This
section contains actual photographs of head lice & their
eggs (nits), plus factual information to correct some common
myths & misconceptions surrounding head lice.
What
do they look like?
Most
pamphlets you pick up on head lice will have nice, friendly
cartoon pictures of head lice, or no pictures at all. We've
included some enlarged pictures of actual lice & nits,
so you know what you're looking for:
 |
Head lice
are usually white to grey in colour, with a dark stripe
down the centre of their body. They are about the size
of a sesame seed (approx. 2mm), with six legs &
two "spiracles", or antennae, on their head.
As they can run away, they are usually harder to find
than nits. |
| Nits
are the eggs of head lice. They are usually oval-shaped,
little bigger than a pinhead (approx. 1mm) & cream
to coffee in colour. "Fresh" or newly laid
nits are found next to the scalp at the base of the
hair shaft. |

Now
that we know what we're looking for, let's get rid of some
common "myths & misconceptions" surrounding
head lice:
 |
Having
head lice is a sign of poor hygiene! |
 |
Head lice
aren't that fussy. Clean, dirty, short, straight, curly
- all they want is blood! In fact, if you think about
it logically, it is probably easier for head lice to
move around in clean hair - without bits of dirt/dandruff
to climb over! |
| |
|
 |
You
can catch head lice from birds & other animals! |
 |
Human head lice are "host specific" - they
feed off the blood beneath the human scalp alone. |
| |
|
 |
Lice
can jump & fly from head to head! |
 |
Lice
have no wings (so they can't fly) & they can't jump,
either. They spread by "scurrying" from head
to head, or affected item to head (e.g. brushes, hair
clips, hats etc). |
| |
|
 |
Lice
can survive a long time off the head, waiting for the
next hapless "victim!" |
 |
A
well fed louse should only last up to 2 days off a human
host, depending on when it last had a meal. During this
time, it generally will not lay any eggs ("nits"). |
| |
|
 |
Head lice
live for months - that's why they're so hard to get
rid of! |
 |
Head lice
live for 4 - 5 weeks from nit (egg) to adult louse.
Females lay 4 -5 nits per day in the last two weeks
of their lives. |
