Fruit Fly Trap

For some reason, the fruit flies are ree.dic.u.lous. around here these days. We don't even have fruit on the counter and they're all over the place!
So, on the off chance that you haven't seen this before... here's a fantastic trap that keeps flies at bay or, at the very least, contained.

Place a small piece of ripened fruit in the bottom of a tall glass. {We use a drinking glass.}
Using a piece of 8.5"x11" paper, make a cone with a small opening at the point.
Tape the cone into place so that it fits tightly inside the mouth of the glass.
Run a piece of tape around the mouth of the glass to keep the paper in place.
Sit back and watch it work.
Once you have "collected" most of your flies, pour hot, soapy water into the cup and drown them before dumping it down the drain. 

Another idea is mixing apple cider vinegar, water, and dish detergent in a water bottle. Create the same funnel on the top. The flies will be drawn in and drown. I haven't tried this one but the rumor is it's a great option. 
For a few more pictures, The Idea Room apparently uses it too.

SO GROSS!
