Head Louse

The human scalp and hair, remaining close to the skin for warmth and food.

Obligate blood-feeders that consume human blood several times a day.

Wingless insects that crawl but cannot jump or fly; they attach eggs (nits) firmly to hair shafts.

Cause intense itching and possible secondary skin infections from scratching; they are not known vectors of disease but are a significant social nuisance.
