Head lice, despite their miniscule size, are visible to the naked eye. The adult louse is as large as a sesame seed and has a brownish tan color. Once they hatch, nymphs become adult lice in only 7 days. Every 4 to 6 hours, most lice nourish themselves with blood. Head lice can live and thrive off of the scalp for up to 3 days before they expire.

These bugs can quite easily jump between individuals, particularly in close quarters such as a classroom. Lice are small and have evolved with pointed ends which result in their spreading. Despite the fact they are unable to move through the air, they can transmit through even casual contact. This is made worse by loaning personal grooming items, as is common in elementary schools.

You can kill lice and lice eggs with lice treatment medications. The itch won't stop for several days. You should redo any treatment in eight or ten days to ensure every egg or nit has been destroyed to make sure they never recur another time.
