Human Itch Mite

Natural Habitat

The mite lives exclusively on and within human skin, specifically burrowing into the upper layer (stratum corneum).

Diet & Feeding

They feed on human skin cells and extracellular fluid found within the burrows they create.

Behavior Patterns

Pregnant females burrow into the skin to lay eggs, creating visible zigzag tracks. They are most active at night, which often leads to increased itching for the host. The life cycle from egg to adult takes about 10-14 days.

Risks & Benefits

Risks: Causes scabies, characterized by intense itching and a pimple-like rash. It is highly contagious through direct skin-to-skin contact. If untreated, secondary bacterial infections can occur from scratching. Benefits: None; they are strictly parasitic to humans.
