What are lice?
Lice are tiny dandruff-like insects on the head, they live and grow by sucking a small amount of blood from the scalp, then lay eggs in the hair.Lice are easily spread on the body or clothes and cause dermatitis (redness, itching, swelling) which bring a lot of discomforts. The blood-sucking insects are multicolored, ranging from brown to reddish-brown and surprisingly, they just like to be friends with humans. Lice have no wings, so they cannot fly or jump from one head to the other, they can only crawl.
Lice live only in human hair and only “illegally immigrate” into the scalp to get blood. Therefore, they are not “alarming” by making you feel itchy at the early stage. Therefore, only when the lice have grown a lot on the head and can be seen easily, then you can notice and start to worry about their existence.
How long does it take for nits to hatch?
Lice will stick to the hair, about 1cm from the scalp, with an oval and small shape like a pin. They lay eggs at about 2.5cm from the scalp – this place is both soft and warm – suitable for hatching eggs. So, how long does it take for nits to hatch? Lice eggs will hatch within 7-10 days and female lice can lay 150-300 eggs so it is not surprising that in a short period of time a few lice can create “troops” a few hundred lice eggs
After hatching, the white or yellow eggshell is still attached to the hair, “leaving” the scalp layer as the hair grows every day. As a result, the shells that are not attached to the hair are often found to be quite far from the scalp where the head lice are actually living. The baby lice are not much larger than the eggs and are usually light in color. 9-12 days later, they become mature, then match with other lice, female lice lay eggs and the cycle continues.
The lifespan of lice lasts about two months long. During that time, the female lice lay a lot of eggs but only about 50% of them can hatch. Also, depending on the blood and body temperature of each person, lice can be easier to grow in some people than others. Head lice can move from one’s head to another when the temperature is not appropriate. So that, the answer for the question of How long does it take for nits to hatch can also depend on each people, ranging from a week to about 11 days. Usually, girls are more prone to have more head lice than boys as their hair is longer.
Prevent the spread of lice
Once a person with lice has been identified, the best way to prevent the spread of lice is to remove the lice completely on the head. Moreover, limiting hair exposure to other people’s hair is also helping significantly to minimize the spread and penetration of lice to the new “host”. You should also remember after reading the above part which is about How long does it take for nits to hatch, that lice egg can hatch in a quite short period of time. Therefore, it is recommended that you should put all efforts to end this problem as soon as possible.
Another cause (though less common) that leads to lice spread is the sharing of clothing and accessories such as hats, combs, and other hair accessories. People with head lice should avoid sharing a bed with siblings or friends. And a more contagious pathway is rarer: lice can “move” from one person to another through the bed or some contaminated furniture. And again, how long does it take for nits to hatch? Very soon after that, there will be more people who get into trouble with lice.
