For Fruit Flies (Drosophila Fly), there is nothing better than ripening fruits in the house, which they eat and then lay eggs on top of. Not surprisingly, they are named after what they are attracted to, but they may also be found in areas where there is moist and decaying food, such as the garbage can. Therefore, it is important to dispose of and clean any produce or food that is fermenting or rotting and move all fruits and vegetables into the freezer until the infestation disappears.
