Scabies Mite (or Mange Mite)

Natural Habitat

The epidermis (outer layer) of skin in humans and other mammals; they are obligate parasites and cannot survive long off a host.

Diet & Feeding

They feed on skin cells and interstitial fluid as the female burrows through the stratum corneum of the epidermis.

Behavior Patterns

Females tunnel into the skin to lay eggs, creating 'burrows' (serpentine lines often visible on skin). The larvae hatch and create molting pouches. The primary symptom is intense itching, which is an allergic reaction to mite waste and eggs.

Risks & Benefits

Risks: Highly contagious, causes Scabies (intense itching, rash, sores from scratching), and can lead to secondary bacterial skin infections (like impetigo). Benefits: None; strictly a parasitic pest.
