double sided sticky trap sheets around a container of apple cider vinegar. in the same amount of time it took to catch these, premade traps have caught 2-3 flies each

edit: For people saying those are too big to be fruit flies, I found a regular fly (this one is actually kind of small for a fly) in my windowsill and stuck it next to the ones I caught

the sticky traps are 7.5x10cm. Also that’s standard sized scotch tape holding them in place.

are they some other kind of fly or gnat? Idk, but they’re much smaller than house flies. I took the picture very close and it’s a small ramekin
