This trap is easy and quick to make, costs nothing and is easily disposed of. At which point, make another.
I have made a number of fruit fly traps following instructions found on the net. All traps had problems. I was not satisfied. Now, I've made my own and so far it seems to be working very well. I may have a winner.
- I took a 2 litre pop bottle and cut it in two.
- I poked a hole in the attached cap. It was easily done with the point of an open pair of scissors.
- I poured a little cider vinegar into the bottom half and dumped the peel from one apple in as well.
- I flipped the top over and wedged it into the bottom.
- Finally, I used masking tape to secure the top edge to prevent the escape of any small flies or tiny larvae (maggots). Yes, fruit fly eggs hatch and miniature maggots appear. Ugh.
After the pop-bottle-fruit-fly-trap had been in use for only a few minutes, it contained half a dozen fruit flies. When I checked after dinner, I found no sign that the little critters were finding their way out. I may be a little quick on this announcement, but I believe I have a winner in this fruit fly trap design.
Why is this so important to me? Well, I have had it with fruit flies. Thanks to all the fruit sitting on my kitchen counter at this time of year, I have a veritable fruit fly invasion on my hands . . . and on the kitchen counter. Ugh. If the fruit is fresh and firm with unbroken skin, the flies won't burrow into the fruit. But they will lay eggs on the surface of the fruit and on surrounding surfaces. Ugh. This is one reason to wash fruit before eating.
