Dust mites are tiny, naked eye, creatures that thrive in the warm, humid environments of our homes, especially in bedding, carpets, and upholstery. While they’re not harmful in and of themselves, dust mites produce waste and shed skin that can trigger allergies and asthma. If you’re looking for a natural and effective solution to get rid of dust mites, diatomaceous earth (DE) might be the answer. Let’s explore how diatomaceous earth works against dust mites, why it’s a safe alternative to chemical pesticides, and how to use it effectively in your home to reduce the dust mite population.
What is Diatomaceous Earth?
Diatomaceous earth is a naturally occurring, soft sedimentary rock made from the fossilized remains of diatoms, a type of microscopic algae. When crushed into a fine powder, DE has a unique abrasive texture and contains silica, which makes it effective in breaking down the exoskeletons of insects and other pests. While harmless to humans and pets when used properly, DE is the perfect pest control method for pesky insects, including dust mites.
How Does Diatomaceous Earth Work on Dust Mites?
Dust mites thrive in warm, humid environments and feed primarily on dead human skin cells, which accumulate in areas like mattresses, pillows, and carpets. Diatomaceous earth works by absorbing moisture from the dust mites' environment and dehydrates them upon contact. The microscopic sharp edges of DE can also puncture the protective outer layer (exoskeleton) of the mites, causing them to dehydrate and die.
The benefit of using diatomaceous earth over other treatments is that it doesn’t just kill the mites—it creates an environment where they can’t thrive. Dust mites need moisture to live, so by applying DE in places where they congregate, you can help to eliminate both the mites and the conditions that help them multiply.
Why Choose Diatomaceous Earth for Dust Mites?
Chemical-Free: Unlike chemical insecticides, DE is non-toxic and chemical-free, making it a safe alternative for homes, especially those with young children, pets, or individuals sensitive to harsh chemicals.
Environmentally Friendly: As a natural product, diatomaceous earth is eco-friendly. It doesn’t pollute water, harm beneficial insects (like bees), or release harmful chemicals into the environment.
Safe for Humans and Pets: When used correctly, food-grade DE is safe to use around humans and animals. It is important to note that you should use "food-grade" diatomaceous earth, which is safe for household use, rather than "pool-grade" DE, which has been chemically treated and is harmful if inhaled.
Long-Lasting Effects: DE doesn’t lose its effectiveness over time unless it gets wet. This means that once you apply it, the treatment can continue to work for weeks or months, as long as it remains dry.
How To Use Diatomaceous Earth For Dust Mites
To effectively use diatomaceous earth for dust mites, follow these steps:
Preparation
Start by thoroughly cleaning the areas where dust mites are likely to reside. Wash bedding, pillows, and blankets in hot water to kill any existing mites. Vacuum your mattress, carpets, and upholstered furniture to remove dead skin cells and other organic matter that mites feed on.
Application
Mattresses: After vacuuming, sprinkle a fine layer of diatomaceous earth over your mattress. Let it sit for several hours (or overnight) to allow the DE to absorb moisture and kill any dust mites. Afterward, vacuum it up thoroughly. Be sure to steam clean.
Carpets and Rugs: For areas with heavy mite infestations, sprinkle diatomaceous earth on carpets and rugs. Let it sit for at least 24 hours, giving the DE time to work. Afterward, vacuum the treated areas well. Be sure to steam clean.
Upholstery: Dust mites also live in couches and chairs. Lightly apply DE on upholstered furniture, and let it sit for several hours. Be sure to vacuum carefully to remove all the powder. Be sure to steam clean
Cracks and Crevices: Dust mites love hidden areas, so don’t forget to apply diatomaceous earth in cracks and crevices where they might be hiding.
Reapply As Needed
Since diatomaceous earth is only effective when dry, you’ll need to reapply it after vacuuming or cleaning. You should also reapply it periodically in humid environments or high-traffic areas to ensure long-term protection against dust mites. Always ensure those areas are steam cleaned as this helps to kill any eggs or mites themselves.
Safety Tips When Using Diatomaceous Earth
While diatomaceous earth is generally safe, it’s important to follow some basic safety precautions:
Wear a Mask: When applying DE, especially in large amounts, wear a dust mask to avoid inhaling the fine particles. Although food-grade DE is non-toxic, inhaling any dust can irritate the respiratory system.
Use Crawling Insect Control Diatomaceous Earth: Always opt for crawling insect control diatomaceous earth when using it in your home. Pool-grade DE has been chemically treated and is not safe for household use.
Keep It Dry: Diatomaceous earth loses its effectiveness when wet, so be sure to keep treated areas dry. If DE does get wet, simply reapply it once the area is dry again.
Diatomaceous Earth and Dust Mite Allergens
If you or someone in your household suffers from dust mite allergic reactions, using diatomaceous earth can help alleviate symptoms. By reducing the number of dust mites in your home, you’ll lower the risk of being allergic to dust mite feces and body fragments, in the air. This can lead to fewer dust mite allergies like sneezing, itchy eyes, runny nose, and asthma flare-ups.
For best results, use diatomaceous earth in combination with other dust mite prevention strategies, such as using allergen-proof mattress and pillow covers, regularly washing bedding in hot water, using a high efficiency particulate air filter, using a vacuum cleaner with a hepa filter, and maintaining low humidity levels in your home. Always a great idea to use a steam cleaner when cleaning carpets and furniture and it never hurts to apply tea tree oil around certain places to help repel them. You may also use essential oils around problem areas, such as eucalyptus oil.
Conclusion
Diatomaceous earth offers a natural, safe, and effective solution for controlling dust mites in your home. With its moisture-absorbing and abrasive properties, DE not only kills dust mites but also helps prevent them from coming back by creating a dry, inhospitable environment. By incorporating diatomaceous earth into your dust mite management routine, you can improve the air quality in your home and enjoy a cleaner, healthier living space.
If you’re tired of battling dust mites with chemicals or looking for a greener alternative, give diatomaceous earth a try. Your allergies—and your home—will thank you!
