Scabies Mite
Scientific Name: Sarcoptes scabiei var. hominis
Order & Family: Order: Sarcoptiformes; Family: Sarcoptidae
Size: Microscopic; females are 0.30–0.45 mm long, males are significantly smaller (0.25–0.35 mm). Usually invisible to the naked eye.
Natural Habitat
The epidermis (outer layer) of human skin, particularly in folds and crevices like between fingers, wrists, elbows, and waists.
Diet & Feeding
Feeds on human skin cells and lymph fluid found within the epidermis.
Behavior Patterns
Female mites burrow into the upper layer of the skin to lay eggs, creating visible, raised, serpentine 'tunnels.' They are most active at night, which is when the intense itching usually worsens.
Risks & Benefits
Risks: Highly contagious skin infestation causing intense itching (pruritus) and rash. Secondary bacterial infections (like impetigo) can occur from scratching. Not beneficial to humans or the immediate ecosystem.
