We describe two different studies of storage mite allergy from the Stavanger area performed among 2,273 patients who were referred to ear, nose and throat specialists. Storage mite allergy is common in the western part of Norway. It is a major factor in the development of allergic rhinoconjunctivitis and asthma in rural areas and among allergic patients living in damp houses. We conclude that, in western Norway, storage mites should be included in standard skin test when allergic rhinoconjunctivitis and/or asthma is suspected.
