It's grape harvesting season here in my neck of the woods. You can smell the sweet fragrance the minute you step out of your front door - yummy ! When you're driving down the road you're likely to see all sorts of grape-y equipment, trucks, tractors, pickers, etc... The trucks are lined up in front of the processing plants loaded with tons of sweetness. However, along with all this sweet goodness comes what I like to call, the scourge of the harvest - the awful, horrible, pesky, creepy, yucky fruit fly. They are EVERYWHERE ! To say I hate them would be an understatement. Now, before all the bug-lovers of the world start freaking out, I don't begrudge their existence. They just need to exist outside, not in my kitchen!
I have learned not to leave fruit out during this season. The little buggers can converge on a bunch of bananas like, well, like flies on fruit.
This is how I handle them. I've looked on-line for solutions. If you've looked you have probably found the same well publicized DIY solution. The cider vinegar in a bowl thingy. If that worked for you - great. It was not effective for me.
I started thinking...if they attack a bunch of bananas as ferociously as they do, why not just give them fruit? So, I smashed up a piece of over ripe banana and put it in the bottom of a paper cup. At this point I tried the paper cone method that is used in the previously noted vinegar trap. Again, didn't work for me. This is what I ended up doing. I stretched a piece of plastic wrap over the top of the cup. I used a round toothpick and punched about 12 holes in it. Then I stretched a second piece over that one and punched 3 or 4 holes through both layers. I wiggled the toothpick a little to make these hole a smidge bigger. Note: If you try this, don't make them too big. Fruit flies aren't the sharpest critters and will easily find their way in but seldom find their way out, unless the holes are too big. I made the mistake of making them too large the first time and watched the little buggers fly in , eat their fill, and fly right back out again. Then I take a rubber band and put it around the cup to hold the plastic wrap on.
Caution: the next picture is gross! Really creepy ! So if bugs creep you out, don't look.
This is what my trap looks like:
The grape-y color around the bottom are the grapes I used as bait, getting all nice and ickey.
And here's a shot of the numerous little devils that fell victim to my trap.
Let me know if you try this method and how it works for you. It's not the most attractive kitchen accessory but it does the trick for me!
