Head Lice

Head Lice Placeholder Image
  • Human head lice (Pediculus humanus capitus) have been associated with humans for thousands of years.  Head lice are minute (about the size of a sesame seed), wingless parasitic insects that must live on a person to survive.  They survive by piercing the skin to feed on blood and are almost exclusively associated with hair on the neck and scalp.  The majority of head lice infestations occur by direct head-to-head contact with an infested person.  Most of the time this is a close friend or relative.
