They come from other fruit flies. Fruit flies are little, and a single one is easy to miss. Imagine all the times you walk in and out of your home, and open this big 3’x7’ opening while you walk through it. PLENTY of time for one fly to sneak in while it was flying around your home sniffing it out. They’re basically “everywhere” to begin with.
That’s not even considering where the fruit was before it got home… but what I’m saying is even the fruit just materialized in your home, flies would find it before too long. Their life depends on it, you know? They’re exceedingly good at it.
