Human Itch Mite / Scabies Mite
Scientific Name: Sarcoptes scabiei var. hominis
Order & Family: Sarcoptiformes; Sarcoptidae
Size: Microscopic; adult females are approximately 0.30–0.45 mm long and 0.25–0.35 mm wide, often barely visible or resembling a tiny speck of salt or dandruff to the naked eye.
Natural Habitat
The upper layer of human skin (epidermis). They burrow into the skin to live and deposit eggs.
Diet & Feeding
Tissue fluids and skin debris from the host.
Behavior Patterns
These mites burrow tunnels under the skin, especially in folds (between fingers, wrists, armpits), causing an intense allergic reaction and severe itching, particularly at night. The life cycle from egg to adult takes about 10-14 days.
Risks & Benefits
Risks: Highly contagious and causes Scabies, a skin infestation characterized by relentless itching and pimple-like rashes. Secondary bacterial infections (like impetigo) can occur from scratching. Benefits: There are no known benefits to humans or the domestic ecosystem.
