For some reason at our house we have a fruit fly problem. They're gone now because we never leave produce on the counter, opened foods etc anymore. But it's a pain because then I can no longer ripen fruits!

How do you get rid of fruit flies?

I have tried apple cider vinegar, balsamic vinegar and the latter did nothing. The apple cider worked for the first few days. The pre-purchased fruit fly traps are just filled with apple cider.
