Head-lice infestations and their treatment.

Head-lice infestations periodically cause disruption at schools and crèches. The life cycle of the insect and the treatment of infestation are discussed. Treatment is usually relatively simple and effective, relying mainly on the use of insecticides such as gamma benzene hexachloride, malathion and pyrethrins. Appropriate therapy for problem areas, for example the eyebrows, is also described.
