What Is Diatomaceous Earth?

Diatomaceous earth or DE is a powdery compound derived from the fossilized remains of miniature aquatic algae known as the diatom. The remains of the miniature sea life often transcend 100,000 years and are easily broken to fine white powders.

While the term diatomaceous earth can be rather alien, you may have used or come across with diatomaceous earth in daily life. The high concentration of silica in diatomaceous earth makes it a sought-after component for both industrial and commercial purposes.

Some common applications of diatomaceous earth include water filtration, food production, skin products and a good agent in pest control, including dust mites.

Does Diatomaceous Earth Kill Dust Mites?

Diatomaceous earth is a lethal agent for pests shaped with an exoskeleton, such as dust mites. The tiny powder has sharp edges that tear into the protective layer of dust mites exterior. It then dries out the organism upon contact and once the dust mites are void of fluid, they are exterminated.

The effectiveness of diatomaceous earth for pest control has been proven in a study conducted by the University of British Columbia. Laying hens that are dusted with diatomaceous earth has shown a significant reduction in Northern fowl mite infestations.

As a natural agent, diatomaceous earth may take a few days before it eliminates the dust mites infesting your home. You’ll also want to take note that diatomaceous earth will not work on the eggs of dust mites, which means you’ll need a continuous effort in keeping dust mites under control.

Is Diatomaceous Earth Safe?

When using diatomaceous earth, it’s important to find out if it’s safe for humans and pets. That’s because there are two types of diatomaceous earth that are available, i.e.,  the crystalline vs non-crystalline.

Crystalline diatomaceous earth is widely used in industrial applications. This filter-grade diatomaceous earth powder contains a high amount of crystalline (>60%) and is found to be harmful to health. When inhaled on a consistent basis, it can increase the risk of lung cancer as found in this study.

If you’re using diatomaceous earth to killing dust mites in your home, you’ll want to choose food-grade or non-crystalline diatomaceous earth. It contains less than 2% of crystalline and is approved by the FDA for usage in food and agricultural applications.

With that said, you should take precautions when using food-grade diatomaceous earth. It has been suggested that inhaling diatomaceous earth can be linked to lung irritation and potential scarring of the lungs.

How To Use Diatomaceous Earth For Dust Mites

  4. Leave the diatomaceous earth for a few hours before removing the powder with a vacuum cleaner.
  5. You’ll want to repeat the process for a few weeks to reduce the growth of dust mites at home.

Of course, diatomaceous earth shouldn’t be the only solution that you applied to reduce dust mites. It works well when incorporated in part of your cleaning routine at home.
