Itch mite (Scabies mite)
Sarcoptes scabiei
- Order & Family
- Order: Sarcoptiformes; Family: Sarcoptidae
- Size
- Microscopic; 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 (outermost layer) where they burrow.
Diet & Feeding
Dissolved skin cells and extracellular fluid found in the burrows they create.
Behavior Patterns
The female mite burrows into the skin to lay eggs, which hatch into larvae in 3-4 days. They are most active at night, causing intense itching. They spread via direct, prolonged skin-to-skin contact.
Risks & Benefits
Risks include intense itching (allergic reaction to mites/feces), secondary skin infections from scratching, and highly contagious infestations (scabies). There are no known benefits.
