Wasp call outs are getting less as Winter approaches but there still active when its warm enough. On colder days the wasps are unable to fly out of the nest but they still try and work for the good of the nest. They come walking out of the nest and become trapped in the void where the nest was built. Often they will find a crack of light and squeeze through hoping to get outside. Often it will take them in to someones bedroom.
