Scabies Mite

Natural Habitat

The specific habitat is the epidermis (upper layer) of human skin, where females burrow to lay eggs. They are obligate parasites.

Diet & Feeding

They feed on human skin cells and fluids found within the epidermis.

Behavior Patterns

The primary behavior is burrowing into the stratum corneum of the skin to create tunnels (visible as fine, wavy lines) where the female lays eggs. The lifecycle from egg to adult takes about 2 weeks. They are most active at night, which correlates with intense itching.

Risks & Benefits

Risks: Highly contagious skin infestation causing intense itching (especially at night) and a pimple-like rash. Secondary bacterial infections (like impetigo) can occur from scratching. Benefits: None known; they are parasitic pests.
