New guidelines in the US are trying to reassure parents and teachers and make everyone treat the annoying lice a little easier. Too many myths have been associated with the tiny and itchy creatures, most of which are completely false. So are lice related to lack of cleanliness and how does hair length affect them?

What doesn’t kill, itches: According to a recently published guideline by the American Academy of Pediatrics it is “OK” to send children to school with lice. In the directive, it is stated that lice are “not a health hazard and are not a sign of poor hygiene”. On the other hand, sending a child home with lice in the middle of a school day can cause “significant stigma and psychological stress”.

Do lice spread diseases? Do they cause injury? Do they indicate poor hygiene? In a word: no. Here are some facts and myths that you should know especially when you meet an itchy and shy child at the end of the day.



  1. Who are you, wasp?

    Head lice are insects that spend their entire lives on human scalps and feed exclusively on blood 4-5 times a day. The lice may be found in all parts of the scalp, however the females prefer to lay their eggs in the nape of the neck and behind the ears. During their 4-week lifespan, female lice lay 50-150 eggs.

  2. Lice are not picky

    Lice do not pick heads and are found everywhere and in every area regardless of socioeconomic status. Lice also do not distinguish between people with different hair lengths, and the infection is not affected by frequent hair washing or brushing.

  3. Not a measure of hygiene

    The social stigma of lice. Lice are often associated with the idea of ​​not being clean, but that’s not true either. Lice are not a sign of poor hygiene – they need blood and don’t care if it’s from someone clean or dirty.

  4. Are lice dangerous?

    No. They are annoying and especially itchy more than anything else but they do not pose a health hazard and they do not spread any diseases.

  5. Lice cannot jump from head to head

    A head lice infestation is most often spread through direct contact with the hair of someone who has head lice. It is very unlikely to catch lice by sharing and transferring personal items (combs, brushes, hats, helmets). A study found that live lice were found on only 4% of the mattresses used by people with lice.

  6. Lice are specific to humans

    And they cannot pass between children and pets.

  7. Lice freeze when wet

    They cannot swim and this means that the best way to catch and remove lice is to keep the hair wet during the removal process. But only water will not kill lice as they can hold their breath for a long time.

  8. The itching is caused by their saliva and not by crawling

    Similar to mosquitoes, a louse bite causes an allergic reaction in the skin that leads to that uncomfortable itching. (However, the crawling itself can cause a tickling sensation).
