Head lice have been around for many thousands of years, and anyone can get head lice. As with any insect, they learn to adapt to their environment in order to survive. We are never going to be completely rid of them, but we can make managing them easier.
Head lice are small, wingless, blood sucking insects. Their colour varies from whitish-brown to reddish-brown and they can only survive on humans. Many lice do not cause an itch, so you have to look carefully to find them. Once isolated from the head, head lice die very quickly (usually within 24 hours).
Head lice are found on the hair itself and move to the scalp to feed. They have six legs which end in a claw and they rarely fall from the head. Louse eggs, also called nits, are laid within 1.5 cm of the scalp and are firmly attached to the hair. They resemble dandruff, but can’t be brushed off.
Head lice is spread is through direct hair to hair contact with another person or through hats and other surfaces which contain lice. Head lice cannot jump or fly but they can crawl and do hide.
What are Head Lice?
Pediculus Humanus Capitis commonly known as Head Lice are insects that feed on human blood. They do not have wings or knees and cannot jump or fly. Adult Lice grow to the size of a sesame seed and vary in colour from light to dark brown.
Who Can Get Head lice?
Anyone with hair can get head lice. Head Lice will attach to dirty or clean hair, they only need hair to hang onto and a blood supply to feed from.
Common Myths About Eggs
Viable (live) eggs are oval, dark in colour and can be very difficult to find. These eggs are located within 1cm of the scalp. They will hatch within 10 days.
Old eggs are also oval, range in colour from yellowy-white to light brown. These eggs shells are usually further down the hair shaft.
NO TREATMENT IS REQUIRED FOR OLD EGGS!
No treatment will kill a viable egg. Treatments are only effective after the lice have hatched.
