Fruit flies live only for a few days so the population should die out by itself, especially if you plug your drains overnight and cover fresh fruit or other foods you keep on the counter overnight. If the problem is with fungus gnats (tiny flying insects) rather than fruit flies, there is hope in controlling the population.

These pests reed and breed in moist potting soil and you can break the breeding cycle by allowing the surface of the soil to dry out. If you have plants that need moist soil simply place a quick draining and fast drying layer of gravel or sand on top of the potting soil. You have to be a little patient with this method because you have to wait through the next generation's maturation before they are gone for good. In other words, once the generation now already in the soil become adults and die off without being able to reproduce, there should be no more gnats. Another method is to use a product called Gnatrol as a soil drench, another is to use an insecticidal soap as a soil drench. Of course, always follow the label instructions carefully. Another way to control fungus gnats is with yellow sticky traps. You can make them yourself. Paint a piece of wood or cardboard yellow and cover with vegetable oil or anything sticky and clear. Suspend above the plants. The gnats are attracted to the color yellow. You should be able to trap out most of the trouble makers! Good luck with your eradication project!
