Amazingly Effective, Nontoxic Fly RepellentUpdated: January 25, 2018 Green Living
The class was visiting a petting farm with a large open barn where donkeys, horses, goats and other livestock were available for the children to observe and interact with.
Despite so many animals in a small semi-enclosed area, there were no flies buzzing around! Curious, I asked the owner about this, and he pointed to the heavy duty plastic bags partially filled with water hanging over every stall.
He explained that a clear bag of water with a penny at the bottom would repel the flies very effectively. He went on to explain that the “eye” of a fly is actually hundreds of eyes and the reflection of light on the bag of water keeps them away.
“Why the penny at the bottom of the bag?”, I asked.
Grandpa the farmer answered that he wasn’t exactly sure but the penny did seem to increase the effectiveness of the hanging bag of water alone. He added that he didn’t know how many square feet of area each bag covered so he just put a bag over every animal stall to keep as many flies away as possible.
He also had put up a few bags over the picnic area and it was so nice to be able to eat lunch without flies swarming everywhere!

Fly Repellent Only Works for Flies
Please note that this fly repellent trick only works for flies, not mosquitoes and other insects. It also works very well for flies in the Southern United States. However, it may not work as well for flies from other geographical areas such as blow flies in Australia.
