(HealthDay News) -- Lice are typically spread by direct head-to-head contact, and less often can be spread by sharing clothing or belongings such as backpacks, the U.S. Centers for Disease Control and Prevention says.

Once head lice fall from a host, they can survive for fewer than a couple of days, the agency adds.

The CDC suggests how to control the spread of head lice:

• Avoid head-to-head contact with an infested person.
• Do not share hats, scarves, coats, sports uniforms, hair ribbons or barrettes.
• Do not share combs, brushes or towels. Disinfect combs and brushes by soaking them for several hours in hot water (at least 130 degrees F).
• Avoid beds, couches, pillows, carpets, or stuffed animals that have recently been in contact with an infested person.
• Wash and dry in hot water clothing, bed sheets and other items that an infested person used.
• Items that are not washable can be dry-cleaned, or sealed in a plastic bag for two weeks.
• Vacuum the floor and furniture, particularly where the infested person sat or lay.
• Do not use fumigant sprays or fogs, which can be harmful to people.
