House dust mites and storage mites have a high allergenic potential and lead to sensitization through the formation of specific IgE antibodies. Due to their preferred stay in houses, they belong to the group of house mites, which are referred to as "domestic mites" in the English-speaking world.Their anatomy and biology justify their astonishing adaptability to changing environmental situations (e.g. temperature, humidity, food) and make it understandable that measures to reduce their frequency are usually difficult to implement in practice.
