well, ... i deal with fruit flies by putting a thin little hard plastic cover on the top of my wine glass that i just poured for myself and friends,...and i always put a top/stopper on an open bottle of wine (these are available anywhere especially neat/novelty ones at wine stores). I do this because i am really anti-bug-in-my-wine type of guy. Apparently, there is a way of getting any flies out of the home atmosphere/environment by placing white wine vinegar in a glass (about a half inch or so, along with dish detergent--just a couple of drops of this,though) and that is it! ... in the morning all the fruit flies will be at the bottom of the glass gauranteed .... this is a recipe from my sister-in-law and she swears by it ...i have yet to try it though.
