Elimilice answers the question why head lice seem to be everywhere.
Why does it seem like head lice are everywhere?
In August 2010, the American Academy of Pediatrics' Council on School Health produced its first report on head lice since 2002. The updated document noted increased patterns of resistance among head lice to over-the-counter products designed to kill them and their eggs.
Although head lice never disappeared in United States, their prevalence was once so low – because of widespread use of DDT (until its ban in 1972) that many children growing up during the "Baby Boom" years had no concept of head lice outbreaks.
