Diatomaceous earth is a naturally-occurring sedimentary rock that is made up of the fossilized remains of tiny aquatic creatures called diatoms. The sharp edges of these fossils can cut through the exoskeletons of insects, causing them to dehydrate and die. This makes it an effective and safe way to control pests like fleas, ticks, and mites in your home.

You can apply diatomaceous earth to your cat by using a powder duster or puffer bottle. Simply dust or puff the powder onto your cat’s fur, being careful to avoid their eyes, nose, and mouth. Work the powder into their fur with your fingers until it is evenly distributed, then brush it out with a soft bristle brush.

Repeat this process every few days until you see a decrease in pests.

  • Purchase food grade diatomaceous earth and spread it around your home where your cat typically spends time
  • Avoid using products with chemicals or fragrances as these can be harmful to your cat’s health
  • As you apply the diatomaceous earth, be sure to keep your cat away from the area until it is completely dry
  • Vacuum regularly to remove any residual powder and monitor your cat for any adverse reactions such as itchiness, redness, or excessive scratching

How Do You Apply Diatomaceous Earth to Pets?

Diatomaceous earth is a naturally-formed sedimentary mineral rock. It’s derived from the remains of diatoms, or oceanic unicellular algae. Diatoms are over 30 million years old and are formed from the cementation of microscopic algae-like plant remains into the earth’s surface.

DE is 87% silica, with the remaining13% made up of other minerals, including calcium, sodium, iron and magnesium. These minerals give DE it’s characteristic off-white color. When ground into a fine powder, DE is odorless, non-toxic and has a slightly abrasive texture.

This natural product can be used in many different ways, but one common use is as a pet dewormer. How to Use DE as a Pet Dewormer? The first step is to make sure you purchase food grade DE—this type hasn’t been exposed to chemicals during processing and is safe for consumption.

Once you have your DE, mix 1 teaspoon per 10 pounds of your pet’s body weight into their food once per day for three days in a row. After three days have passed, reduce the dosage to 1 teaspoon per 20 pounds of body weight given every other week until symptoms disappear.
