What do head lice look like?
Head lice are insects have six legs grayish completed by hooks. The louse is a bloodsucking insect, that he nourishes blood. The head louse feeds exclusively on human blood. Lice become red when they are taken their meal.
The louse is between 2 mm and 4 mm in adulthood. The head louse lives, as its not shown on the scalp of humans. His favorite residence is the neck and around the ears, the two locations of the cooler head. Mr. lice likes cool temperatures between 28 C and 32 C. A louse can live between 6-8 weeks.
After the legs of lice is a hook that allows it to cling to hair and resist brushing, the head movements and other shocks that could bring it down. But he happens to fall, but also to move from one head to another. That is how our children attrappent lice!
It is believed that lice are spread from one head to another by direct contact, face to face or hair dryer. Lice do not jump, but they walk very fast. Lice move by 23 cm per minute, which has long been led to believe they were able to jump.
Indirect transmission by clothing, pillowcases is low, the lice live only on the heads. The health professionals do not all agree, some believe that the risk of transmission of lice is also important in bedding, sofas by direct contat.
Recent Canadian studies on the subject tend to demonstrate that indirect transmission is almost zero (apart from the pool), but until more information is preferable to wash clothes and bedding components can cause infestation or reinfestation and treat hair accessories with an anti-lice.
The preferred means of transmission of lice is direct contact between children or between children and adults. The second means of transmission of lice is the pool, and yes lice too, know how to swim! The third means of transmission of lice is indirect contact through exchange of hats or helmets. For other indirect trade risks are much lower.
Except in cases of heavy infestation, it is a real headache whether our children have lice or not. Who does not scratch his head just thinking about? This is even more difficult than the lice are fast and can deceive the most watchful eye.
We think that lice twisted necessarily cause itching, itching in fact are the result of an allergic reaction to the louse injects saliva into the skin while feeding.
However nits do not go unnoticed, they form a kind of small ball attached to the hair can not fall when shaken hair.
It is therefore necessary to "listen" regularly the hair of our heads, and a child with nits can get lice, but not necessarily.
