When a lab asked teachers, parents, and school nurses to send in samples of lice or nits, only 32% were evidence of an infestation. (Doctors did worse, with only a 10% success rate.) The rest were dandruff or dirt mistaken for nits, or random insects that kids had picked up in the backyard — gross, perhaps, but nothing a quick shower won’t fix.

That’s why the American Academy of Pediatrics says:

Never initiate treatment unless there is a clear diagnosis with living lice.

There’s no need to send kids home from school or cover their heads with pesticides unless you’re sure there’s a population of lice having a party on your kid’s head. Over at Slate, Melinda Wenner-Moyer explains how believing a casual lice diagnosis is just the first of a series of mistakes parents and school staff often make; check out the full article for more.
