How do I get rid of fruit flies?

[Dunkel]

Take a shallow white bowl and put some water, a couple drops of dishwashing liquid, and a little vinegar in it. They will die in there quickly. Replace this mixture everyday. Make up a few of them for better results. Put one near your TV and lamps/lights. They are attracted to the light and electromagnetic field (I heard it on a bug killing show). No matter what we do we get fruit flies every summer. I hate them.
