Welp,
If you have them in your compost then, you mostly have a pile of garbage rather than compost. you need to turn the compost when it cools down to about 90 degrees. When it cools it's because it's used up the oxygen and needs to be stirred up so the supply is replenished. If the problem persists, you might need to add some dryer material like leaves or straw to the mix. Fruit flies can'tlive in a hot pile with moderate moisture content.
In the house, I find just getting the source of food out of the house for a few days does the trick. Adding diatomaceous earth to the compost inside and out helps too.
