What are head lice and what do they look like?

  • Head lice are tiny, blood-sucking insects. They can't fly or hop as they have no wings or strong legs but they can crawl fast!
  • Baby lice are only about the size of a full-stop, are almost see-through and they're very tricky to spot. Adult head lice are 2-4 mm long red-brown to grayish white and camouflage to blend in.
  • Nits (louse eggs) are only about the size of a sesame seed and are glued at an angle to a strand of hair.
  • To remove a nit you'll have to slide it all the way down a strand of hair with your fingernails.
  • Nits take 7-10 days to hatch, are yellowy coffee coloured ovals and are usually near the crown of the head, around the ears or the nape of the neck.

Who gets head lice?

  • Anyone. Lice are not fussy about your age, sex or hygiene. Lice are transmitted mostly through head to head contact so are more common in young, school-aged children. Its easy to get head lice but hard to get rid of them so if your child has nits, you'll need to have your entire family checked.

​How do I know if my child has nits?

Common symptoms include:

  • Itchy scalp
  • A tickling of something moving on their scalp or through their hair
  • Red marks caused by excessive scratching or a red rash on the back of the neck.


Is it “nits” or lice” or “Louse”?

In common use these terms are often interchangeable. Strictly speaking though:

  • ​Lice is the plural of louse, the insect stage of the life cycle
  • ​Nits are unhatched head lice eggs.


​Where should I look for Lice?

  • Start near the scalp, around the ears and near the nape of the neck, then check the rest of the scalp. Not sure its a nit? Blow on it and if it stays attached to the hair it could be a nit. If you find eggs you probably have lice bugs too because they don’t lay themselves.

Can I wash out head lice?

  • No, lice can hold their breath for up to 2 hours. They lock their claws onto the hair and hang on and the eggs are glued to the hair. Lice can shut down their nervous system too, and can remain submerged, safe and sound, even in stuff designed to kill them. In lab tests, lice played dead for two long hours!


Does having head lice mean I am dirty?

  • Getting head lice does not mean you are unclean, they actually prefer clean hair. Dirty hair won’t prevent them from laying eggs in your hair though so don’t try that.

Will a haircut help?

  • Cutting your hair won’t get rid of lice or stop you from catching them. However it does help to have shorter hair when you’re removing them yourself - long or thick hair can be hard work.
  • Remember long hair does dangle more so you may want it tied back especially when at school.


My head doesn't itch, can I still have lice?

  • Yes, itching is caused by an allergic reaction to lice saliva. Only half of those affected develop itching.
  • When the bugs are removed the irritation may take a little time to go away.

Are head lice dangerous?

  • No, they are just very annoying!
