Dermatophagoides farinae (D. farinae), also known as the American house dust mite, is a common allergen found in household dust. These mites are widespread in carpets, bedding, and upholstered furniture, where they feed on human skin cells. Their fecal matter and body fragments can trigger allergic reactions throughout the year, often contributing to allergic rhinitis and asthma.
Consider testing for a D. farinae allergy if you frequently suffer from indoor allergy symptoms such as sneezing, nasal congestion, or itchy eyes, especially in bedrooms and other areas with fabric surfaces.
The proteins found in D. farinae mites’ droppings and decaying bodies can provoke an allergic reaction when inhaled or when they come into contact with the skin.
Reduce home humidity levels, encase mattresses and pillows in allergen-proof covers, frequently wash bedding in hot water, and vacuum regularly using a vacuum with a HEPA filter.
