Natural Habitat

The epidermis (outer layer) of human skin, particularly in folds, webbing between fingers, and wrists.

Diet & Feeding

The mites feed on skin cells and extracellular fluid (serum) by burrowing into the skin.

Behavior Patterns

Pregnant females burrow into the upper layer of the skin to lay eggs. They move mostly at night and can live for 1-2 months on a human host. Outside the host, they can only survive for 2-3 days.

Risks & Benefits

Causes Scabies, a highly contagious skin infestation characterized by intense itching and a pimple-like rash. It is a significant public health risk as it spreads through direct skin-to-skin contact. There are no ecological benefits to humans.
