Scientific Name: Dermatophagoides spp.

Order & Family: Order: Sarcoptiformes, Family: Pyroglyphidae

Size: Typically 0.2-0.3 mm (too small to be seen with the naked eye)

Dust Mite

Natural Habitat

Thrive in warm, humid environments, especially in mattresses, bedding, upholstered furniture, carpets, and curtains, feeding on dead skin cells.

Diet & Feeding

Primarily feed on organic detritus, particularly flakes of shed human and animal skin (dander).

Behavior Patterns

Dust mites are not parasitic; they do not bite or burrow into skin. They prefer dark, undisturbed areas and reproduce quickly in favorable conditions. Their life cycle from egg to adult is about 3-4 weeks. They produce fecal pellets and shed exoskeletons.

Risks & Benefits

Potential risks include being a major cause of allergies and asthma, as their fecal pellets and body fragments contain powerful allergens. There are no known direct benefits to humans or the ecosystem, though they contribute to the natural decomposition of organic matter.
