My third-floor apartment has a balcony, the door to which I can never open because there's always a gang of flies hanging about threateningly outside the door, waiting for their opportunity to storm my house.
I've taken a look around the balcony and there's nothing on it or over it that would attract them - no plants, food, rubbish, nothing. There's an overhanging roof but that's it. Anyway, I don't particularly want to kill them but every time I open the door loads of them fly in and they're pretty disgusting. They look like ordinary house flies. Does anyone have any advice on how to keep them away from my balcony or at least out of the apartment? I've tried spraying the door with fly spray but it's not working.
