Overview
Dust mites are tiny organisms that live in bedding, carpets, upholstered
furniture, and other soft furnishings. You can’t see them without a
microscope.
While dust mites don’t bite, they’re one of the most common indoor allergy
triggers in Australia. Their waste and body fragments can cause allergy
symptoms in sensitive people. Dust mites are a common cause of perennial, or
year-round, allergic rhinitis and can also worsen asthma and eczema symptoms
in some people.
A dust mite allergy can cause symptoms year-round. This can affect your sleep, work, school, and
daily life. This article explains the symptoms, causes, ways to reduce dust
mite exposure, management options, and when to see a doctor.
What is a dust mite allergy?
A dust mite allergy occurs when your immune system reacts to proteins found
in dust mite droppings and body fragments. Dust mites don’t bite or sting.
Unlike bed bugs, which are visible and feed on blood, dust mites are
microscopic and trigger symptoms through the allergens present in household
dust. As they live indoors year-round, symptoms are often persistent.
Where are dust mites commonly found?
Dust mites are commonly found in:
- Mattresses
- Pillows
- Bedding
- Blankets
- Carpets and rugs
- Upholstered furniture
- Curtains
- Soft toys
- Fabric-covered furniture
Dust mites thrive in warm, humid environments, which is why they’re commonly
found in bedding and soft furnishings.

How do you know if dust mites are causing your allergies?
Unlike seasonal pollen allergies, dust mite allergies often cause year-round
symptoms. The table below highlights the key differences, but allergy testing
is the best way to identify the cause.
| Clue | More likely dust mites | More likely another trigger |
|---|---|---|
| When symptoms happen | All year round, with little change between seasons | Only at certain times of the year (pollen) or around certain animals |
| Where symptoms are worse | Worse in beds, in the morning, or in dusty rooms | Worse outdoors, or straight after being near an animal |
| Home environment | Symptoms are worse in humid or poorly ventilated rooms | No clear link to humidity |
| Confirming the cause | Allergy testing (skin prick or blood test) can confirm a dust mite allergy | Allergy testing can also identify other triggers |
How to stop or reduce dust mite allergies
You can’t completely get rid of dust mites. However, reducing your exposure
can improve your symptoms.
1. Wash bedding weekly
- Wash sheets and pillowcases in hot water, above 60°C, where appropriate.
- Dry thoroughly before use.
2. Use dust mite-proof covers
- Mattress protectors
- Pillow protectors
- Doona or quilt covers
3. Vacuum regularly
- Use a HEPA-filter vacuum cleaner where possible
- Vacuum carpets and upholstered furniture
4. Reduce indoor humidity
- Improve ventilation
- Use a dehumidifier if needed
- Keep humidity low where practical
5. Remove dust-trapping items
- Heavy curtains
- Excess cushions
- Soft toys
- Thick rugs
6. Clean bedrooms frequently
- Dust surfaces regularly
- Wash blankets
- Clean under the bed
Natural ways to help reduce symptoms
These natural approaches may help relieve symptoms, but they don’t eliminate
dust mites.

- Improving indoor ventilation
- Maintaining good indoor air quality
This information is for educational purposes only. You should consult a
doctor or medical practitioner before attempting home remedies or new
wellness programs to ensure they are safe for your specific condition.
When should you see a doctor?
See a doctor if:
- Symptoms persist despite home measures
- Your sleep is affected
- Symptoms disrupt your daily activities
- Your asthma symptoms worsen
- You get frequent sinus infections
- Symptoms continue throughout the year
Medical emergencies: When immediate care is needed
If you experience severe, worsening, or life-threatening symptoms, call
000 immediately or attend your nearest Emergency Department (ED). Examples
include:
- Difficulty breathing or gasping for air
- Swelling of the throat, tongue, or face
- Severe allergic reactions (anaphylaxis)
- Loss of consciousness or collapse
- Wheezing that does not improve
Can telehealth help with dust mite allergies?
Telehealth is a convenient option for appropriate healthcare needs and can
complement in-person healthcare. However, telehealth may not be suitable for
every condition. Because dust mite allergies can involve skin conditions or
respiratory symptoms, some patients may require an in-person assessment,
physical examination, testing, or emergency care.
- Assessing allergy symptoms
- Discussing likely triggers
- Treatment advice
- Online prescriptions, where clinically appropriate
- Allergy management plans
- Referrals for allergy testing or specialist care
Your doctor may recommend an in-person examination or allergy testing if they
need a closer look or if your symptoms suggest an alternative diagnosis.
