Smarty pants. What do you do when you get hungry? Maybe you check the fridge or look in the pantry

or the snack drawer? Ooh, gummy worms. Or what about climbing onto a friend or family member's head

and sucking out some blood from their scalp? Hey, I'm using that blood. I know, I know, you're not a vampire.

And I know this because vampires aren't real. But there is a tiny creature that is very real who

does eat this way. Here, does this sound familiar? Ah, my head is so itchy. Here, let me look.

Oh no. What looks like you have... Lice. Lice? Wait, what's a Lice? Well, technically one is just a

Louse. Lots of them are Lice. Ah, carry on. Lice are tiny, wingless insects that live on your hair

and eat my hair. No, Foo, your head. Ah! Yep, according to most studies, one out of every 10

children will contract headlice at some point between the ages of one and eight years old.

But what exactly are Lice? Why do they love kids so much? And what's the best way to avoid or

get rid of them? It's time for another Itch of Science on... Headlice.

Hmm, particulars, humanists, capitals of the suborder, Therapeutura are essentially low-rent vampires.

An individual Louse, from a community of Lice, feeds on human blood from your scalp five to six

times a day in order to survive. And they are uniquely adapted for living in human head hair.

They need you. It's true. I love you and your delicious head.

Ah, I see we have a Louse in the house who's willing to talk.

So, tell me, Mr. Louse, how exactly do you suck someone's blood?
