They measure just a few millimeters, with a limited life expectancy of 30 days. However, lice often play spoilers in your children's hair. Focus on these invasive pests.

What is the morphology of the louse?

  • Of the class of insects, the louse has six claw legs but, unlike his peers, it lacks wings. He does not fly, nor does he jump like the flea, but clings with all his strength to the hair.
  • Once installed, he uses his trunk to prick the scalp and feed on blood. His chest and abdomen are segmented. Each segment carries a pair of breathing ports, which carry the oxygen necessary for its survival.

How does the louse live?

  • Lice live exclusively around the scalp of human beings. Madam does not know how to brood and lays her eggs - the nits - caramel color shining at the root of the hair. With heat and humidity, they find ideal conditions for growth. Eight days later, a baby is born.
  • The slow becomes empty takes a whitish hue. It looks like a film, with the difference that it does not fall! For its part, the baby can eat avidly scalp blood two to four times a day. He becomes an adult in two weeks, mates, and, for the female, lays eggs: the infernal circle is closed.

Are there ragweeds?

  • Without being able to give a scientific explanation, it is found, in fact, that some children have more lice than others. Girls are three times more likely to have these parasites than boys. This may be due to their longer hair, their games that call for closer contact or the loan of objects (comb, hair brush). Another observation: each individual emits his own "pheromones", odors that can be more or less attractive for lice.
