People are seriously concerned if I have lost my mind, but today I succeeded in putting many fruit flies in my kitchen outdoors. The methods on the internet offered many ways of killing fruit flies, but in keeping with my videos on catching and releasing common house flies, I wanted a more humane solution.

Those YouTube videos were from years ago, and the house flies haven’t evolved any evasive maneuvers yet. However, fruit flies are a different kettle of fish. I caught a few that way, but there are too many, and catching one scares many away. When fruit flies have landed on a corner edge of a cabinet, it is impossible to place a transparent cup over them without leaving space where some will get away. Holding the cup at a thirty-degree angle and sliding it quickly over a column of them will catch many because they don’t fly until they are startled, but some get away.
A more successful method was to place the kitchen fruit and vegetable trimmings in a plastic shopping bag and leave a cup-size opening at the top. After a few minutes, many flies would land on the stuff in the bag, and I would slowly move the frosty cup over the opening and gently close the top. A jiggling of the grocery bag would startle them, and they would fly up into the cup. But, of course, it was easier to close the bag and put the whole thing on my compost pile in my backyard.
However, I discovered that when the fruit flies were startled, they would fly randomly for a second and then head toward the light as a direction of escape. So I evolved my thoughts quicker than the fruit flies evolved their genetically developed escape behavior. I opened the kitchen window directly over the kitchen sink where the fruit peelings are collected and then startled them. Most of them flew up and out the window. I got a dark towel, approached those located on corners from their dark side, and herded them toward the bright light of the open window. That worked better, and after waiting a few minutes and repeating that strategy, I couldn’t find any more fruit flies.
I hope I have convinced you that I am smarter than a fruit fly and not crazy.
