The
Life Cycle, Symptoms, and Spread of Head Lice
Head lice are parasitic insects found most commonly behind the
ears and near the neckline at the back of the neck. The medical term
for head lice infestation is Pediculus humanus capitis. There are
6 12 millions cases of head lice in the United States every

Head
Lice
Head lice are blood sucking parasites. They are approximately
the size of a sesame seed, 1-2 mm. They do not have wings and, therefore,
cannot fly. They also do not jump. They do, however, move quickly.
The eggs of the louse, which are called "nits", are teardrop
shaped and approximately half the size of the adult louse. The nits
are attached to the hair shaft with a waterproof, cement-like substance
from the adult female. Thus, nits cannot be simply washed or brushed
out of the hair...head lice?

Head
lice alert - includes related information
Known since ancient times, the head louse - Pediculus capitis
- is a tiny, six-legged, wingless, greyish insect that infests the
scalp and head hair. Lice feed on blood, breeding and laying their
eggs on the human scalp. Although annoying, head lice are not a
health threat and do not carry diseases (although other forms can
transmit disease). Head lice do not jump or fly but get from person
to person by scuttling from the hairs of one head to those of another.
Having lice does not mean someone is dirty, neglected or poor. Head
lice are just as likely to live on rich as on poor people, and they
are even said to prefer clean to dirty hair!...
