Dust mites are microscopic creatures that feed off human skin scales. They are one of the most common allergen triggers for asthma, especially in humid and coastal parts of Australia.

They live in soft furnishings such as beds, bedding, carpets, upholstered furniture, soft toys and clothing, and are mostly found in people’s homes rather than public places.

Dust mites are not usually in the air and only become airborne during and after dust-raising activities such as vacuuming and dusting.
