look for signs of head lice (Figure 4). Feces — Look for lice feces on the scalp, which are tiny black specks. If you see them, examine the rest of the head for live lice. Eggs — Female lice typically attach eggs 1/4-inch from the scalp.
Also look for lice feces, that look like tiny black specks on your child's scalp. If you see black specks, care- fully examine the rest of the head for live lice. Eggs: Female lice typically attach eggs 1/2-inch from the scalp. There can be from a few to several hundred nits in a child's hair.
Adult head lice can survive up to two days away from the scalp, which is how they are transmitted by things like combs, brushes, and hats. During this whole life cycle, larvae and adult lice deposit their feces in the scalp, which eventually causes itching as the person develops an allergic reaction to the lice stool.
Be on the lookout for the following signs of head lice: An itchy head or crawling sensation on the scalp or hair. Small bumps or sores around the nape of the neck, behind the ears, or on the scalp. Black dried dots that look like grains of sand on the scalp.
For this you need to carefully comb the hair strand by strand with a fine comb. Every single nit needs to be removed. 3. Prevent re-infestation by washing towels, clothes, bedclothes and even fluffy toys in very hot water.

The most common symptom of pubic lice is itchy red spots. The itching is caused by an allergy to the louse saliva or poo. It can take 1 to 3 weeks for itching to develop after the first infestation, and it'll usually be worse at night.
About head lice and nits
Brown-black nits are eggs that haven't hatched into lice yet. White nits are eggs that have already hatched.
Some common bugs that can be mistaken for lice are ants, bedbugs, and fleas. A few things all these bugs have in common is they're small in size, can be dark colored, and can give you an itchy head. A few things that can be mistaken for lice nits are dandruff, hair product, or dirt.
Left untreated, head lice can lead to secondary infections, which can be serious. Bacterial infections, such as impetigo, can occur when scratched bites become infected; this can have serious consequences if not treated properly.
Lice move in dry hair and they may therefore be easier to spot, at least if there are many.
How soon do symptoms appear after exposure? Some people may not have symptoms, particularly with the first infestation or when the infestation is light. It may take 4-6 weeks for itching to appear the first time a person has head lice.
They can look like dandruff or dirt. To tell them apart, pull on the little speck with your fingers — dandruff and dirt can be removed, but nits stay stuck. A magnifying glass and a bright light can help with your inspection. The best way to check is by using a fine-tooth comb on wet hair.
Lice and dandruff can look the same at first glance, but they occur in different locations. Lice lay their eggs (called nits) on the hair shaft itself. Nits adhere to your hair and will not flake off like dandruff does. Nits are usually white or yellow and in the shape of a teardrop.
Black dots correspond to remnants of hair shafts in the follicular ostia and cannot be removed mechanically. They are usually associated with other forms of broken hairs. The second trichoscopic finding is hair dye; if hair is improperly washed, dye can deposit on the scalp and may even penetrate the follicular ostia.
Children can have a few nits without actually having a case of head lice. Usually children have no more than 10 to 20 live lice. Good lighting is important when you are checking. Head lice move fast and are hard to see.
Head lice eggs (nits) are brown or white (empty shells) and attached to the hair.
Dead nits are often black in colour and are found well away from the scalp. Nits are laid on the hair shaft within 1cm of the scalp and take about 7-10 days to hatch into head lice.
If nits are yellow, tan, or brown, it means the lice haven't hatched yet. If the nits are white or clear, the lice have hatched and just the egg remains. Lice eggs hatch within 1 to 2 weeks after they're laid.
Disinfectants are known for killing germs and bacteria. However, they are not an effective or safe treatment when it comes to killing lice and nits.
Itching. The most common symptom of head lice is itching on the scalp, neck and ears. This is an allergic reaction to louse bites. When a person has head lice for the first time, itching may not occur for 4 to 6 weeks.
