i've seen videos of that weird rotating disk trap but i don't know how good it is
in theory you can put something irresistible like meat in it and it would decimate all the flies
but i find the best way is by luring them via light and windows
i have some screen windows and i find that if i just leave them open by a couple inches, flies will flock to the window to try and get outside but they will instead get inside the are between the glass and the screen and be unable to get back out (but they will eventually given time), so you can trap a lot in there in an hour or two and then close it and they'll die in a day or two depending on the weather, or you can spray them with soapy water from outside and kill them instantly (you will need to rinse the window after or else it;ll look terrible)
but again to the light thing; outside of food, they are very much attracted to bright things, so for example you can set up something like a milk jug with a big bright white funnel on it, with some mixture of different things (i think cooked meat is the most desirable thing to flies) and they'll gladly and easily fly into what appears to be a huge target to them, and they'll be unable to get back out through the small funnel hole (you have a better chance if the bottom side is black or something, they have a hard time seeing dark things)
i haven't tried this method myself, but it should work
i do know they love flying into my room constantly because it has a bright white door that guides them in if it's open
for a more passive approach you can simply dedicate a room in your house, ideally with a window, and keep the light on all day and all night
at night, flies will seek light much like moths do, and if you leave fly tape in that room, eventually they'll fly into that, and the more flies on fly tape, the more are attracted to it
you can do the window trick here too, but mostly they're just attracted to windows, and i believe they can feel the breeze
