House dust mite allergy factsheet
Introduction
House dust mites are tiny insects that live indoors and feed off dust, pollen, and human skin cells. They are very small and cannot be seen on clothing or objects.
House dust mites will do around 20 poos or droppings daily to get rid of waste. These droppings contain proteins that can cause allergic reactions in some people.
House dust mites live in humid areas and are found on soft furnishings like:
- bedding
- carpets
- clothing
- curtains
- soft toys.
House dust mite allergies are very common and can also be linked to conditions like:
Signs and symptoms

Diagnosis
A specialist doctor can diagnose a house dust mite allergy based on your child’s:
- medical history
- signs and symptoms
