Gf brought a pineapple over and ever since then the fruit fly population has been increasing. I had taken the Saran wrap out to the garage and I have not remembered to buy more at the store. I attempted to make a trap with a bread bag over a Deli container, but they don't like to use it. I had a 4 pack of Apple Danish. The flys found them. So I used my vacuum to suck them out of the container and then release them outside. It is 2 degrees this morning and I took the container outside and released them, without using the vacuum. That is easier by far. The nice thng about using the vacuum is that I can catch some that are outside the container and also get some as they fly around the kitchen.
