Dust mites
Dermatophagoides spp.
Description
Dust mites (Dermatophagoides spp.) are microscopic organisms, around 0.2–0.3 mm long and invisible to the naked eye. They live in mattresses, pillows, carpets, sofas and fabrics, where they feed on the skin flakes we shed every day.
They thrive in warmth and humidity. They do not bite or directly transmit diseases, but their remains and droppings are among the main allergens in homes.

Risks and spread
The main risk from dust mites is allergic: their allergens can trigger and aggravate respiratory and skin conditions.
- Respiratory allergies — Among the most common causes of allergic rhinitis indoors.
- Asthma — The allergens can trigger or worsen asthma in sensitive individuals.
- Dermatitis — Can contribute to skin reactions such as atopic dermatitis.
- Air quality — Reduce the healthiness of frequently used spaces.
