It is recognized by its body and legs striped with black and white, and by its size larger than the common mosquito.
The tiger mosquito is also less swift and noisy than its cousin, and it bites only during the day. Or rather it, because only the females bite, for reproductive purposes.
The tiger mosquito is also and above all a vector of the dengue, chikungunya and Zika viruses, and its expansion on French soil increases from year to year.
Thus, in 2019, 51 departments were placed in “red vigilance”, with a tiger mosquito “implanted and active”.
They are now 58, and 9 others are on “orange alert”: this means that “the mosquito has been punctually intercepted there in the last 5 years”.
Another important development: if previously, the cases of dengue, chikungunya and Zika were “imported” (the symptoms were declared on the return from a trip), the situation changed last fall: three indigenous cases of Zika were detected in the Var, and around ten indigenous cases of dengue fever have been identified in the Rhône-Alpes region.
Loose clothes and empty cups
To protect yourself from the tiger mosquito and prevent its spread, it is recommended to destroy or dry up the stagnant water reserves inside or outside the home: gutters, flowerpot cups, particularly prized by females for lay their eggs.
To avoid getting bitten, you can wear loose, long clothes and use mosquito repellents: electric diffusers inside the houses, and coils outside.
The use of repellents is recommended, with caution, in pregnant women and children under 12 years of age. For babies under two months, it is recommended not to use any repellents and to favor the use of impregnated mosquito nets.
