Rachel Balducci had a nice post recently that suggested how to deal with those annoying fruit flies at http://tinyurl.com/neqr3s. She said to use a jar with a cone-shaped paper (just like we use in our coffee maker!) to trap them inside a jar with a piece of very ripe fruit in the bottom.
Having nothing to lose and a kitchen counter overflowing with ripening fruit with, yes, you guessed it, lots of fruit flies, I decided to give it a shot. Try this the next time you have the little pests and let me know how it works:
1. Put an overripe piece of peach (or other aromatic fruit) in the bottom of a pint jar
2. Cut a tiny hole in the tip of a paper filter cone (or make one yourself)
3. Set the paper cone pointy-side down into the jar
4. Fasten the cone around the top of the jar with a rubber band
Wait a day or so, then check the jar regularly for tiny critters. When they appear, take the jar outside, remove the paper cone and release the bugs. If you still have any fruit flies buzzing around, set up the trap again.
I was quite pleasantly surprised at how nicely this idea worked. After a short time, there were no more nasty fruit flies, but if they reappear, I won't hesitate to use it again. Good luck hunting!
