Dust mites. You can’t see them, but they’re everywhere—your bedding, your couch cushions, your rugs and, yes, your favorite recliner. These tiny, eight-legged creatures are like the worst kind of houseguest: They never pay rent, they eat your skin flakes, and they leave behind waste that makes you sneeze.

Even if you’re not particularly allergy-prone, dust mites can still mess with your health. Their droppings and body fragments (yes, really) are known triggers for asthma, eczema, and year-round sniffles that show up every morning like clockwork. If you’ve ever woken up feeling like you slept under a hay bale, dust mites might be the reason.

So how do you get rid of them? The good news: You don’t need a professional fumigator or a suitcase full of toxic spray bottles. You just need some simple, budget-friendly steps—and a little consistency.

Wash Your Bedding in Hot Water (Or Freeze It)

Start by washing your sheets, pillowcases, blankets, and mattress covers once a week in hot water—at least 130 degrees Fahrenheit. That temperature is high enough to kill dust mites on contact. If you’re not sure your water gets that hot, a high-heat dryer cycle helps, too.

For items that can’t go through the wash—think throw pillows, delicate stuffed animals, or vintage quilts—put them in a sealed plastic bag and place them in the freezer for 24 to 48 hours. The cold will kill dust mites just as effectively. Just give everything a good shake or vacuum after freezing to remove leftover allergens.

This weekly routine might feel like a lot at first, but it’s one of the easiest ways to cut down the mite population in your home—and your sinuses will thank you.

Vacuum (And Not Just the Floor)

Dust mites love soft surfaces. That means carpets, rugs, mattresses, and upholstered furniture. Vacuum at least once or twice a week using a vacuum with a high-efficiency particulate air filter, which is designed to trap even the tiniest particles instead of just stirring them up and redistributing them like glitter at a preschool birthday party.

And take your time—slow vacuuming is more effective. Quick passes just rearrange the mites instead of removing them.

Pro tip: Don’t forget to vacuum your mattress and box spring monthly. They’re like luxury condos for mites.

Dehumidify the House

Dust mites thrive in warm, humid environments. If the air in your home feels sticky, chances are the mites are thriving. Use a dehumidifier or run your air conditioner regularly to keep indoor humidity below 50 percent. You can pick up a small hygrometer at a hardware store to monitor moisture levels.

In bathrooms and kitchens, use exhaust fans while cooking or showering, and open windows on dry days to let fresh air circulate.

Even simple changes—like not drying clothes indoors—can make your home less appealing to mites.

Get Zippered Covers

Encasing your pillows and mattress in allergen-proof zippered covers cuts off dust mites from their favorite hangout spots. It also traps the ones already living there so they eventually die off. Look for covers labeled “dust mite-proof” or “allergen barrier.”

This small investment can make a big difference, especially if you or your loved ones wake up with itchy eyes or congestion.

Declutter and Downsize Dust Traps

Take a look around your bedroom. That pile of throw pillows, heavy curtains, and decorative blankets might look cozy, but to dust mites, it’s a full-service resort.

Simplify where you can: Use washable blinds instead of curtains and lightweight blankets instead of piles of fleece throws. Minimalism isn’t just trendy—it’s practical.

Bonus Tips

Steam-clean rugs and upholstery every few months for a deep, chemical-free clean.

Take your shoes off at the door—shoes track in dirt and the allergens that mites love.

Replace pillows every one to two years. They can double in weight because of accumulated dust and—you guessed it—mites.
