Lice can also be contracted by sharing tools such as brushes, combs or towels with someone with an infestation.
And they are most common in elementary school children who pass the bugs to each other while playing.
These little critters can fly to jump from person to person, so if a child is infested with lice, the rest of the family probably will be too.
Symptoms include extreme itching of the scalp, a crawling sensation over the scalp, and sores or scabs on the scalp from scratching.

If left untreated, these nits can multiply by the tens of thousands.
