Why Are Head Lice Called Nits?

Head lice are small, wingless insects that feed on blood from the scalp. They are most often found near the hairline and behind the ears, but they can also be found on the eyebrows and eyelashes. Infestations of head lice can cause a person to experience itching. The excessive scratching can cause sores on the scalp, which can become infected and red. If they are removed, head lice die within two days.

People who share clothing or bedding with a person with head lice are at greatest risk for infection. This is because lice move by crawling and spread through close person-to-person contact. There are no direct precautions for preventing head lice, but good personal hygiene can prevent lice from spreading.

Using a non-prescription product is the best way to treat head lice. This product will kill the lice and their eggs. It is important to follow the instructions on the label to ensure you are using a product that is safe for your child. You should also check all members of the household for head lice. If you suspect that your child has lice, it is important to seek medical care immediately. A doctor can confirm the diagnosis and recommend a treatment.

Lice are tiny insects that live in the scalp. They feed on human blood and lay their eggs in the hair near the scalp. The eggs are not visible because they are covered in a glue-like substance. These bugs tend to affect young children, but they can also infect adults living in close proximity to children.
