With ripe tomatoes, cucumbers and melons in the kitchen, a few fruit flies were noticed this past week. Yesterday morning, I set out a bowl of vinegar with a drop of detergent in it. Covered the bowl with plastic wrap and punched several holes in the plastic with a knife.

In a couple of hours, there were 4 drowned flies in the bowl.

This morning, there are fourteen! If I had been asked how many fruit flies were in the house, I might have guessed half that number. Expecting more, today and continuing.

That's remarkable. It seems odd that either vinegar or detergent would attract fruit flies, yet the proof is in the pudding (or in the vinegar bowl).

another name for them that i didn't hear until more recently is vinegar flies. i've since used a similar recipe as @digitS' for luring them to their doom as otherwise they hover around looking for moisture or are off getting into any things i may have out drying. i don't put plastic wrap over it but just a few holes in the lid so it doesn't evaporate so quickly.

I detest those little flies too and there are plenty that show up when temptations abound. I use the same technique with apple cider vinegar and 3 drops of dish soap. I don't cover the little bowl though, they don't seem to be able to fly out once they go in. I find the technique of putting a piece of banana or tomato in a glass, cover it tightly with plastic wrap and poke a few tiny holes on top to work even better, but disposing of the contents is not as pleasant as the bowl of vinegar.

A bit of cheap wine attracts knats also using the same plastic wrap over the top of the cup technique. I don't add soap and I still catch those buggers!
