Louse Nit

Natural Habitat

Found exclusively on the human host, typically glued to hair shafts near the scalp.

Diet & Feeding

Does not feed in the egg stage; adult lice feed on human blood.

Behavior Patterns

Nits are eggs laid by female lice and are firmly cemented to hair strands. They hatch in about 7-10 days into nymphs.

Risks & Benefits

Causes head lice infestation (pediculosis), which leads to intense itching and secondary skin infections from scratching; no known ecosystem benefits.
