Lifecycle of Lice                                                                     THE FACTS OF LICE

    1. Head lice do not discriminate towards any socio-economic group and are not related to bad health or hygiene habits.

    2. Head lice do not transmit disease.

    3. Head lice feed only on human blood.

    4. Head lice do not come from animals or pets and cannot survive on a nonhuman host.

    5. Itching of the scalp is usually the first noticeable sign. The itching is caused by an allergic reaction to the saliva of the lice. 50% of people do not have this reaction!

    6. The time between when the egg is laid until the live insect dies is about 30-33 days. A female louse can lay up to 300 nits.

    7. There are approximately 5 female lice for every male louse.

    8. Head lice do not jump or fly, but they can crawl really fast!

    9. Humans cannot catch nits. They are eggs and do not travel.

    10. Transmission usually occurs through direct contact.

    11. Head Lice need to feed every 3-4 hours. Most will die within 24 hours of being removed from the host.

    12. Homes and schools do not get lice – people do!

    13. There are over 12 million reported cases of pediculosis human capitus (head lice infestation) each year.

    8. Report the infestation to school, camp, daycare, and close friends.
