Where Do Lice Come From?


♪ Hi, Squeaks, how’s it going? [Squeaks squeaks] Oh, I’m doing all right, and I’m really
glad my head isn’t itchy anymore. [Squeaks squeaks] Well, actually, I had head lice last week,
but it’s gone now! Lice are little tiny bugs that like to live
in people’s hair. And they’re really itchy! [Squeaks squeaks] Don’t worry! Head lice can’t make you sick! And it’s really unlikely you’d get head
lice because head lice don’t jump from person to person – or from person to robot rat! The only way you’d get it is if we shared
a hat, a hairbrush, a pillow, or anything else that might touch my head. I remember not too long ago, I tried on my
friend’s cool hat – and it turned out she had head lice. So I bet that’s where I got it from! Anyone can get lice, and it doesn’t mean
they’re dirty or don’t shower enough. Lice actually have an easier time living on
clean hair — it’s not as slippery, so it’s easier for them to grab onto. The only thing head lice are interested in
is your scalp — the skin underneath your hair. All head lice want is to bite your scalp so
they can feed off your blood. Ick, I know! They’re a little like mosquitos that way
since they feed off your blood, too. But unlike mosquitos, which can bite pretty
much anyone, kids get head lice more often than adults, mainly because kids share hats
and brushes a lot more often than adults do. So what exactly was going on in my hair? Let’s take a closer look! A louse, which is the word for one lice, has
six legs, with claws on each leg! They use these claws to hold onto your hair! Lice are pretty tiny, about the same size
as a strawberry seed or a sesame seed. When a louse first gets into your hair, it
lays eggs, called nits. The louse also makes something a lot like
glue, which makes the nits stick to your hair. Weird, right? Then, after about eight or nine days, the
nits hatch! These young lice are called nymphs. After about 9-12 more days, the nymphs grow
up and become adult lice. Most people don’t start itching until 2-6
weeks after they get lice, though. And some people actually don’t itch at all! But It’s definitely important to get rid
of the lice. Not only is it kinda icky, and having an itchy
scalp is pretty annoying – but also, if you scratch too much, you could hurt the skin
on your scalp and even get an infection if the skin breaks open and germs get in. Sometimes people can mistake other things
like dandruff or dirt for head lice, so the first thing to do is be sure you have lice
by talking to an expert. A nurse or other lice expert will look closely
at your scalp. They might comb through your hair with a fine-toothed
comb that can catch the lice. They might also use a special light called
a blacklight, which glows a kind of dark purple and helps you see lice more easily. If you do have lice, they might recommend
you use a special shampoo that helps get rid of the lice. Usually they say you should use the special
shampoo again a little over a week later, because even if the shampoo gets rid of all
the lice that are already alive, it might not get rid of all the nits — the lice eggs. So when those nits hatch, the shampoo can
get rid of the lice that come out of them before they have a chance to lay even more
eggs. Cool fact, a lot of these shampoos are made
from the chrysanthemum flower! It has chemicals in it that will kill lice. You may not need to see a doctor or nurse,
but you should definitely tell an adult if your head is itchy, and they can decide. If you have lice, you may be able to treat
it at home by combing your hair with a special comb or using a special shampoo — or doing
both! You’ll probably also need to wash your bed
sheets and any clothes you wore in the last two days in hot water. And if you have a favorite stuffed animal
– and who doesn’t? It will probably need to go in the dryer just
to be sure it doesn’t have any lice, either! And that’s pretty much it! So, Squeaks! I sure am glad I got my head lice taken care
of! When you’re experiencing something weird
like itching, it’s always good to tell someone. And it’s also good to know that it’s really
nothing to worry about. Having head lice definitely isn’t fun, but
they’re also pretty harmless, and there are ways to get rid of them. Thanks for joining us! If you want to keep learning and having fun

  1. Two ways I prevent lice
    1: Get a shampoo, hairspray, or gel or other products that prevent lice
    2: Don’t share hairbrushes, hats, and pillows

  2. When explaining that head lice don't indicate poor hygiene, it might have been good to mention that the term "lousy" for "bad" derives from the same word, perpetuating the stigma.

  3. My 7 year old daughter has the following question, Why does my tongue become numb after I eat a lemon? Thank you for your help in advance.

  4. 😱😱😱😱😱😱😱😱😱😱😱😱😱😱😱

  5. I’m Asian I heard that lice really doesn’t like it so yeah! But you know! Also my homeroom teacher, she got lice on Easter Day during college last year, she is very young, I won’t say her age, but yeah! Last year on a Special Holiday! (Jesus rises from the dead!) the rising dead!

  6. She forgot to mention lice are racist they don't go to black people(such as me) as often cause it hard for them to hold our hair since we usually have braids and etc so yeah

  7. I'm crying I have many lice and it won't go away I'm tired of my lice and I just Wanner die😫😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭i hate lice

  8. So I have head lice and you take them out by putting on conditioner on your hair and then leave it on for 10 minutes and then use a special comb. Next all your head lice is out but they can breathe for 8 hours so put some clothes on your hair and then wait for 10 minutes again and then put it in the washing machine.

  9. That’s right they suck your blood and you might not take them all out so use conditioner first and then comb it
