Are dust mites microorganisms

Dust mites are not microorganisms; they are small arthropods belonging to the subclass Acari, which also includes ticks. While they are microscopic in size, typically measuring around 0.2 to 0.3 millimeters in length, they are classified as multicellular organisms rather than single-celled microorganisms like bacteria or viruses. Dust mites thrive in warm, humid environments and feed on organic matter, particularly dead skin cells.
