Get to know the facts of lice so you are equipped to do battle if or when your kids get them.

  • Head lice are bugs about the size of a sesame seed or smaller. They have six legs with tiny claws, no wings, and live only on human scalps.
  • Head lice and nits (eggs) range in color from light brown to dark brown. On the scalp, they appear translucent with a brown tint; when placed against a white background, they are brown.
  • Lice (bugs) are difficult to spot because they run (quickly) to the dark as they eschew light.blurry microscope image of single adult louse
  • Nits (eggs) are teardrop shaped—round on one end and pointy on the other.
  • Nits are cemented to the hair close to the scalp and have to be pulled off.
  • Both nits and lice tend to camouflage in the hair particularly in brunettes.
  • Lice are extremely contagious and deposit 6-10 eggs per day per louse.
  • Each louse can live for 30 days and may leave 200 eggs in the hair over its lifetime.
  • Head lice feed on human blood from the scalp up to 3 times a day and they will die within a day if they are not on the head.
  • Unhatched nits are not contagious and if a nit manages to fall off the hair, it can not reattach to the hair.
  • The incidence of lice and the severity of the cases have increased over the past several years due to the growing resistance among these insects to the chemical shampoos.
  • Today’s lice are so hearty/resistant as to be dubbed “super lice".
  • By far the most common way to contract lice is from head to head contact; it is possible but less likely to get lice from an object like a brush, helmet, or backpack.
