Don't know if this really works, going to set up today and check it out. Was forwarded to me by my father and wanted to share for what it might be worth,
ZIP LOCK BAG - Good tip!
"]We went with friends to a restaurant on Sunday for lunch and sat in
the patio section beside the store. 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!
The owner 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!
]I tried the zip lock bag and pennies this weekend.. I have a horse
trailer. The flies were bad while I was camping. I put the baggies with
pennies above the door of the LQ. NOT ONE FLY came in the trailer.
The horse trailer part had many. Not sure why it works but it does!
Fill a zip lock 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. Every 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
I swear by the plastic bag of water trick. I have them on porch and
basement. We saw these in Northeast Mo. at an Amish grocery store
& have used them since. They say it works because a fly sees a reflection
& won't come around.
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.
