Natural Habitat

Extremely host-specific parasites that live within the epidermal layer of human skin. They prefer areas like the webs between fingers, wrists, and elbows.

Diet & Feeding

Feed on human skin cells and extracellular fluid by burrowing into the stratum corneum.

Behavior Patterns

Females burrow into the skin to lay eggs. The life cycle from egg to adult takes about 10-15 days. They are most active at night, which is when itching typically worsens.

Risks & Benefits

Cause Scabies, a contagious skin infestation characterized by intense itching and a pimple-like rash. If left untreated, scratching can lead to secondary bacterial infections like impetigo. They provide no known ecosystem benefits.
