Fruit flies

[chancethegardener]

I have a serious problem with fruit flies. Some of the slightly cracked tomatoes are being attacked by fruit flies at the stage of ripening. Basically, when the flesh of the tomato is open to air (even a tiny hole), fruit flies come and lay eggs inside. In a few days, eggs become larvae and the scene is not only disgusting but also there is not a tomato left to eat. Has anybody experienced this before? What should I do?
