Il is only 5mm, but its spurious performance is inversely proportional to its size. The tiger mosquito has been spreading in the Dordogne for ten years – it has been detected in 52 communes – and spoils the hot evenings.

“In the summer of 2020 I didn’t go out anymore. I couldn’t eat outside once,” plague Martine Doyen, elected community officials in Boulazac-Isle-Manoire.
