I hate flies too. Im not an expert but feel like airing my droning voice anyway on the subject.
Firstly I on a property in Garrucha and so far the flies seem put off by the constant breeze that runs up the hill there. Thats no good for you except I think its a hint as to what flies do not like- wind!
You can only do all the things that are conventional. Put nets or meshes over your windows, use shop proprietary scents that are supposed to deter them. Try and establish what time of the day theyre active, and if you have one- turn your air con on to make it as cold as possible. Buy those electrocuting ulta violet lights and hang them outside the house (They get attracted to the light so you don't really want them in the home). Light a barbeque and make it smoke slowly. Light insence sticks. (Don't know how but (encourage birds to fly and live around your house (They eat the things) , any standing water nearby that you can fill in with soil to reduce their spawning grounds. Even drop a bit of oil onto open water to suffocate them. Make a sport out of them by buying those electrocuting fly swats. Its so much more satisfying to hear them pop and they get killed. Sometimes the oils they sell there in general stores can deter them if you drop some at doors and windows.
