Dermatophagoides farinae is a common species of dust mite found in homes, particularly in bedding, carpets, and upholstered furniture. These tiny, microscopic creatures thrive in warm, humid environments and feed primarily on dead skin cells shed by humans and pets. While they are not harmful to most people, Dermatophagoides farinae can trigger allergic reactions in sensitive individuals. Symptoms may include sneezing, runny nose, and itchy eyes. Regular cleaning and reducing humidity can help minimize their presence in living spaces.
