C.K.
I had the same issue with fruit flies and also tried the cider vinegar. I also put a glass of red wine right next to it and after a few days I had the same amount of fruit fly bodies in both. After that I put all of the fruit in the fridge and started cutting off the very top of the bananas(one of the other "Mamas" wrote that the banana tops are where they all come from). It has gotten remarkably better but I am not convinced that anything gets rid of them completely. Good luck!
