The tiger mosquito, an exotic insect, come from Southeast Asia, settles more and more towards the north of the country, to the point that it is defined as a "major health risk" by a commission of inquiry of the National Assembly which met on the subject.

Small, silent, striped and who lives at night

In Montrouge, on the outskirts of Paris, Wilfried counts the insect bites on the skin of his eighteen-month-old daughter Emma. With his partner Solène, they know the culprit. "We see them immediately, they are striped", they explain to the microphone of Europe 1. These mosquitoes also have the particularity of living at night, of being silent and of having a rather small size. Five times smaller than its French cousin, the tiger mosquito measures less than 2 mm.

Up to 250 euros for insecticides

So in their small apartment in Montrouge, Wilfried installed many sophisticated devices supposed to hunt insects: ultrasound, ultraviolet ... which are not necessarily very effective. "I easily exceeded the 250 euros in that", laments Wilfried. Because the tiger mosquito is very resistant to insecticides.

Above all, it can pose significant health problems, warns Stéphane Gayet, infectious disease doctor at Strasbourg University Hospital. "This mosquito is feared because of the viruses it can transmit, such as chikungunya, dengue and zika", he explains at the microphone of Europe 1.
