From an email exchange between two innkeeper friends:
"Anybody have a way to get rid of the buggers?"
"Our standard is to drink almost all the wine from a bottle, then set the bottle with a little wine in it on the counter near where the fruit flies congregate. They'll go for the wine (smart little buggers) and then can't find the way out of the bottle (dumb little buggers)--but at least they die happy."
