Dust Mite

Natural Habitat

Human dwellings, primarily in bedding, carpets, upholstered furniture, and mattresses, where they feed on shed human skin scales.

Diet & Feeding

Mostly dead human and animal skin cells (dander), but also fungal spores and other organic detritus. They do not bite or burrow into skin.

Behavior Patterns

Dust mites thrive in warm, humid environments. They are microscopic and not visible to the naked eye. They reproduce quickly, with a life cycle from egg to adult taking about 3-4 weeks. They are largely sedentary, preferring to stay in areas with abundant food sources and stable environmental conditions.

Risks & Benefits

Potential risks include triggering allergic reactions in sensitive individuals, such as asthma, eczema, and allergic rhinitis, due to their fecal matter and body fragments. They are not known to transmit diseases. There are no direct benefits to humans, but as detritivores, they play a minor role in breaking down organic matter in indoor environments.
