Fruit Fly Trap With A Wine Bottle
Well, sort of free ... if you happen to enjoy the occasional bottle of wine at home. It's a common question: How do i get rid of fruit flies?
Well my wife and I enjoy a glass or two of wine with dinner and on a few past evenings when we had finished a bottle and left a tiny amount in the bottom I noticed that the next morning there were several dead fruit flies floating in the remnant wine. Ever since, if I ever notice any fruit flies in the kitchen, I've always left about a half centimeter of wine in the bottom of a bottle when finished and left it on the counter overnight. Voila, a free trap for fruit flies.
Red wine seems to work best, though i suspect it would work with white, and it doesn't take much in the bottom of a bottle to do the trick, Lord knows wasting wine would be a travesty of the highest order. You don't need nearly as much as in the photos included here, just enough to cover the bottom of a flat bottle or make a nice ring around a center "island" of bottles that have a dimple, or punt, in the bottom. Why does it work? Well i'm no scientist but fruit flies are attracted to fermenting fruit and having fermented grape juice as your bait couldn't be a more alluring to them. Once inside the bottle I suspect the remaining alcohol evaporation inside slowly suffocates the fruit flies much like the old jar and alcohol soaked cotton ball did when you made that bug collection project back in grade school. In any case, I've tried other bottles filled with juices or vinegar but nothing really works like wine.
Bon Appetit Fruit Flies and Au Revoir!
