home > House dust mite allergy > Where do they hide ?


House dust mites live in our houses, public transport systems, work places and leisure facilities.
They find the best possible conditions for growing and multiplying in these places.


They are real “invaders”, invisible to the naked eye and hidden everywhere.



House dust mites grow and spread in cosy, warm nests

Dust mites in home

As house dust mites feed mainly on dead skin, they are consequently found wherever humans live. Invisible colonies of several million house dust mites proliferate in carpets and rugs, mattresses and other upholstered furniture, where they can feed on dead skin.
The house dust mites’ preferred nesting place is:

  • in the bedroom,
  • in the bedding,
  • especially in mattresses and pillows,
  • but also in duvets and quilts,
  • they also like armchairs, cushions and sofas.


Watch out for unexpected signs of house dust mites :

  • soft toys,
  • curtains,
  • carpets,
  • upholstered furniture,
  • cushions,
  • pet cages and baskets.

House dust mites thrive particularly well in humid environments (60 to 80%) and at a fairly high and stable temperature (26-32°C).


Present all year round… but especially in certain seasons

Although present in our homes and surroundings all year round, house dust mites are more numerous in autumn and winter, when the weather is wetter and we air our living spaces less. The use of heating and reduced ventilation creates ideal conditions for this creature to grow. Their concentration increases, causing allergic symptoms to peak.

Symptoms are not always identifiable

Dust mites are the primary cause of respiratory allergy1 .


Dust mite allergy symptoms:

– repeated sneezing,
– a runny nose or blocked nose,
– itchy eyes or sore throat,
– general tiredness.
These symptoms may be confused with cold or flu symptoms.


There is a strong link between dust mite allergy and asthma

Up to 85% of asthmatic patients are allergic to dust mites2. That is why it is essential to consult an allergy specialist to determine which allergens are responsible for the symptoms in order to receive appropriate treatment.
