What Are Mould Mites and Why Should You Care?
If you’ve spotted tiny white or tan insects crawling around mouldy areas in your home, you’re likely dealing with mould mites. These microscopic creatures thrive in damp, mould-infested environments and can worsen indoor air quality, trigger allergies, and indicate underlying moisture problems.
If you’re a tenant suffering from recurring damp, mould, and now mould mite infestations, you may have the right to make a housing disrepair claim if your landlord has failed to address the root issues.
In this guide, you’ll learn how to get rid of mould mites, how to prevent them from returning, and what steps to take if poor housing conditions are to blame.
What Are Mould Mites?
Mould mites (also known as damp mites) are tiny, light-coloured insects that feed on mould and fungi. They are almost invisible to the naked eye but may appear as small moving white dots on walls, furniture, or fabrics.
Key facts about mould mites:
-
They measure around 0.2–0.5 mm in length
-
They don’t bite humans, but their shed skins and hairs can cause allergic reactions
-
They are often found near mouldy walls, ceilings, carpets, wooden furniture, or books
-
They reproduce quickly in moist, humid environments
If you see mould mites, you have a moisture problem that needs urgent attention.
Signs of a Mould Mite Infestation
-
Fine dust or powdery residue on surfaces
-
Tiny white or tan insects near mould patches
-
Increased allergy symptoms (sneezing, itchy eyes, coughing)
-
Visible black mould or damp patches on walls and ceilings
-
Musty, unpleasant odours
If you notice these signs, it’s critical to act fast.

How to Get Rid of Mould Mites – Step-by-Step
Step 1: Eliminate the Source of Moisture
Mould mites exist because mould exists.
Before treating mites, you must fix the cause of the mould:
-
Repair any leaks (roof, pipes, windows)
-
Improve ventilation in kitchens, bathrooms, and basements
-
Use a dehumidifier to keep humidity below 50%
-
Remove any standing water or damp materials
Without eliminating the moisture, mould mites will return even after treatment.
Step 2: Remove All Visible Mould
Because mould mites feed on mould, cleaning mould is essential:
-
Use white vinegar, hydrogen peroxide, or specialist mould sprays to kill surface mould
-
Scrub hard surfaces thoroughly
-
Replace heavily mould-damaged furniture or carpets if necessary
Important: Always wear gloves, goggles, and a mask when cleaning mould to protect yourself from spores and allergens.

Step 3: Deep Clean the Infested Area
Once the mould is treated:
-
Vacuum carpets, upholstery, and floors using a HEPA-filter vacuum
-
Wipe down walls, ceilings, and skirting boards
-
Steam-clean carpets and curtains if possible
-
Launder mould-exposed fabrics on a hot cycle
Disposing of badly infested materials may be necessary in severe cases.
Step 4: Treat the Mould Mite Infestation
If mites remain after cleaning, consider:
-
Natural sprays: Mix water with a few drops of tea tree oil, lavender oil, or clove oil to repel mites naturally
-
Insecticide sprays: Only use as a last resort, and choose one labelled safe for indoor use against mites
-
Diatomaceous Earth: A natural powder that can kill mites by drying them out (safe for homes if used properly)
Always focus on removing moisture first—chemical sprays alone won’t solve the root problem.
Step 5: Maintain a Dry and Clean Environment
Prevention is key to long-term mould mite control:
-
Use dehumidifiers or install extractor fans
-
Regularly ventilate your home (open windows daily)
-
Fix leaks immediately
-
Clean mould-prone areas with anti-fungal products monthly
-
Monitor humidity levels using a hygrometer
Without moisture, mould mites cannot survive.
Are Mould Mites Dangerous?
While mould mites don’t bite, they are dangerous to your indoor air quality. Their shed skin, body parts, and droppings can become airborne and cause:
-
Asthma flare-ups
-
Respiratory issues
-
Skin irritation
-
Worsened allergies
Children, the elderly, and people with weakened immune systems are particularly vulnerable.
What If Mould and Mould Mites Keep Coming Back?
If you keep battling mould and mites despite your best efforts, the underlying problem may be serious, such as:
-
Rising damp
-
Structural leaks
-
Poor insulation or ventilation
-
Hidden water damage
If you rent your home, your landlord has a legal obligation to fix these issues.
If they don’t, you could be entitled to make a housing disrepair claim for repairs and compensation.
Explore your options if damp and mould are affecting your health and quality of life.
When Can You Make a Housing Disrepair Claim?
You may qualify if:
-
Mould mites or damp have damaged your health
-
Your landlord failed to act after being informed about leaks or damp
-
Your belongings (clothes, furniture) were ruined due to mould
-
Your living conditions have become unsafe or uninhabitable

Final Thoughts: Don’t Let Mould Mites Take Over
Getting rid of mould mites isn’t just about killing the bugs—it’s about fixing the moisture and mould problem that caused them.
If your landlord is ignoring your complaints about damp, mould, and infestations, you don’t have to live in unsafe conditions. The law is on your side.
