We haven't had fruit flies in a quantity that might qualify as an infestation, but once or twice they've reached annoying levels. We dealt with it successfully by simply isolating the fruit. What was ripe, we ate or processed into something that went into the fridge. What wasn't ripe went into closed containers of one kind or another, and we tried hard to remember to keep checking on them, to use before they went all the way to spoilage. And yes, we took out the trash promptly.

Cut off from their food supply, they don't last long.

Oh: and wash the fruit basket thoroughly to get rid of eggs.
