There are no flies in my house, but if I leave a piece of fruit out too long, they show up. Even if it’s far away from any doors or windows, they’ll be there. So, where do they come from?

There’s fruit fly eggs on and in the fruit you bring from the store. If you don’t eat the fruit soon enough, the eggs hatch at your house. Some can flies come in your windows and doors too, but for fruit flies that’s not the main source.
They’re on the fruit.
