Getting rid of dust mites can be challenging. These nest-building, spider-like pests do not bite and are so tiny the mites can only be seen with a microscope. Dust mites thrive on discarded skin cells in moist, dark places like mattresses, carpets, upholstered furniture, and bedding. These microscopic pests are not the dust particles themselves, but indoor dust and dander can contain as many as 19,000 dust mites in one gram of dust.

What Are Dust Mites?

Dust mites are microscopic, spider-like creatures that thrive in warm, humid environments. Measuring only about 0.2–0.3 millimeters in size, they are invisible to the naked eye and can only be seen under a microscope. Unlike other household pests, dust mites do not bite, sting, or burrow into the skin. However, their presence can still cause significant health issues, particularly for those with allergies or asthma.

Dust mites are commonly found in areas where people and pets spend the most time. They thrive in soft, fibrous materials that trap moisture and provide ample food sources. Some of their favorite hiding spots include:

• Mattresses and pillows – where they feed on dead skin cells shed during sleep
• Carpets and rugs – especially in humid climates or areas with heavy foot traffic
• Upholstered furniture – such as couches, chairs, and fabric-covered surfaces
• Bedding and curtains – where dust and pet dander easily accumulate

These tiny pests survive by consuming flakes of dead skin shed by humans and animals. Their diet primarily consists of:

• Human skin cells – which naturally shed throughout the day and night
• Pet dander – microscopic flecks of skin shed by cats, dogs, and other furry animals
• Other organic debris – including mold spores and dust particles

Although dust mites do not carry diseases, their waste and shed body parts contain proteins that can trigger allergic reactions. Given that a single gram of household dust can contain thousands of dust mites, controlling their presence is essential for maintaining a healthier indoor environment.

Where Do Dust Mites Come From?

Dust mites eat particles of dead skin and dander, which is why they thrive in places where animals and people are present. Although these pests can be a nuisance, they do not live on people, spread diseases, or bite. Dust mites are only harmful when people who are allergic to them are present. How so? The enzymes found in dust mites and feces trigger allergy symptoms in people. A pest that averages about 20 droppings per day is more than harmful for a person with a dust mites allergy. 

A person exposed to dust mites can lead to various health problems. This is particularly true in children who can become asthma sufferers due to exposure to dust mites. Many allergy and asthma physicians acknowledge that dust mites may lead to many allergy symptoms, such as a runny or stuffy nose, watery/itchy eyes, and sneezing.

Are You Allergic to Dust or Dust Mites?

Indoor dust and dander are common problems for those who suffer from dust allergies or asthma. They are two of the most common allergens inside your home, including dust mites that live in your bedding and upholstered furniture. These dust mites thrive in warm, humid places and are not common in dry climates.

People often get the wrong idea that having dust problems is a sign of a dirty house. While having an unkept home may aggravate the situation, people who thoroughly clean their homes regularly may be surprised to find indoor dust and dander lingering in their homes. Standard cleaning products and procedures alone cannot easily remove substances that are present in dust. Most allergy sufferers, especially those with a dust mites allergy, will find that regardless of how clean or dirty a house is, the presence of even a small amount of indoor dust can trigger symptoms. 

However, let’s clear something up. Some people are allergic to dust, and others are allergic to dust mites. Read on to find which one you need to remove.

What Causes Dust Allergies?

“Dust bunnies” come to mind when people think of dust in their homes or property. Many people would be surprised to know that the clumps of dust that settle on their countertops and behind their furniture are more than dust and debris from the outdoors. Most of it is produced indoors inside your home or property. 

Dust is a combination of irritants, including dust mites, dust mite fecal matter, cockroach body parts, cockroach droppings, fibers, hair, shed skin cells, mold spores, pollen, bacteria, and pet dander. In metropolitan areas, dust in the home may also contain smoke and soot particles from the atmosphere. The size of dust and its potential to irritate you depends upon the source, composition, and even your geographical location.

Can Air Purifiers Get Rid of Dust Mites?

