I swear, we’ll have an empty pantry and fridge all weekend, but the moment we get groceries, you’ll see flies around the fruit bowl within a day.
Are they coming in on the fruit?
Are they waiting for the fruit to appear?

Not the flies but the eggs are on the fruit you bring home. Imagine how small fruit fly *eggs* are.
They can’t just spontaneously generate when fruit appears. The store always has some, they lay eggs on the produce, you bring it home and the fruit is carrying eggs that hatch every day. Doesn’t help that they reproduce super fast so even if a couple hatch in your kitchen you soon have a bunch.
