ZIP Lock Bag Fly and Wasp Repeller

This is a very useful tip.

We went to our friends’ house for breakfast and sat on the patio beside the house to eat.   We happened to notice zip lock baggies pinned to a post and a wall.  The bags were half filled with water, each contained 4 pennies, and they were zipped shut.  Naturally we were curious!  Our friends told us that these baggies kept the flies away!  So naturally we were even more curious!  We actually watched some flies come in the open window, stand around on the window sill, and then fly out again.  And there were no flies in the eating area!  This morning I checked this out on Google.  Below are comments on this fly control idea.  I’m now a believer!

Fill a Ziploc bag with water and 5 or 6 pennies and hang it in the problem area. In my case it was a particular window in my home. It had a slight passage way for insects. Ever since I have done that, it has kept flies and wasps away. Some say that wasps and flies mistake the bag for some other insect nest and are threatened.

Regarding the science behind zip log bags of water? My research found that the millions of molecules of water presents its own prism effect and given that flies have a lot of eyes, to them it’s like a zillion disco balls reflecting light, colors and movement in a dizzying manner. When you figure that flies are prey for many other bugs, animals, birds, etc., they simply won’t take the risk of being around that much perceived action. I moved to a rural area and thought these “hillbillies” were just yanking my city boy chain but I tried it and it worked immediately! We went from hundreds of flies to seeing the occasional one, but he didn’t hang around long.
