Lice are small, parasitic insects that feed on human blood. They are wingless and have six legs, and their bodies are flat and oval-shaped. Adult lice are about the size of a sesame seed, and they are gray or brown in color. Nymphs, or baby lice, are smaller and lighter in color.
Lice live on the scalp and feed on blood from the scalp. They lay their eggs, called nits, on the hair shafts close to the scalp. Nits are small, oval-shaped, and white or yellow in color. They are difficult to see with the naked eye, but they can be seen with a magnifying glass.
Lice can cause itching, redness, and irritation of the scalp. They can also spread diseases, such as typhus and trench fever. If you think you or your child has lice, it is important to see a doctor or pharmacist for treatment.

Small, parasitic insects
Lice are tiny creatures that can be difficult to see with the naked eye. They are about the size of a sesame seed, and they have six legs and a flat, oval-shaped body. Lice are parasitic insects, which means that they live on and feed off of other living organisms. In the case of head lice, the host is a human being.
- Crawling: Lice move by crawling. They do not have wings, so they cannot fly or jump.
Scurrying: Lice can scurry quickly through hair. This makes them difficult to catch and remove.
Blood-feeding: Lice feed on human blood. They pierce the skin with their sharp mouthparts and suck out the blood.
Itching: Lice bites can cause itching and irritation of the scalp. This is because lice saliva contains an anticoagulant that prevents blood from clotting. The anticoagulant also causes the skin to become inflamed.
Lice can be a nuisance, but they are not usually dangerous. However, they can spread diseases, such as typhus and trench fever. If you think you or your child has lice, it is important to see a doctor or pharmacist for treatment.
Wingless, six-legged
Lice are wingless insects, which means that they cannot fly. They also have six legs, which they use to crawl through hair. Lice legs are strong and claws at the end of the legs help them to grip onto hair shafts.
- Crawling: Lice move by crawling. They do not have wings, so they cannot fly or jump.
Scurrying: Lice can scurry quickly through hair. This makes them difficult to catch and remove. For this reason, it is important to use a fine-toothed comb to remove lice and nits from hair.
Head Lice: Head lice live on the scalp and feed on blood from the scalp. They can cause itching, redness, and irritation.
Body Lice: Body lice live on clothing and bedding. They can also feed on blood from the skin. Body lice can cause a condition called vagabond's disease, which is characterized by intense itching and skin lesions.
Lice can be spread through head-to-head contact, sharing combs or brushes, or wearing infested clothing or bedding. It is important to take steps to prevent lice infestation, such as avoiding contact with infested people or objects, and washing clothes and bedding in hot water.
Flat, oval-shaped bodies
Lice have flat, oval-shaped bodies. This shape helps them to move easily through hair and clothing. Lice bodies are also very tough, which makes them difficult to crush.
- Crawling: Lice move by crawling. Their flat bodies help them to move easily through hair and clothing.

Lice can be a nuisance, but they are not usually dangerous. However, they can spread diseases, so it is important to treat lice infestations as soon as possible.
Eggs (nits): small, oval, white or yellow
Lice eggs, also known as nits, are small, oval-shaped, and white or yellow in color. They are about the size of a grain of sand. Nits are attached to hair shafts close to the scalp. They are difficult to see with the naked eye, but they can be seen with a magnifying glass.
Nits are laid by adult female lice. A single female louse can lay up to 10 eggs per day. Nits hatch into nymphs, or baby lice, in about 7-10 days. Nymphs mature into adult lice in about 10 days.
Nits can be spread through head-to-head contact, sharing combs or brushes, or wearing infested clothing or bedding. It is important to take steps to prevent lice infestation, such as avoiding contact with infested people or objects, and washing clothes and bedding in hot water.

Nits can be difficult to remove from hair. It is important to use a fine-toothed comb to remove nits from hair. You may also need to use a medicated shampoo or lotion to kill any remaining nits.
Nits attached to hair shafts, near scalp
Nits are attached to hair shafts close to the scalp. This makes them difficult to see, especially if the hair is dark-colored. Nits are also very small, so they can be difficult to see even with a magnifying glass.
Nits are attached to hair shafts by a glue-like substance. This glue is produced by the female louse when she lays her eggs. The glue helps to keep the nits in place, even when the hair is washed or brushed.
Nits can be spread through head-to-head contact, sharing combs or brushes, or wearing infested clothing or bedding. It is important to take steps to prevent lice infestation, such as avoiding contact with infested people or objects, and washing clothes and bedding in hot water.

Cause itching, redness, irritation
Lice bites can cause itching, redness, and irritation of the scalp. This is because lice saliva contains an anticoagulant that prevents blood from clotting. The anticoagulant also causes the skin to become inflamed.
Lice bites can also lead to sores on the scalp. These sores can become infected, which can lead to further complications.
In some cases, lice can also cause a condition called pediculosis capitis. Pediculosis capitis is a skin condition that is caused by an allergic reaction to lice bites. Symptoms of pediculosis capitis include intense itching, redness, and swelling of the scalp. In some cases, pediculosis capitis can also lead to hair loss.
