It's also cheaper than using my high quality apple cider vinegar which I love and really don't wish to waste on fruit flies. 3. Third, I didn't have to. Flies just can't resist the sweet aroma of decaying fruit. So if you have ripe or overripe fruit you can place it in the jar with the apple cider vinegar. Apple Cider Vinegar is truly a heaven send for attracting fruit flies. I love to dip tea bags into essential oil blends and hang around the home.
