Fruit Flies, Vinegar Flies—Drosophilidae spp.
Vinegar flies are so named because of their attraction to the sour odor of fermentation. They are also called fruit flies or pomace flies. They are nuisance pests in homes, restaurants, grocery stores and any location with fermenting or rotting vegetative matter, where they often build up large populations. They pose little threat to people, although they do transmit sour rot bacteria, which aids in the decay of exposed fruit.
