What common allergen do house dust mites feed on?

House dust mites primarily feed on skin and dander. Humans naturally shed skin cells, which contain proteins that serve as a food source for these tiny, microscopic organisms. This feeding behavior is significant because it highlights the connection between household cleanliness and allergic reactions. When dust mites consume skin cells, they produce waste products that can become airborne and trigger allergic responses in sensitive individuals.

While other options like plant pollen, animal fur, and food debris might contribute to allergies, they do not specifically serve as the primary food source for house dust mites. Understanding that skin and dander are the main components that support the thriving populations of house dust mites is crucial for addressing indoor allergen management and improving indoor air quality.
