Although I consider myself a person of science and thereby don't believe in spontaneous generation, I'd say fruit flies are the perfect example of it.

In my experience, if you get ride of the source of fruit fly food or whatever's attracting them, they'll thin out/disappear in a few days. You might even try spraying them with a bug killing spray but since it's your kitchen be careful so you don't poison yourself!

I don't know what could be causing it, since you've listed the most common things I would have guessed. Does it seem like they're all sitting in one place and then swarm around when you walk in? I would investigate the place they sit. there must be something there.

Also, standing water in a sink, especially with food remains, can attract them.

try the raid flying insect spray also a god sent during the fly season. Just mist the enitiry of your kitchen or where ever else they might be close the door make sure all windows are shut and leave it be for 10 min or so. If you have a big kitchen like me it could tae allot of mist the fruit flys just do not die as easy as regular flys. I hope this helps

This seemed somewhat helpful I've learned a lot about fruit flies in mere minutes :)

Good luck!
