NitsPediculosis is an infestation of lice from the sub-order Anoplura, family Pediculidae. Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis.https://en.wikipedia.org › wiki › Pediculosis
New eggs are attached to the hair shaft very close to the scalp. Eggs that still contain a louse embryo are brownish in color, while the empty egg shells are white to grey.
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.
They are very small and will be a dark golden-brown colour if they are about to hatch or are white if the louse has already hatched and left the egg. If they are full then they will be plump and shiny. What does a dead lice egg look like? A dead lice egg will be white or grey.
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. If you try to slide them off, they won't budge.
It's not uncommon to find nits in your hair without live lice. If you find only nits, you should still treat your hair as if you have lice. You should also avoid close contact with other people and sharing hats or brushes until you no longer see nits or lice in your hair.
Adult Head Lice: When lice reach adulthood, their color darkens in response to their environment. Those with blonde or light brown hair are more likely to have tan or light brown adult lice. Darker Head Lice: You'll typically find dark gray to black lice for those with black hair or dark skin.
Nits that are attached more than ¼ inch from the base of the hair shaft are almost always non-viable (hatched or dead). Head lice and nits can be visible with the naked eye, although use of a magnifying lens may be necessary to find crawling lice or to identify a developing nymph inside a viable nit.
Check if it's head lice
They can be difficult to spot in your hair. Head lice eggs (nits) are brown or white (empty shells) and attached to the hair.
These look like tiny yellow, tan, or brown dots before they hatch. Lice lay nits on hair shafts close to the scalp, where the temperature is perfect for keeping warm until they hatch. Nits look a bit like dandruff, but aren't removed by brushing or shaking them off.
Live lice eggs are small brown or tan coloured dots on hair shafts close to the scalp. These can be incredibly difficult to spot. Broken egg shells, or nits, are easier to spot.
Comb dead and any remaining live lice out of the hair using a fine–toothed nit comb. If, after 8–12 hours of treatment, no dead lice are found and lice seem as active as before, the medicine may not be working.
Infestation timeline
So if you look on the scalp and see no visible adult lice and several small nits, it's likely that you've caught lice in the earlier stages and had them for less than 2 weeks. Nits and nymphs: 1.5 to 2 weeks. If you see nits and small, moving lice, you've likely had lice for 1.5 to 2 weeks.
Only live lice can give lice to another child. Nits (lice eggs) cannot pass on lice. Nits are attached to the child's hair.
Adults: The adult louse is about the size of a sesame seed, has 6 legs (each with claws), and is tan to grayish-white. In persons with dark hair, the adult louse will appear darker. Females are usually larger than males and can lay up to 8 nits per day.
Only one live bug can be produced per nit or egg. After the egg is laid, it takes roughly seven to 10 days for it to hatch. Once the egg hatches, it takes another seven to 10 days to reach maturity and begin laying eggs of its own. An adult louse can lay up to six eggs per day and live for up to 30 days on a host.
Lice eggs (called nits) look like tiny yellow, tan or brown dots before they hatch. If you pull one off the hair, it may look like a flat speck with a tiny tail (which is the residue of the hair shaft it was glued to). After hatching, the remaining nit shell looks white or clear.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
Lice and nits can live on pillows and sheets. Lice glue their eggs to the hair strands of their host. However, if a piece of hair with an egg falls out while the lice host is sleeping, an egg could end up on pillows or sheets.
Life Cycle:
Nits take about 1 week to hatch (range 6 to 9 days). Viable eggs are usually located within 6 mm of the scalp. ) and become adults about 7 days after hatching. .
But unfortunately, the nits will not simply fall out your hair. The lice themselves take 7 to 11 days to hatch, so after that what is attached to the hair is the empty eggshell or the dead nit. These will stay attached to the hair and as the hair grows you will find them further and further down the hair shaft.
They begin around the size of the head of a pin and get larger each time they molt — or shed their skin.
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.
When lice first hatch from their eggs, they're called nymphs, and they look just like adult lice but smaller, about the size of a sesame seed. The babies are clear in colour for the first few hours. “You can see right through them, so it's very difficult to see them in your hair,” says Faulkner.
Adult: The fully grown and developed adult louse is about the size of a sesame seed, has six legs, and is tan to grayish-white in color. Adult head lice may look darker in persons with dark hair than in persons with light hair.