Because dust mites dwell in places with a lot of human traffic, they readily become airborne. They can become aggravated and float into the air when people vacuum, sit down on couches or bedding, and walk on carpeting. When airborne, they can be inhaled or come in contact with your eyes and skin, producing further irritation. 

Air purifiers can play a critical role in preventing allergic reactions to dust mites by trapping the airborne mites in their powerful filters. The best air purifiers for the dust are high-performance HEPA air purifiers are designed specifically to remove airborne allergens and dust from the air, including dust mites.

Air purifiers are efficient, powerful tools for dust prevention, working to remove dust mites and their droppings while they’re airborne. Ultimately, if dust mites are on your furniture, bed, or upholstery, an air purifier will have limited effectiveness at removing them.

Getting rid of dust mites is difficult because the insects are so tiny, making it hard to see the damage they cause. However, you can get off to a good start by measuring the temperature and humidity inside your home. Doing so will help you remove dust mites that are not just airborne. Dust mites enjoy warm, humid temperatures (70-80% humidity and 68 to 77°F), so it is vital to keep your indoor humidity levels below 55-percent. You can use vent fans and dehumidifiers to control your home’s humidity and kill dust mites naturally.

Other Ways to Get Rid of Dust Mites Naturally

1. Wash Bedding Frequently

Bedding is one of the primary areas where dust mites thrive, feeding on the dead skin cells that accumulate there. To effectively reduce mites in your bedding:

• Wash sheets, pillowcases, and blankets in hot water at temperatures of 130°F (54°C) or higher to kill mites and remove their waste.
• Use allergen-proof covers on pillows and mattresses. These covers act as a barrier to prevent dust mites from colonizing your bedding, making it more difficult for them to survive.

2. Vacuum and Dust Properly

Regular cleaning is essential, but you must do it properly to ensure you’re effectively removing dust mites and their allergens. To optimize your cleaning efforts:

• Use a vacuum with a HEPA filter, which is designed to trap small particles, including dust mites and their fecal matter. HEPA vacuums prevent mites from being released back into the air as you clean.
• Dust with a damp cloth instead of a dry one. Dry dusting can cause particles to become airborne, making it easier for dust mites to spread throughout your home. Damp cloths capture dust, preventing it from re-entering the air.

3. Minimize Soft Surfaces

Dust mites love to inhabit soft, porous surfaces that trap moisture and organic debris. To reduce the ideal habitat for dust mites:

• Limit carpeting in bedrooms, living rooms, and other frequently used spaces. Consider replacing carpets with hardwood floors, tile, or vinyl, which are easier to clean and don’t trap dust.
• Opt for washable area rugs instead of heavy drapes or upholstery that can hold dust. Regularly wash and vacuum these alternatives to keep them free from dust mites.

4. Freeze Items to Kill Mites

Some household items cannot be washed but can still harbor dust mites. To deal with these items:

• Place non-washable fabrics, like stuffed animals, decorative pillows, or soft toys, in a plastic bag and freeze them for 24-48 hours. The cold will kill dust mites and their eggs, making it safe to return these items to your home without worrying about mites.

By following these natural methods, you can significantly reduce dust mite populations in your home, improving indoor air quality and helping to alleviate allergy symptoms.

Conclusion

Dust mites are a common and often overlooked allergen in many homes. While these microscopic pests do not bite or spread diseases, their waste and body parts can trigger significant allergic reactions, particularly in those with asthma or sensitivities to dust. Understanding where dust mites thrive—such as in bedding, carpets, and upholstered furniture—and knowing what they feed on can help you target the areas where they are most likely to accumulate.

By implementing natural strategies like reducing humidity, washing bedding frequently, and properly vacuuming and dusting, you can effectively reduce dust mite populations in your home. Taking steps to minimize soft surfaces and freezing non-washable items can further prevent dust mites from settling in. With regular maintenance and attention to indoor air quality, you can create a healthier living environment, reduce allergy symptoms, and improve overall comfort in your home.
