Itch mite
Sarcoptes scabiei
- Order & Family
- Order: Sarcoptiformes, Family: Sarcoptidae
- Size
- Microscopic; adult females are approximately 0.30–0.45 mm long, while males are about half that size.
Natural Habitat
Human skin, specifically within the stratum corneum (top layer) where females burrow to lay eggs.
Diet & Feeding
They feed on skin cells and extracellular fluid found within the burrows they create in the host's skin.
Behavior Patterns
Mites are transmitted through direct, prolonged skin-to-skin contact. Females burrow into the skin to lay eggs, which hatch into larvae that move to the surface to mature and repeat the cycle.
Risks & Benefits
Risks include scabies, a highly contagious skin infestation characterized by intense itching and a pimple-like rash. Secondary bacterial infections can occur from scratching.
