Lice are a tiny parasitic insect that can be found on people's heads and bodies. Infestations spread most commonly by close person-to-person contact. Pets do not play a role in the transmission of human lice. There are both over-the-counter and prescription medications available for the treatment of lice.

Lice
What are head lice?
Lice Page 1Human head lice (Pediculus humanus capitis) are sesame seed sized parasitic insects that are usually gray, brown, or black in color. Head lice infests the hair on people’s heads and necks, and rarely on their eyebrows and eyelashes. 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.
Who is at risk for getting head lice?
Head lice are found worldwide. Each year millions of school-aged children in the United States get head lice. It is most common in preschool- and elementary school-aged children. However, anyone can get lice, like household members – including adults - of infested children.
How do head lice spread?
Head lice are crawling insects, they do not jump, hop, nor fly. The most common route of spreading lice is from direct contact with the hair of an infested person. There is a very small chance that head lice will spread by sharing personal items such as combs, brushes, hats, or sports helmets. A person’s hygiene or cleanliness of their home has nothing to do with getting head lice.
What are the symptoms of head lice?
  • Itching is the most common symptom. Head lice saliva becomes irritable to the scalp, making the individual’s head feel itchy.
  • “Tickling” or a sensation of something moving in the hair.
  • Seeing white/yellow lice eggs, called nits, attached to individual hairs close to the scalp.
  • Irritability and sleeplessness. Lice are most active at night, causing heighted itching and tickling sensations.
  • Sores on head caused by scratching the scalp.
How do you check for head lice?
  • Seat the individual in a brightly lit room.
  • Part their hair and begin to examine the head. Examine very close to the scalp, one section at a time.
  • A fine-tooth comb, or a specific nit comb, can assist with searching each section.
  • lice 2Look for live crawling lice and for nits - white/yellow lice eggs, attached to individual hairs.
    • Live lice may be hard to find as they move quickly and avoid light.
    • Nits can be differentiated from common dandruff, dirt, or hair product particles by examining if they are firmly attached to the hair.
