Hi all moved to a lovely new house with 3 flours which we love, only problem we have lots of windows and a sunny aspect. However are getting flies in the house more on the third floor. We are opposite a field lovely view wondering if this is part of the problem. I love open windows really believe in them, so finding it distressing. Never had this problem before and am very clean and organised.. Any advice for products that may actually work and be discreet. its not all the time. Thank you love this site for info, Mums always have knowledge.
