From about 7 am to well into the night I have my back door open to keep fresh cool air flowing through my house.
I have tried several methods to get rid of the fruit flies and have not had any releif from it. As the cooler months come, I have less and less, until it is too cold out for the fruit flies to survive.
I was re-reading an apple cider vinegar eBook on my Kindle , and came along something called a apple cider fruit fly trap. I was VERY skeptical that it would work.
Step 1:
Fill up to the top of a shot glass, with apple cider vinegar, and cover the shot glass with tin foil.Secure it with a rubber band and using a toothpick poke holes in the top.
*Note* the more holes you poke on top, the more flies will be going in to take an apple cider vinegar bath.
THIS IS REALLY IMPORTANT:
When you go to remove the tin foil, submerge the whole thing in a pan or sink full of water, sometimes the flies are just trapped under the tin foil, and have not taken a bath yet, so when you remove the tin foil, you will be releasing them back into the AIR, but if the whole thing is submerged in water, when you remove the tin foil, they will die in water. I then rinse the shot glass an start over.I also have a video of this fruit fly trap in action on my YouTube link here.
