France in Focus

Not sure of the difference, but our friends are having a big issue with flies.

They're prevalent in a few rooms but not the whole house.

They're using fly spray on their walls and windows, which kills them but within minutes they're back.

They are just usual smallish black houseflies, they buzz.

Don't know if they are cluster or not.

Any tips or suggestions for getting rid of them?

Its been a bad year for flies and mozzies, when its hot windows open but shutters closed, have used a lot of sprays this year.

I think cluster flies wings crossover each other when they're closed unlike houseflies which stay separated, I'm afraid I don't have any tips for getting rid of them though.
