      Any fruit can have fruit fly eggs. They’re attracted to overripe fruit, and even though what you bought was fresh, it might have been on the dock next to something turning into wine. I avoid fresh fruit from Walmart because they seem to be particularly bad, but flies are in high end groceries and farmers markets too. Every grocery store is in a constant, if discrete war with the creatures.

      They can be quite annoying and breed famously quickly. A friend went on vacation for a week with some banana peels or something in the trash and came home to a swarm of thousands.

      Perhaps you live in a cool climate? It’s sub-tropical where I am and the flies usually disappear with the fall weather.

        I do live in a cool climate, though it’s not as though it stays cold all year. We still have hot summers, but even then I have never noticed this and I buy produce pretty often. Didn’t even know this sort of thing could occur for not-overripe fruit.
