Dermatophagoides pteronyssinus (D. pteronyssinus), commonly referred to as the European house dust mite, is a prevalent indoor allergen. These microscopic creatures thrive in warm, humid conditions and feed on organic material such as shed human skin flakes. Their body fragments and waste products can trigger allergic reactions and asthma in susceptible 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.
