Pediculus humanus capitis
The head louse, or Pediculus humanus capitis, is a parasitic insect that can be found on the head, eyebrows, and eyelashes of people. Head lice feed on human blood several times a day and live close to the human scalp. Head lice are not known to spread disease.
Head lice are most common among primary school aged children and are spread by direct contact with the hair of the infested individual. Head lice are rarely transferred through clothing, hats, furniture or bedding.
