Often red bite marks or scratch marks can be seen on the scalp and neck. In severe infestations, a child may develop swollen glands in the neck or under the arms. Pediculosis can be spread as long as lice or eggs remain alive on infested persons or clothing. Usually light brown, the color can vary. They move quickly, and shy away from light which makes them difficult to see.
Nits are tiny, yellowish-white oval eggs attached to the hair shafts.
A magnifying glass and natural light may help when looking for them. Safety first when using pesticides. All lice-killing products are pesticides and must be used with caution. Before one family member is treated, all members should be examined. Everyone should be treated at the same time to prevent re-infestation from one family member to another.
