2 What are head lice (Pediculus Humanus Capitis)?

3 Head lice are small parasitic insects
Head lice are small parasitic insects. Head lice only live on human scalps. They feed on human blood and without it they can’t survive. They feed several times during a 24 hour period.

4 Head lice can only live for 24 hours off the human head away from its meal of human blood!

5 Lice vocabulary Louse – a single adult Nits – lice eggs
Lice – more than one louse

6 What do Head Lice look like?
Adult Head Lice are 2 – 3mm in length (about the size of a sesame seed) They are tan or grey-white and have six legs, each with a claw

7 Where do head lice come from?

8 Head lice do not come out of the air or from the ground
Head lice do not come out of the air or from the ground. They are human parasites and have probably been here since the beginning of time. Desiccated (dried up) head lice and their eggs (nits) have been found on the hair and scalps of Egyptian mummies.

9 How are head lice spread?

10 Head lice are spread from one person to another by close head-to-head contact.

11 There is also the possibility of spreading head lice from backs of chairs, sofas, car seats, mattresses, pillows or similar items.

12 Lice can also be spread through sharing hats, towels, combs, brushes, helmets, hair bows, etc.

14 Can I catch head lice in a pool?
Swimming with someone who has lice carries no greater risk of transmission than any other activity. When lice are in water, they remain firmly locked onto the hair – literally hanging on for dear life. This is how they survive regular shampooing and swimming

15 Can head lice jump or fly?

16 ~Head lice do not have hind legs to hop or jump
~Head lice do not have hind legs to hop or jump. ~They also do not have wings and cannot fly.

17 Important Head Lice Facts:
Because Head Lice cannot jump or fly, they crawl from one person to another using their claws to grab onto hair Head lice are NOT spread from dogs, cats or other pets

18 Another important Head Lice fact!
Personal hygiene and the cleanliness of your home or school DO NOT have anything to do with whether you get lice

19 Who’s most at risk for Head Lice?
Kids in daycare Preschool and Elementary school children Family members of children who have lice Girls are more likely than boys to get lice (more likely to share hair items, close head-to-head contact and usually have longer hair)

20 Lice have a life span of around 30 days

22 What are the signs and symptoms of head lice? You may feel:
A tickling feeling of something moving in the hair (lice crawling) Itching (caused by an allergic reaction to the bites of lice feeding off the blood in the scalp) much like mosquito bites Sores on the scalp (cause by scratching)

23 Head lice normally prefer the following areas of the head:
Over the ears and the nape of the neck (the warmest areas of the scalp)

24 If you think you have head lice:
If you are at school, tell your teacher The School Nurse will check your head for head lice and nits If you are at home, tell an adult and notify your school if lice are found

25 School Nurse checking for Head Lice and Nits
1)The School Nurse will look for live head lice and fresh nits to confirm an active infestation. 2)If possible, a live louse will be placed on a piece of tape and placed under the microscope as confirmation of head lice for the student’s parent/guardian.

26 If I have head lice, what do I do?
Don’t Panic The School Nurse will call the parent/guardian to pick student up for Head Lice Treatment If parent/guardian has any questions, School Nurse can provide information for Head Lice Treatment

27 What can be used to treat lice and nits?
Wayne County School Health recommends using Olive Oil 1. Apply generous amount of Olive oil to scalp and hair massaging well. 2. Cover head with shower cap and leave the oil on at least 8 hrs. 3. After 8 hours with the oil still on the head, comb with a regular comb to remove dead lice 4. Remove nits from hair (‘Nit Picking’) 5. Shampoo hair 6. Repeat Oil and “Nit Picking” treatment every 4 days for 3 weeks.

28 No Nits!!!

29 Why the “No Nit” Policy? Nits are the eggs of head lice. Nits are oval-shaped eggs that are glued to the hair shaft close to the scalp (within ¼” of the scalp). Fresh nits appear dark. You cannot “catch nits”. Nits must be laid by live lice. Once laid, it takes 7-10 days for a nit to hatch, and another 7-10 days for the female to mature and begin laying her own eggs. Thus the “No Nit” policy. Any surviving nits will hatch into crawling lice within days, generating a cycle of reinfestation. Removing all nits insures complete treatment!

30 If any nits are left in the hair…
Don’t take the risk!

31 If olive oil is not used, use a pesticide-free treatment
Non-toxic, safe, odorless and hypoallergenic Simply follow directions in package

37 Before returning to class:
Your school nurse must re-check your head to make sure all lice and nits are gone If your head has no lice or nits, you may return to class

38 What can I do to prevent Head Lice?
