Scabies Mite

Natural Habitat

The epidermis (top layer) of human skin, particularly in folds found between fingers, wrists, armpits, and genitals; can survive briefly (2-3 days) on bedding or clothing.

Diet & Feeding

Feeds on dissolved human tissue and lymph found within the burrowed skin tunnels.

Behavior Patterns

The female mite burrows into the upper layer of the skin to lay eggs, creating serpentine, tunnel-like tracks (burrows) visible to the naked eye as shown in the image. The larvae hatch and travel to the skin surface to molt.

Risks & Benefits

Risks: Causes scabies, an infestation characterized by intense itching and a pimple-like rash; scratching can lead to secondary bacterial infections like impetigo. Benefits: None; they are strictly parasitic to humans.
