Lice --Where Do They Come From?

Head Lice apparently have been around for more then 100,000 years! Head lice are no longer  a source of disease, but they are a social issue. I found this Reuters Health and Science article fascinating. It help to prove the point that the only way to manage head lice is to remove each and every nit and louse and no chemicals or heat treatments are ever going to be completely effective. Head lice are very adaptable.
