Vinegar flies is the collective common name for the broader genus Drosophila, which includes dozens of species beyond the common fruit fly (D. melanogaster). The name 'vinegar fly' reflects their strong attraction to acetic acid — the compound that gives vinegar its characteristic smell and that is produced during fermentation. In Arizona, vinegar flies are particularly problematic in wineries, craft breweries, kombucha producers, and any facility that handles fermented products. They are also common in homes around wine racks, beer storage, vinegar bottles, and fermentation crocks. Like fruit flies, they breed in small amounts of fermenting organic matter and can develop from egg to adult in under two weeks. Several Drosophila species are also attracted to decaying mushrooms, fermenting plant sap, and rotting vegetables. Their small size allows them to enter through standard window screens.
