We are in the plain of crau, the sheep environments, so the flies are well arise, even in December. As for mosquitoes, we are very close to the Camargue! I will continue my experimentation, but for now, we made taunted by a mosquito that has just passed through the racket, without flinching and we had put into service racket with batteries. We need to see this on the flies, which are a bit ensuquée in the area!
