This blog has a previous post, I Wouldn’t Hurt A Fly, which includes a still photo, but it doesn’t convey the simplicity of the procedure. So, it seemed a video would help. There are two of them, one shot in a closed bathroom where it is possible to turn the lights off and make the room totally dark. The advantage of that technique is that the fly will stay put, and you can go get a clear plastic cup and a piece of thin cardboard and it will be there waiting for you.
This second video shows a fly trying to get out through a sunlit window and how it will accept a clear plastic cup being placed over it.
This procedure is actually easier than shown in this video, because I was trying to show how I could lift the cup up and down and the fly didn’t seem to mind. Then I hit the window, made a noise and startled him, but he was inside of the cup. Also, I got tangled up with the drawstring for the curtain which confused both me and the fly. When I do the procedure more quietly and more slowly the flies stay perfectly still; it is almost like they are hypnotized by being surrounded. Their genetic programming is to flee when something opaque approaches quickly, but a ring of fuzzy light doesn’t seem to trigger their flight response.
It helps you develop a habit of kindness towards others, even flies, and toward yourself. When you are intentionally kind to flies you will be kinder to your own self and be a happier person. It is easier to practice being kind to flies than to people, because people are more distracting and we forget what we are trying to do.
