Dust mites live in the homes we try so hard to keep clean. They are in the pillow, the couch and the carpet, and they have been there for as long as there has been a bed. If dust mite allergy runs in your family, you may have spent years fighting a battle that cannot be won.
Here is the good news. You do not need to win. You need to cut their numbers and the allergen they leave behind. That is a smaller, easier job, and it works.

What Dust Mites Are, and What They Are Not
Dust mites are microscopic creatures, about a third of a millimeter long. They feed on the skin flakes that people and pets shed every day. They do not bite, burrow into skin or spread disease.
The trouble is their droppings and body fragments. These contain proteins that set off allergies and asthma in some people. The particles are light and get into the air when you make a bed or vacuum, then settle again. In the United States, a large national survey found detectable dust mite allergen in about four out of five homes. Millions of people live with mites and never feel a thing. If you are allergic, even a small amount matters.
Mites need warmth and moisture. They thrive when indoor humidity runs above about 50 percent, and they struggle when it stays lower. That is why the humidity step matters so much.
Dust Mite Control Methods Compared
| Method | How well it works | Typical cost | Effort |
|---|---|---|---|
| Mite-proof mattress and pillow covers | Very good; blocks the allergen from reaching you | About $25 to $65 per bed | One time |
| Hot-water bedding wash (130°F or hotter) | Very good; kills mites and washes out allergen | Laundry cost | Weekly |
| Sealed HEPA vacuum | Good; removes allergen from floors and upholstery | About $160 to $310 | Weekly |
| Humidity control (30 to 50 percent) | Good; slows mite growth | Dehumidifier cost plus power | Low |
| HEPA air purifier | Modest; catches the allergen that gets airborne | About $90 and up | Low |
| All of the above together | Best | Varies | Medium |
Looking ahead, dust mite care is likely to get better. Allergists already offer allergy shots and a dust mite tablet that dissolves under the tongue, and researchers keep testing new versions. Warmer, wetter weather may also change how many mites live in a home. The catch is that treatments take months to work, so they sit on top of cleaning, not in place of it.
The Best Defense, Step by Step
- Zip up the bed. You spend about a third of your life there. Put a mite-proof cover on the mattress and every pillow. Regular mattress protectors do not count unless they zip around all sides and have a tight weave. See our ranking of the best dust mite mattress encasements.
- Wash bedding every week in hot water, 130°F (54°C) or hotter if the label allows. Dry on a hot setting too. For stuffed toys that cannot take heat, a day in the freezer kills the mites, but wash them afterward to remove the allergen.
- Vacuum weekly with a sealed HEPA machine. A vacuum with a leaky body and a HEPA filter on the outlet can still blow fine dust back into the room. See our ranking of the best HEPA vacuums for dust mites.
- Keep humidity at 30 to 50 percent. Use a cheap humidity meter, and a dehumidifier if you need one. Our bedroom dehumidifier guide and the dehumidifier buying guide help with the choice.
- Cut the dust catchers. Hard floors, washable rugs and fewer pillows and stuffed toys mean fewer places for mites to live. Wall-to-wall carpet in the bedroom is the hardest to keep clean.
- Add a HEPA purifier for the bedroom if allergies are bad. It will not replace the steps above, but it catches the allergen you stir up. See the best air purifiers for dust.

The risk to watch is gadget hype. Sprays, “anti-mite” gadgets and UV wands sell well and prove little, and some sprays can irritate lungs. Expect more of them each year. A zipped cover, a hot wash and a good vacuum will beat nearly all of them.
FAQ
Where do dust mites live in a home?
Mattresses, pillows, couches and carpets are the top spots. They prefer warm, humid places where skin flakes build up. Hard floors and tile hold few, so a bedroom with a hard floor and a zipped mattress is the easiest to keep under control.
Can dust mite allergy cause asthma?
Yes. Dust mite allergen is a common trigger of asthma symptoms such as coughing, wheezing and chest tightness, and it can make asthma worse at night. If breathing gets worse in the bedroom, talk to a doctor. Read our guide to asthma symptoms and management.
How many dust mites are in a bed?
Nobody can give an exact number for your bed. Studies have found large numbers in mattresses and bedding, and heavy dust can hold hundreds of mites per gram. That sounds alarming, but most people feel nothing. The number matters if you are allergic.
Will a dehumidifier get rid of dust mites?
It slows them, but it does not wipe them out. Mites need moisture, and a home kept below 50 percent humidity is a harder place to live. Combine it with covers, hot washes and vacuuming.
Do you need a special mattress cover?
Yes. A plain cover does not stop the allergen. Look for a zippered cover that closes on all six sides and says it is dust mite proof, with a fabric tight enough to block mite bodies and their droppings. Some brands carry an Asthma and Allergy Friendly certification, which is a good sign. Good covers cost about $25 to $65 and last for years.
Does a regular vacuum spread mites around?
It can. A vacuum with a poor filter or a leaky body can blow fine allergen back into the air. A sealed vacuum with a HEPA filter keeps it inside. If anyone in the house is allergic, it is worth the extra money.
Bottom Line
You cannot get rid of dust mites. You can make your home a poor place for them. Zip the bed, wash it hot, vacuum with a sealed HEPA machine and keep the air dry. Those steps handle most of the problem. If symptoms continue, see an allergist, and look at our guides on air purifiers for allergies and common household allergens.
What happens next: more homes are airtight and humid in summer, which suits mites. If that sounds like your home, keep a humidity meter in the bedroom, and keep it below 50 percent. If symptoms stay after all the steps here, an allergist can confirm that mites are the cause with a simple test.
