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. His colleague Janique Plu agrees: “We find them in densely populated areas. We have received complaints from local residents. They kept asking us what we were up to. We were even asked to sulfate…”
This last request alone illustrates the ignorance of this exotic species that thrives in urban or suburban habitats.

His Escoire alter ego, David Barreau, is recovering: ‘Now we can tell people it’s not true. The discussion begins between the two men. They identify a potential site of distribution: cemeteries. “I often see elderly people filling the cups under the flower pots, especially because of the high temperatures.
