About head lice
x Head lice vary in size according to their age. From the size of a printed full stop.... ....to the size of a
sesame seed Head lice can be difficult to spot because they can match their colour to that of the
environment.
x Lice live close to the scalp where they feed on blood and this can cause the scalp to itch.
x Head lice cannot jump, fly or swim and can only be acquired by direct head to head contact. This is why
lice are commonly found on the heads of children and those in close contact with children and why it
important to check the heads of all the family members when head lice are found.
x Head lice only live on humans and have no preference for clean or dirty hair.
x The female louse will lay between 3 and 5 eggs per day and these hatch after 7 days. This is why it is
important to repeat this treatment after 7 days to ensure that any lice which have hatched after the first
treatment are killed.
x Once the louse has hatched, the empty case (known as a nit) will remain glued to the hair shaft. Nits are
completely harmless and can be removed with the fingers or a fine- toothed comb.
