As it says. I am petrified of wasps and have used citronella candles and netting in the past. Last summer DP refused to allow netting up and we had so many wasps at one point we both seriously thought there could be a nest in the roof. They come in the kitchen, living room, bathroom and bedroom. I've found them in the wardrobe before, which is quite unnerving.
It's a rented flat and I like having the windows open. I don't want to spend another summer with them closed. Is there a spray or treatment I could put on the windows to stop them coming in please?
