Fruit Flies in my Sweets

I started a couple of varieties of potatoes and sweet potatoes indoors. I have a ton of fruit flies. I have tried traps and vinegar in a bowl with a drop of soap to drown them. Nothing is working. Is there anything I can safely spray to knock down the population (of flies).

Have you tried spraying the leaves of the plants with a soap solution?

Here are some clever suggestions:

Craig said, "I've also put a dish of vinegar in the microwave with the door open. Turn the lights off and go to bed. In the AM shut the door and zapp them for a minute. DONE. Serve warm to chickens

Michael said, "Has any tried using a venus fly trap to fight this fruit fly battle?

Laura said, "I had the oddest experience, they didnt like the dry red wine i left them....shrug i went back to cider vinegar. I put it in a wine glass to keep evaporation down...any of the other methods seem right to me I will save a liquor bottle.

If they are living in a potted plant, they may be “fungus gnats” that are living off fungus in the damp soil, rather than actual fruit flies (drosophila).  I don’t have a magic solution, except that allowing the top layer of soil to dry out may reduce the population.
