* Remove all available food from kitchen. Clean the dishes, place open items in ziplock bags or the fridge.
* Open the door of your oven and place a piece of fruit (banana or kiwi peels) in there overnight. (DO NOT DO THIS METHOD WITH A GAS OVEN. Electric ovens only)
* Wake up early the next morning and quietly close the oven door.
* Turn on the oven to 400ºF/200ºC for about 10-15 minutes and majority of your fruit flies will be gone.
* Clean the oven thoroughly.
3. Make a wine trap:
* Put a small amount of sweet wine in a little bowl.
* Take your finger tip and put a very tiny amount of dish soap on it, preferably diluted
* Barely touch the surface of the wine at the center with your finger tip.
* This breaks the surface tension of the wine. The fruit flies will be attracted by the scent of the wine and drown in it. Normally the surface tension of the wine would have protected them from drowning, but with it gone, as they touch the edge of the wine to drink, they will stick to it, fall in and drown.
5. Hair dryer method
* locate the general area of the fruit flies and the nearest plug. Get a hair dryer.
* Plug in the hair dryer, turn it on (preferably to full heat) and put the back end of the dryer near a hovering fly. It will be sucked in and fried by the hair dryer. This is fun and highly effective! Trying to blow at them with the hot air doesn't work well, but sucking them in like this does.
7. Windex
* Windex works great for those stray flies that are still lingering after using the traps. Just point and spray, preferably when they are landed on a surface. Give 3 or 4 good up-close sprays. Eventually they will curl up and die.
