Head Louse

Human scalp and hair, most commonly found near the neckline and behind the ears.

Obligate ectoparasites that feed exclusively on human blood several times a day.

Wingless insects that cannot jump or fly; they move by crawling. They cement their eggs (nits) to the base of hair shafts.

Cause intense itching and possible secondary skin infections from scratching; however, they do not spread bacterial or viral diseases.
