Human Head Louse (Nit/Egg stage)

Found exclusively on the human scalp and hair shafts, typically close to the skin for warmth.

Obligate parasites that feed on human blood multiple times a day.

Nits are glued firmly to hair shafts. They cannot fly or jump; transmission occurs through direct head-to-head contact or sharing personal items.

Causes intense itching and scalp irritation. They are not known to spread diseases, but secondary skin infections can occur from scratching.
