Best recipe for this we've tried. Takes about half a day for them to start hitting it, but once they do it happens in droves. We put it near the bananas on the counter & within about 2 days there were no more than 1 or 2 buzzing around. Thanks for sharing!
This was fine, however, I feel the funnel-type trap would be better for killing more fruit flies. Apple cider vinegar attracted the flies more then white vinegar.
