Spray elsewhere in the city? “A false good solution”
While many testimonies report a strong presence of the Tigre mosquito in Châtellerault, this conclusion may surprise. Response from the Health Authority: “The tiger mosquito has actually been present in Châtellerault for a few years, but that does not mean that the whole city is infested. The area that was analyzed (150 m around the infection fireplace, in the center of Châteauneuf) is very urbanized, with few stagnant water points, which leaves little room for the mosquito to develop. »»

It takes “health interest”
“It wouldn’t solve the problemsays the institution responsible for organizing health policy in the region. On the one hand, such an operation only kills adults, not eggs or larvae. In other words, the stop of nuisance would be short -lived. Also, it is done only when there is a sanitary interest, to avoid, after the revelation of an imported case, to have indigenous cases. On the other hand, in the longer term, this gradually favored resistance to mosquitoes, which would harm the wrestling operations which, it would have a health interest. »»
