Has anyone tried the fly repellant method of hanging a closed Ziplog bag (or a few of them) around a stall, with the baggies filled halfway with water and containing a few pennies?
And does it work?? prays for Yes
There are a couple of theories as to why this does work, among them, flies are confused and repelled by the refractions of light created by the pennies and water. There are other theories, too.
Yes, saw that…I’m looking for anecdotal results from my trusty horsey friends here on COTH :winkgrin:
One of the TV shows debunked it. It doesn’t work.
Mythbusters busted it.
I actually bought one of those kits with the bags and all. It said to triangulate the bags and then the area within the triangle would be bug free. It worked at one barn where my horses had one small paddock attached to their stalls because the bags have to be close to each other to work. Didn’t work in big pastures.
does not work
I didn’t have any luck with it. You are better off doing the fly catcher bags. They do work.
Doesn’t work at all 
There have been a few threads about this in the last year or two. The Mythbusters found no significant effect, and I have personally witnessed at least as many flies a
in a barn that had bags of water/pennies over every point of entry as in any other barn I’ve spent much time in. The pseudoscientific explanations folks like to use to justify doing this don’t check out.
