The insect is a vector of disease.
It is the Regional Health Agency which announces it: after Indre or Cher, the tiger mosquito is continuing its expansion in Center-Val de Loire and settling down permanently in Indre-et-Loire.
"The analysis of the reports of individuals and the surveys of nesting traps made it possible to detect the presence of the tiger mosquito in two towns of Tours metropolis: in Tours, around Place Coty and in Joué-lès-Tours, around the cemetery de la Rabière. The extent of the colonized areas makes it impossible to consider insecticide treatment " write the health authorities.
In France, 58 departments are now officially colonized by the tiger mosquito.
"The tiger mosquito can transmit certain viruses (Dengue, Chikungunya, Zika) if it bites a recently infected person while traveling in the tropics" again indicates the Regional Health Agency. If the peak season for bites is in summer, the insect is "Active" until November and especially its eggs resist the cold of winter … so it reappears like a flower during the spring, and can therefore quietly extend its influence.
So how do you slow down its expansion?
1 – "Before winter, turn off the water to the mosquito to prevent its proliferation and protect yourself" ARS indicates that " each female tiger mosquito lays about 200 eggs. In contact with water (even in small quantities: the equivalent of a plastic bottle cap is enough to lay eggs), the eggs give birth to larvae. This is the time to act, removing all the standing water! "
2 – Cover the water tanks: water cans, cisterns, basins with a veil or a simple cloth as well as end-of-life swimming pools. Eliminate places where water can stagnate, both indoors and outdoors: flowerpot cups, used tires, bulky items, children's games. Also remember to maintain graves in cemeteries, places conducive to the development of mosquitoes. Check the correct flow of rainwater from the gutters.
3 – Learn to recognize the tiger mosquito to signal its presence. It is very small (about 5 mm, wings and proboscis included), it has black and white stripes (no yellow), on the body and the legs, it lives and stings during the day, its sting is painful.
