Who Is At Risk Of Getting Head Lice?
Head lice are all over the world. However, in the United States, they're most commonly found among pre-school children who attend child care or children in elementary school, along with the household members of the children who are infested.
What Do Lice Look Like?
Head lice are in three forms known as the egg (also referred to as the nit), the nymph and the adult.
-
Eggs are laid by female lice at the hair shaft base near the scalp. Eggs, also known as nits, are tiny, oval-shaped and difficult to see. They're often yellow or white but can also be the same color as your hair. Nits take about eight to nine days to hatch.
-
A nymph is an immature louse that is hatched from the nit. They are smaller than adult lice and feed on blood. After nine to twelve days of maturation, they will be adults.
-
An adult is a fully grown and developed louse around the same size as a sesame seed. They have six legs and are tan to grayish-white in color. Some may appear darker in person if the individual has darker hair. Adult lice feed on blood and live around 30 days until they fall off the head and die in one to two days. Females are typically larger than males and can lay up to six eggs each day.
Where Are They Often Located?
They are found almost always on the scalp, around and behind the ears and near the neckline at the back of the head. They hold a tight grip on hair with their hook-like claws and are difficult to remove.
What Are The Signs Of A Lice Infestation?
If you're experiencing tickling, movement, itching and sores on your head, you most likely have lice. Irritability and sleep loss are also common, as they're most active in the dark.
