I wrote an article about catching flys for Community Chickens. One of the commenters left this response:
“Take a small cup or bowl and put a few pennies in it and fill with water. It is an old Amish trick. I have seen it used at an outdoor reunion on the tables, and no flies bothered a single thing. It just kept the flies away from the area. I keep one in my garage now”
And then another one added:
“This really works! I use a ziplock bag half filled with water and a couple pennies. You can hang it anywhere!”
Which is why this now sits on our picnic table.
When you have a few minutes, go to that post and read through the comments for some great advice on controlling flies in the coop.

Also, join me on Facebook to find out more about the flock (children and chickens) and see some pretty funny chicken jokes, photos of tiny houses, and even a recipe or two.
I am very skeptical. It would help convince me if there was some logical reason for the penny in water strategy working. Or results from well done testing, with and without. At least it’s cheap.
After a little web searching, apparently there are no definitive tests. http://www.gardensalive.com/article.asp?ai=1004 provides a reasonable summary of what research has been done. Perhaps it’s the old placebo effect rearing its ugly head once again.
At certain times of the year we get plenty of flies. I might give this a go. I’d love to know if it really works and if it does, especially WHY? How fascinating.
The copper ions released by pennies has an anti-algae, anti-fungal effect on my chicken canteens for my flock of hens. Perfectly safe for the birds, and keeps the water clean and discourages “biofilm” in the drinking water. It really works: use 1982 and older pennies only since they are 95% copper. Newer pennies are 95% zinc and can poison the birds in excessive quantities.
Perhaps there is something to this. Flies and mosquitoes are attracted to stagnant water that has biofilm. The copper ions in old pennies probably help keep bugs away by keeping the water clean.
