Dermatophagoides pteronyssinus (D. pteronyssinus), commonly known as the European house dust mite, is a common indoor allergen. These microscopic organisms thrive in warm, humid environments and feed on organic matter such as shed human skin flakes. Their body fragments and waste products can provoke allergic reactions and asthma in sensitive individuals.
If you experience year-round allergy symptoms, particularly after dusting your home or in bed, testing for a D. pteronyssinus allergy can be beneficial.
Allergic reactions to D. pteronyssinus are triggered by proteins in the mite’s waste and decaying body parts, which can be inhaled or come into contact with the skin.
To manage this allergy, lower indoor humidity, wash bedding in hot water weekly, use allergen-proof bed covers, and vacuum regularly with a HEPA filter.
