I absolutely hate fruit flies! This trap is very easy to make and works really well. I always have this trap set up on the counter, so an infestation never has a chance to take hold. :)
Approximate Time: 5 minutes
NOTE: I change out my mixture about every 2 weeks, more often if I am catching a lot of fruit flies.
Wait about 15 minutes or so and then quickly shut the bag trapping the flies inside. Take the bag outside and let them loose. I had to do this three times as they are fast little buggers.

I placed a large bowl of cider vinegar with a few drops of liquid detergent on a large dinner plate. I used the scraps of a fresh tomato that I had cut and placed around the bowl on the plate. I covered this loosely with wax paper with some slits on the top to allow the flies to enter easily. I let this sit with the microwave door open for about an hour.
After that hour, there were a large amount of flies on the bowl and plate. I quickly closed the microwave door and then turned in on high for one minute. The flies were zapped dead when I opened the door. I wiped it out and repeated one more time; keeping the oven door open again for an hour. This killed the majority of the fruit flies in the kitchen. A few were flying around the kitchen, but I was able to rid of them with the fly swatter. So far, the fruit flies are gone.
Be sure to use dishes/containers that are microwave proof. Since you will be cooking in the microwave, use enough cider in the bowl so it doesn't cook off. Also, use large enough pieces of fruit/produce that will not burn while cooking. Our microwave is 1100 watts so the time may vary. I used wax paper to keep any of the food from splattering, but put slits in it to allow the flies to enter. I had a concern because there are small holes inside of the microwave; I thought maybe the flies would escape, but I watched while the microwave was running and the flies did not go into any of them.
Before trying the microwave, I was using the cider vinegar with dish detergent in a bowl plus another bowl using beer. Both had worked, but I had so many fruit flies it seemed like it would never end.
Along with the vinegar/beer dishes on the counter, I had used sticky mouse traps and turned them with the sticky adhesive on the outside. I did get some that way but the microwave worked the fastest. I also got rid of any food source that would attract the flies. I also removed the trash out of the kitchen every day.
My husband said this is my craziest idea yet, but was happy with the results. It worked and worked quickly. I don't think I could have taken one more day of those fruit flies in the kitchen.

Does putting a cup of vinegar on the counter catch and kill fruit flies?
Yes, but you have to put a few drops of dishwashing liquid in to break the waters/vinegars surface adhesion. That way, the gnats or flies drown. Other wise, they will just land, drink and fly off. It works great.
