Dermatophagoides farinae, or the American house dust mite, is a major allergen in household dust. These mites are ubiquitous in upholstered furniture, carpets, and bedding, where they feed on skin cells shed by humans. Their fecal matter and body fragments can cause allergic reactions year-round, often leading 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.
