Have you ever had a problem with fruit flies. It seems once they get started they don't know when to stop. They come in on fresh fruit we buy and hatch off as the fruit ripens. Or in my case they are attracted to my worm compost. Beside fruit fly traps cost money, why spend money when you can make a trap for pennies.
I've built and bought many fruit fly traps with little success. Starting with simple jar and stretch wrap with slits in the top. to funnel traps with large funnels. The ones with the slits didn't seem to let out the attractant enough to draw the flies in. Then when they found their way in they sometimes found their way out. The funnel design seemed to work better but it wasn't supper effective. Besides that they where difficult to build and look bulky or where to small to attract the fruit flies.The ones I've bought didn't seem to work either but I couldn't see in them to confirm my victory either. They also cost more money and couldn't be reused.
WINNING THE FIGHT:
I finally took all my research some reading and some experience. I then combined multiple bug trap elements to create my own version of a fruit fly trap. I call it the "Fruit Fly Annihilator."
BEST OF ALL IT WORKS!
