Answer

In the United States, 2 major house dust mite species are associated with allergic rhinitis. These are Dermatophagoides farinae and Dermatophagoides pteronyssinus. [42]

These mites feed on organic material in households, particularly the skin that is shed from humans and pets. They can be found in carpets, upholstered furniture, pillows, mattresses, comforters, and stuffed toys.

While they thrive in warmer temperatures and high humidity, they can be found year-round in many households. On the other hand, dust mites are rare in arid climates.
