With the doors opening and closing all summer, construction going on, etc. and DH bringing in a couple of "wounded" tomatoes from the garden, I have some fruit flies. Not a lot but I don't want them to become a lot, and in fact, I want these ones to die, as cruel as it might seem. I saw one suggestion; covering a bowl of cider vinegar and a little oil with plastic wrap, poking holes in it, and they "fly in but can't fly out". Any other suggestions? Are there sprays that will kill them without making everyone glow in the dark?
