The Facts of Lice

 by Abigail Rosenfeld


  • It is possible for anyone to get head lice.

  • Lice are about the size of a sesame seed and they can lay up to 300 nits (eggs) or 3-10 per day once they find a host

  • Lice lay nits, which are small, tear-shaped, and vary in color from beige-to-dark brown.

  • Head lice are parasites that survive off human blood. Therefore, they are attracted to the scalp and generally cause itching when they bite like other insects.

  • Although lice are not known to carry diseases, lice can cause bacterial infections when someone scratches a bite with a dirty finger.

  • Nits take about 7-to-10 days to hatch and need a human host to survive. Items that cannot be washed must be bagged for two weeks to ensure the nits will die after they hatch.

  • Lice do not jump or fly. They only crawl and spread from person-to-person by direct contact or by shared hats, brushes, clothes, etc.
  • Head lice enjoy a clean environment,so don't assume you are dirty if you contract them.

  • To get rid of head lice, several steps must be taken:
  1. Check everyone in the family, so no nit is missed.
  2. Everyone who has lice/nits must be cleaned out. Manual removal is the safest and most effective method to eradicate lice.
  3. The house must be cleaned properly.

The process of getting rid of lice can be extremely overwhelming for all those involved. The stress can be greatly reduced by calling for help from a professional.
