How to get rid of nits and head lice

To understand the best way to eradicate head lice and nits, it helps to know a bit more about them.

Information on nits and nit infestations

  • The scientific name for a head louse is ‘pediculus humanus capitis’.
  • A head louse infestation is sometimes referred to as ‘pediculosis’.
  • Head lice are tiny (2-4mm long) wingless brown hair parasites that live in the hair and on the head of humans, feeding on blood that they suck from the scalp.
  • Head lice are highly contagious and are easily spread through head-to-head contact.
  • Head lice cannot survive for long away from a host as they need regular blood meals.
  • The head louse lifecycle lasts approximately 30 days, during which the louse passes through three stages:
    • Eggs: Often called nits

      An adult female louse will lay approximately six or seven grey head lice eggs (nits) a day which she cements firmly to the base of the hair shaft with a very strong glue-like substance. They live close to your head where it is warm.
    • Nymphs:
      After seven days, an immature hair louse (nymph) will emerge from the egg (nit); the empty nit remains glued in position.
    • Adult lice:

      After shedding their skin (moulting) three times, head lice nymphs become sexually mature adults; this normally takes 10 to 14 days. Within a day of becoming adult hair lice, male and female lice will start to reproduce – and numbers can grow at an alarming rate if left untreated. Very soon hundreds of lice can be living in your hair laying nits every day.
