Hi Folks. I live and work in the south of France and cicadas are part of the soundscape all summer here. On stage, one of the better way to get rid of their sound is to have an assistant with a hose pipe. Between each take, he waters the tree from which cicadas are singing (in french we say they sing). As it cools down the temperature, cicadas stop singing for a while (they don't make noise when temparture is below 25° C). As a re-recording mixer, I'd rather use a post-production tool such as Izotope RX.
