Fly prevention

Our barn uses fly predators, and this was my first whole summer there, so I really couldn't comment on whether the fly predators were as effective this year as in previous years. All I know is that suddenly this week, the flies seem to be all over in the barn, with lots of tail swishing and leg stomping going on with Dude and Bestie. So when I read this story about how pennies in a bag of water can deter flies, I was like, hmmmmmm. Actually, my first reaction was "What???? How can that possibly work???" But, if it does work, it only costs pennies! www.botanicalanimal.com
