That split-second of terror when you spot movement on your child’s scalp is universal, but it doesn’t have to own you. Lice, ticks, carpet beetle larvae, booklice, fleas—each sounds horrifying until you know what it actually does, how it behaves, and how quickly most of them can be handled with calm, simple steps. Identification is your superpower: a photo in good light, a saved specimen on tape, a quick call to a pediatrician or school nurse can turn chaos into a clear plan in minutes.
