So what is the secret in Murcia region to keeping the flies at bay? We have been spraying around front and at back doors, tried that fly trap from Chinese Bazaar that entices them into a cone and slow death only to smell to high heavens, to dishes of apple cider vinegar, pretty much to no avail. Our dog is going ballistic trying to catch and swallow every one, so we are worried what this will do to him as well. We bought one of those ultraviolet lights to plug in but they seem useless unless it's dark. We are actually more worried about the dog right now that our annoyance with them.
