Dust Mites and Eczema!
What You Need to Know (And How to Fight Back)
For anyone living with eczema, identifying and avoiding triggers is a vital part of daily life. One of the most common (and invisible) culprits? Dust mites. These microscopic pests can wreak havoc on sensitive skin, especially for people prone to eczema.
In this post, we’ll break down exactly what dust mites are, how they affect eczema, and—most importantly how to reduce exposure and manage flare-ups.
What Are Dust Mites?​
​
Dust mites are tiny, spider-like creatures that thrive in warm, humid environments. They feed on dead skin cells and love to hide in:
​
​
-
Bedding and pillows
-
Carpets and rugs
-
Upholstered furniture
-
Curtains
-
Soft toys
​
​
Although they’re harmless to most people, dust mites can be a serious issue for those with allergies or skin conditions like eczema.
How Do Dust Mites Affect Eczema?
​Dust mites don’t bite or sting—but their droppings, body parts, and saliva are powerful allergens. When these microscopic particles come into contact with your skin or are inhaled, they can trigger your immune system and:...
​
​
-
Irritate the skin barrier
-
Cause itchy, inflamed eczema flare-ups
-
Increase sensitivity in already reactive skin
-
Trigger asthma or allergic rhinitis, which often co-exist with eczema (known as the atopic triad)
​
​
Studies show that people with atopic dermatitis often have heightened immune responses to dust mites. In fact, over 80% of eczema sufferers test positive for dust mite allergy.
Where Dust Mites Hide (And How to Reduce Them)
You can’t see them, but you can take steps to limit their presence in your home—especially in the bedroom, where we spend a third of our lives.
​
1. Use Dust-Mite-Proof Bedding
Invest in allergen-proof covers for mattresses, pillows, and duvets. These encasements block mites from burrowing in and help reduce exposure.
​
2. Wash Bedding
Wash all bedding at 60°C or higher to kill dust mites. Lower temperatures won’t do the trick.
Keep rooms free of excess fabrics, cushions, or stuffed toys. The fewer hiding spots, the better.
​
4. Vacuum with a HEPA Filter
Use a vacuum cleaner with a HEPA filter to trap tiny particles like dust mite waste.
​
5. Control Humidity
Dust mites thrive in humidity above 50%. Use a dehumidifier or ensure good ventilation to keep moisture levels in check.
How to Treat Eczema Triggered by Dust Mites
While reducing dust mite exposure is essential, it’s also important to soothe and treat the skin.
​
1. Moisturise Religiously
Use fragrance-free, eczema-friendly moisturisers to lock in hydration and protect the skin barrier.
​
2. Topical Steroids (or Alternatives)
During a flare-up, you may need a short course of prescribed topical steroids or non-steroid alternatives to calm inflammation.
​
3. Antihistamines
If itching is intense or sleep-disruptive, antihistamines can offer relief—especially at night.
​
4. Bathing Routines
Opt for lukewarm baths, ideally with added colloidal oatmeal or emollient bath oils to soothe irritated skin. Avoid harsh soaps.
​
5. Allergy Testing & Immunotherapy
If dust mite allergy is severe, your GP or dermatologist may refer you for allergy testing or discuss options like immunotherapy (a long-term treatment to desensitise the immune system).
Final Thoughts
Managing eczema means tackling both the symptoms and the triggers. Dust mites are a common, hidden cause of flare-ups, but with the right steps — like using protective bedding, washing regularly, and reducing allergens — you can create a healthier, more eczema-friendly home.
