What Are Symptoms of Lice?

Symptoms of Head Lice

Lice are tiny insects that can be found on various parts of the body, including the head, eyebrows, and eyelashes. These insects live on humans and feed on their blood. Lice that live close to the scalp are known as head lice.

  • The most common symptom associated with head lice is itching. This is caused by an allergic reaction to the bites of the head louse. However, it may take some time for itching to develop.
  • Scratching behind the ears or the back of the neck is a sign that you should check for head lice.
  • Scabs or blood spots may be seen
  • Irritability
  • Difficulty sleeping since head lice are most active in the dark
