They're Easy to Spot
Although lice and their nits are small, you can see them with the naked eye. They can be white, brown, or dark gray. You're more likely to find them in the hair at the back of your neck or behind your ears. The nits are round or oval specks that are tightly stuck to hairs near the scalp.
You may be able to see the lice, but they're often hard to spot because they're small, avoid light and move quickly. Lice eggs (nits) on hair shafts. Nits stick to hair shafts and may be hard to see because they're very tiny. They're easiest to spot around the ears and the hairline of the neck.
Once the eggs hatch, lice are known as nymphs, an immature form of the parasite that is grayish tan in color. After nine to 12 days the nymphs mature into adults, the average size of which is roughly 2–3 millimeters, or about the size of a sesame seed.
Head lice nits usually take about 8–9 days to hatch. Eggs that are likely to hatch are usually located no more than ¼ inch from the base of the hair shaft. Nits located further than ¼ inch from the base of hair shaft may very well be already hatched, non-viable nits, or empty nits or casings.
People with skin conditions such as seborrhea or psoriasis may have dandruff or scales on their scalp that attach to hairs. Unlike nits, though, you can brush these off the hair easily. A few people have hair that breaks in the center, giving off bristles that can make it seem as if something is attached.
Symptoms and Causes
The most common symptom of head lice is itching, especially on the back of your head and neck and near your ears — areas where lice are more likely to live. Symptoms of head lice include: Feeling like something in your hair is moving (tickling).
One is by direct head-to-head contact, as when children hug or put their heads together to look at the same book. The other way is by sharing hats, caps, hair ties, scarves, or any personal item such as combs or brushes. Body lice are spread by lice living on unwashed clothing.
Body lice frequently lay their eggs on or near the seams of clothing. Body lice must feed on blood and usually only move to the skin to feed.
How long do head lice and nits live on bedding and pillows? Considering the life cycle of lice and nits, it's possible to have live lice on a piece of bedding or pillow for up to 13 days. If a louse is without a host for 1-2 days, it will die.
Head lice survive less than one or two days if they fall off the scalp and cannot feed. Head lice eggs (nits) cannot hatch and usually die within a week if they do not remain under ideal conditions of heat and humidity similar to those found close to the human scalp.
They are small, oval-shaped, usually a yellowish-white color, and are firmly attached to the sides of hair shafts. The terms can be confusing because some people only use "nits" to refer to empty egg casings while "lice eggs" is used for eggs that can hatch (viable eggs).
Just like with mattresses, lice can only live on any bedding—whether it's sheets, pillows, or comforters—for 1-2 days. Without a human scalp as a source for food (blood) for longer than 1-2 days, lice cannot survive.
They bite anywhere they are feeding on the head, but they are particularly fond of the back of the head and the area behind the ears because this is a warmer area of the scalp. The bites often appear as small reddish or pink bumps, sometimes with crusted blood. When scratched excessively, the bites can become infected.
Vinegar contains properties that kill and get rid of nits and lice. This mixture should be applied directly to the whole scalp. Mix 1 cup of vinegar with 1 cup of warm water. Next, distribute this mixture onto the scalp and cover your hair with a hair cap.
If you see sesame-seed-shaped objects, those are the nits and lice, which can be brown or grey and stand out against the white paper towel. “The nits may look like they have tails that stick out the back,” says Faulkner.
Signs of head lice include itching and rash or redness around the neck, ears, and shoulders. As well as visible lice and nits upon inspection. Dandruff symptoms include white flakes that fall from the hair, oily or dry scalp, and scaly skin on the scalp.
If you've found yourself scratching your head lately, take a closer look. Dandruff will appear as white or yellow flakes of dry skin. Lice eggs, also known as nits, look like tiny yellow or white eggs in the shape of a teardrop. Adult lice are darker in color and about the size of a sesame seed.
A tickling sensation in the scalp
Not everyone feels lice moving around on their scalp, but some people do. Dr. Garcia says that most of her patients say they “don't feel anything,” but others may get a creepy, tickling sensation as lice move around their head.
Machine wash and dry clothing, bed linens, and other items that the infested person wore or used during the 2 days before treatment using the hot water (130°F) laundry cycle and the high heat drying cycle. Clothing and items that are not washable can be dry–cleanedORsealed in a plastic bag and stored for 2 weeks.
Items that can't be washed in the washer can be dry–cleaned OR be placed in a sealed plastic bag for 2 weeks. Soak combs, brushes, hair barrettes/clips/ties in hot water (130°F) for 5-10 minutes. Vacuum the floor and furniture, where the person with lice sat or lay.
Suffocate the Lice
Soak your child's head in olive oil or coconut oil. Cover with a shower cap for at least 2 hours (or preferably overnight). When ready, remove the shower cap, and separate the hair into small sections, then use a metal nit comb to carefully remove the lice and eggs. Rinse the hair well with shampoo.
The shampoo, cream rinse, or spray kills the live lice on the head but may not kill the nits. While the nits don't need to be removed from the hair, some people use a comb to remove nits after using lice treatment because they don't like the look of nits in the hair.
You can find head lice on the scalp, neck, and ears.
