I haven't tried this for flies. Though, one time was renting an apartment that turned out to be termite infested and they had just happened to start
leaking out of the wall. The vacuum worked pretty well, or it would have been spaying them down, waiting for them to perish then clean up the mess
If you cut a plastic 2 liter bottle in half, have the top half turned to the inside-with the cap off, of course-, then have something sweet-preferably
water, soda, other,- appealing to flies on the bottom-, they will flies will be caught(for those who want to let them go outside instead) and or
drown. It works alright with them, better with smaller fruit flies and knats and sometimes with wasps and hornets.
