Itch Mite or Scabies Mite
Scientific Name: Sarcoptes scabiei
Order & Family: Sarcoptiformes / Sarcoptidae
Size: Microscopic; females are approximately 0.30 to 0.45 mm long, while males are about half that size.
Natural Habitat
Human skin, specifically within the stratum corneum (the outermost layer of the epidermis).
Diet & Feeding
They feed on dissolved skin cells and extracellular fluid.
Behavior Patterns
Microscopic mites burrow into the skin to lay eggs. This activity triggers an allergic-like reaction that causes intense itching, especially at night. They are transmitted through direct, prolonged skin-to-skin contact.
Risks & Benefits
Risk: Causes Scabies, a contagious skin infestation characterized by severe itching and rashes. If left untreated, scratching can lead to secondary bacterial infections like sores or impetigo. There are no ecological benefits to humans.
