  • Head Lice Facts One adult louse can lay 10 eggs or nits a day and live up to 30 days!
  • Nits hatch in 7 to 10 days. The immature louse is called a nymph.
  • The nymph matures to an adult in 7 to 10 days (2-3 week life cycle).
  • Lice do not fly or jump. They crawl.
  • Lice can survive a day without a host but usually not longer than 48 hours.
  • Itching is the most common symptom, but may not occur until one week after infestation. Up to 50% may not itch at all.
  • Age, hygiene, blood type, blow-drying and hair treatments (coloring or permanents) do not prevent infestation!
  • Nits are teardrop shaped and tightly attached to one side of the hair shaft.
  • Nits need constant heat and moisture to mature.
  • Each strand can have more than one nit.
  • Nits found further down the shaft can be alive.
  • Nits are commonly found on the top of head, above ears and nape of neck but check the entire head.
  • Head lice only live on a human head. Pets do not carry human head lice.
