Earth Powder Duster. It will help you spread the powder evenly, and it doesn’t clog easily. It’s an excellent tool to get your DE into tight and hard-to-reach corners of your house with minimal effort.

If you have noticed an infestation, you should also treat the outside of your home. Here’s how to use diatomaceous earth for fleas in yard:

1Sprinkle the DE over the whole yard, especially where your cat spends its time
2Use the substance when the ground is dry and re-apply after watering or rain
3 Make sure DE reaches the ground

Diatomaceous Earth Application for Fleas: Other Uses

Apart from controlling fleas and other insects, DE also has other uses. I have, for example, used it on cat litter. This type of application is not new. People have used DE this way for many years. It is excellent for this use because of its highly absorbent properties. It works much like a Silica product. It’s also an eco-friendlier alternative to clay litters, and it can be flushed down the toilet with no trouble. You’ll actually find plenty of cat litter manufacturers using DE in their products.

DE may also be used in controlling internal parasites in livestock and home animals. It has often been hailed as a safe alternative to chemical de-wormers. And since it is not chemical, worms can’t build immunity against it. However, more studies are still being conducted to determine the efficiency levels of DE for this purpose.

Is Diatomaceous Earth Safe for Cats?

DE is a naturally occurred and non-toxic substance. That means it is safe to use on your pet. However, I recommend looking for a food grade diatomaceous earth for flea control product. Food grade substance is safe to use around the house and even in your pet’s food, which is important as the powder might get on a lot of things in your house while dusting.

Are You Using Diatomaceous Earth for Your Cat?

If you want to kill and prevent pests and the diseases they bring, you definitely need DE. It is a natural and safer alternative to most pesticides. Buying DE for your cat for preventing fleas on it will save you both time and money, as you will make fewer trips to the vet.

I want to remind you that the DE comes in different varieties. So, choose food grade diatomaceous earth for fleas if you are using it around your household. There are many options of diatomaceous earth with calcium bentonite for fleas available. From my experience and other users’ reviews, Harris and Red Lake diatomaceous earth for fleas are the most popular options.

  1. My cat has asthma and is on an inhaler twice a day. Is it safe to put DE on his body? If so, where on the cat do I apply the DE? Can I just apply a small amount on the back of his neck and at his tailbone?

    • Hello, Jean! Very sorry about your cat’s disease, hope he’s feeling okay.

      Diatomaceous earth can sometimes irritate the mouth, lungs, skin and eyes. It may cause some irritation if used near either people or pets that suffer from respiratory diseases, asthma in particular. We recommend you to consult the veterinarian first. If your doctor guarantees safety, then you can try to mix a small amount of DE with some chlorine. This way, you’ll test your cat for allergic reactions of any kind and find out if it helps with the flea problem.

      Remember that diatomaceous earth is an irritant, so it’s better to choose some more benign options, like HARRIS Diatomaceous Earth Food Grade, and dilute it with water before applying.
