The most common symptom of any type of lice is itching. Lice bites cause an allergic reaction that causes this itchy feeling. However, you may not feel itchy right away, especially if it’s a light infestation. You may not notice any symptoms for up to six weeks the first time you get lice.
In addition to intense itching, lice can cause other symptoms, such as:
- a tickling feeling of something moving on your head, hair, or body
- sores that develop from scratching itches
- difficulty sleeping
- red bumps on your head, neck, shoulders, or pubic area
- the appearance of lice eggs, or small white objects in your hair
