-Lice do not jump or fly, they have no wings (their short stumpy legs render them incapable of jumping, or even walking efficiently on flat surfaces)
-Lice cannot live off of the human body for more than 48 hours.
-Poor hygiene is NOT a factor in contracting lice. They even prefer clean hair.
-Dogs and cats cannot get or transmit lice. (lice only like human blood)
-Traditional chemical lice treatments are NOT 100% effective at killing live head lice and they are not effective at all in killing and removing nits (lice eggs).
-If you have not removed ALL the nits from an infected head it is very likely that you will become reinfested. By the time a head lice infestation is identified, you can usually assume that the infestation is already about 2 weeks old.

Exodus 8:15-17 (NKJV)
And the LORD said to Moses, Say to Aaron [Moses’ brother], “Stretch out your staff, and smite the dust of the land, that it may become lice throughout all the land of Egypt.”
And they did so; and Aaron stretched out his hand with his staff, and smote the dust of the earth, and it became lice in man, and in beast; all the dust of the land became lice throughout all the land of Egypt.
IMAGINE!
After seeing your child’s head lice, this is a pretty gross picture painted in Exodus!
WHAT ARE HEAD LICE?
Pediculus Humanus Capitis is commonly known as head lice (and to some of us – “cooties”). They are parasitic insects that live on the human head and survive by sucking the blood of their host. Humans and Chimpanzees are the only known host of this specific parasite. Lice eggs are called nits, and they're laid by the adult female louse. The nits are attached to the base of the hair shaft by very strong cement (the glue was previously thought to be chitin-based, but more recent studies have shown it to be made of proteins similar to hair keratin). They are located close to the scalp because they require body heat for incubation.
The average life cycle of the louse is 3-4 weeks. Nits take 7-10 days to hatch. The hatched nymph takes 7 days to mature into egg laying adults. The female adults lay an average of 6 nits per day. A generation lasts for about one month.
There are 6-12 million cases of head lice in the United States each year, and most of those cases are young children. Girls are two to four times more frequently infested than boys. Lice are very contagious and are easily spread from head to head contact, as well as sharing brushes, combs, headphones, cell phone, hats and other personal items.
The most commonly reported symptom of lice infestation is itching. However, it's important to note that many cases display no symptoms of itching at all. Likewise many people have itchy scalps all the time, but never have lice. Lice infestation is rarely dangerous; at its worst secondary infections can develop from excessive scratching of the scalp and breaking the skin. By the time you find them crawling, it has already been 2 weeks.
This is no game!
Most schools and daycare centers have adopted the "no nit" policy recommended by the National Pediculosis Association. This policy means children cannot attend school if nits/ lice are found in their hair. None of the insecticide treatments mentioned above will remove nits from the head. There is no safe solvent for the glue that the female louse uses to attach her eggs to the hair even though there are products that make such claims. Combing is the only sure way to remove nits from hair.
Because children spend so much time at school or day care, these facilities are sometimes accused of being the places where head lice get transmitted from child to child. Head-to-head contact is the most likely way lice are transmitted from one child to another.

All stages of the louse are blood-feeders and they bite the skin four to five times daily to feed. "To feed, the louse bites through the skin and injects saliva which prevents blood from clotting; it then sucks blood into its digestive tract. Bloodsucking may continue for a long period if the louse is not disturbed. While feeding, lice may excrete dark red feces onto the skin.
The following poem was written by the Scottish poet, Robert Burns, in the late 1700's. Should you want to focus on it, you will find it is a humorous acknowledgement of the wealthy women sitting in their own church pews with their finery on and their noses in the air. The person sitting behind one of these women finds delight in seeing these critters crawling on her hair, bonnet, lace and furs. The last stanza ends with the funny and famous line...
"O, wad some Power the giftie gie us
To see oursels as others see us!"
To a Louse
(ON SEEING ONE ON A LADY'S BONNET AT CHURCH)
Ha! whare ye gaun, ye crowlin ferlie!
Your impudence protects you sairly:
I canna say but ye strunt rarely
Owre gauze and lace;
Tho' faith, I fear ye dine but sparely
On sic a place.
Ye ugly, creepin, blastit wonner,
Detested, shunned by saunt an' sinner,
How daur ye set your fit upon her,
Sae fine a lady!
Gae somewhere else and seek your dinner,
On some poor body.
Swith, in some beggar's haffet squattle;
There ye may creep, and sprawl, and sprattle
Wi' ither kindred, jumpin cattle,
In shoals and nations;
Whare horn or bane ne'er daur unsettle
Your thick plantations.
Now haud ye there, ye're out o' sight,
Below the fatt'rels, snug an' tight;
Na faith ye yet! ye'll no be right
Till ye've got on it,
The vera tapmost, towering height
O' Miss's bonnet.
My sooth! right bauld ye set your nose out,
As plump an' grey as onie grozet:
O for some rank, mercurial rozet,
Or fell, red smeddum,
I'd gie ye sic a hearty dose o't,
Wad dress your droddum!
I wad na been surprised to spy
You on an auld wife's flainen toy;
Or aiblins some bit duddie boy,
On's wyliecoat;
But Miss's fine Lunardi!—fie!
How daur ye do't?
O Jenny, dinna toss your head,
An' set your beauties a' abread!
Ye little ken what cursed speed
The blastie's makin!
Thae winks and finger-ends, I dread,
Are notice takin!
O, wad some Power the giftie gie us
To see oursels as others see us!
It wad frae monie a blunder free us
An' foolish notion:
What airs in dress an' gait wad lea'e us,
And ev'n Devotion!
