CARL SMITH: If I say the words head lice, does your head start to feel a bit itchy? Thankfully, these guys don't actually have any. But in case they do run into them, we thought we might clear up a few questions they had about those annoying little bugs.
STUDENT 1: What are lice and why do they make you itchy?
SMITH: Lice are creepy little parasites that live on your scalp and cling to your hair. They feed on your blood. And it's their bites that caused that irritating itchy feeling.
STUDENT 2: What's the difference between nits and lice.
SMITH: Lice are the bugs and nits are their eggs. The term lice is actually the plural of the word louse. And the word "lousy" used to mean being infested with lice. But now we use it to describe something bad, which is how most people feel when they discover they've got lice.
STUDENT 3: Can you catch lice from other people?
SMITH: Lice move between people all the time. But they can't fly or jump, so head to head contact with someone is the most likely way to catch them. Pets or using the same furniture as someone with lice aren't as likely to spread them because the bugs need to stick close to their food source, us.
STUDENT 4: If I get head lice, does that mean I'm not keeping clean or that my hair is too long?
SMITH: Absolutely not. Anyone can catch head lice, no matter how clean your hair is. The length of your hair doesn't make much difference either, although lice are easier to remove from short hair.
STUDENT 5: Surely they are pretty easy to get rid of.
SMITH: Lice are tiny, fast, and they breed quickly. This is one of the most common ways we get rid of nits, using conditioner to stop them and a fine tooth metal comb to pull out the lice and their eggs. But miss just one egg and you'll have heaps crawling around again in no time.
STUDENT 6: Do those medical shampoos work?
SMITH: Medical shampoos have chemicals in them that are poisonous to lice. But lately, they haven't been working as well as they used to. That's because lice are developing ways to survive them. A new study from the US found almost every state there had resistant lice. These new superbugs are born with special traits that stop the usual chemicals from killing them. So experts are worried that soon medicated shampoos could stop working completely.
STUDENT 7: My Mum says things like Vaseline, oil, and mayonnaise can help get rid of them. Is that right?
SMITH: Well, some people say they work. But there's not a lot of science to back this up. Some experts say that mayonnaise could theoretically work, but only if you use heaps and heaps of it. I don't know if this is really any better than just having nits.
STUDENT 8: Will they make me sick?
SMITH: Thankfully, lice don't carry diseases. So although they might be annoying and really itchy and frustrating to get rid of, at the end of the day, these little bloodsuckers won't leave you with anything to worry about.
