We had a fruit fly infestation a few months ago and needed something to help. We tried the vinegar/sugar/dishsoap method, these traps, and an electric trap with a fan. These sticks don't attract the fruit flies, and they will only trap one or two at random. Putting wine in the bottom part of the stick made them work much more effectively, but it was a little tricky pouring the liquid in. If another infestation occurs, I will be using all 3 approaches - and these sticks seem to carry their weight in the elimination process.
