Fruit flies need fruit, tomatoes are a fruit except that a federal court made them a vegetable, to hatch from eggs and grow into adults. Adult fruit flies live for not more than 30 days so eliminating the source of the adult fruit flies, the fruit, will eliminate your infestation.

That doesn't help me. I don't have any fruit- or vegetables in my room and the only thing wet that could sustain them at all is my aquariums (which is why I think my room is the only room upstairs that they're showing up) and I can't get rid of them. No lid is air tight enough to keep them out and if i could find one like that, the fish would suffocate.

I know this probably sounds silly, but it worked for us once , when we should of tossed the fruit, put a small amount of juice in a cup and they should go for the juice, there is most likely something sweet that they are after, possibly perfume? I have had a few that like to bug me when I am wearing perfume.

Another way to catch the fruit flies is to put juice in a jar, with a lid and poke a few holes in lid or a mesh screen with rubberband, or put cider vinegar in a jar and use a piece of notebook paper and shape into a funnel or you can use a piece of bannana as bait. I would change your fish water a couple of times and also change the bottom of your bird cage a couple of times. I know more work. I hope this works for you. Hummerlover

Put some apple cider vineger in a small jar or cup and add a few drops of dish soap. Place these 'traps' where you are seeing lots of the fruit flies, and you'll find them all in the bottom of the cup in the morning. ;-)

I was going to say just what Rhizo did. I had a nasty fruit fly infestation last week and the cider vinegar/dish soap worked great. It felt like I was back in a college genetics class with all the damn flies! lol

If you have no more fruit, or vegetables, for these wee buggers to breed and live on, and have not had any for around 30 days then what you have now are not fruit flies which will not live in or near an aquarium.

You may need to verify that they are fruit flies.Fungas gnats can also be bothersome and live and breed in different locations. If it is fruit flies then indeed you need to find the source. The traps will work fine if so. If you need to do a light non residual aerosol treatment you need to put a wet towel over the fish tanks and turn the pumps off for a short while. For further info and help,I've written an article about them.
Hope it helps
