Fruit flies

So we were wondering last night...Where do fruit flies come from? It seems that they suddenly appear, within seconds, of having open fruit. Last night it was pineapple. No fruit flies in sight whilst eating dinner, yet 3 seconds after opening the top of the pineapple, fruit flies abounded. Where were they? Are they just sitting on the wall, under the table, waiting for fruit-hoping today will be the day? I'm stumped.

What about regular flies too? How do they suddenly appear on the 4th floor of a building with windows that don't open... do they take the elevator or the stairs?
