Chad Just a dish of vinegar will trap them Save your $$ L.B. Last summer I had an invasion of fruit flies (came with some Vidalia onions that were obviously on sale for a reason...). Large quantities of them, and they're attracted to computer monitors. anyway, someone said that leaving out a bowl of wine will attract them, and they'll die. I did a little experiment, leaving out a bowl of merlot that had been open about 4 weeks, a really cheap sauvignon blanc, and the bottom of a really good bottle of reisling from one of the local wineries. The fruit flies prefered the merlot-vinegar.
