I got this tip (about warding off flies by hanging a bag of water with a penny in it) from my blogger friend Jill ~ (it's within this post HERE).
Mia had come for a play date with Jayden...
...and we went out to play on the little deck and it wasn't long before the flies came to bother the kids. So I remembered Jill's suggestion and gave it a try. And, guess what? NO FLIES!
Even while feeding Eóghan outside! Not one fly to bother us!
Just this one little bag did the trick:
(You can't see the penny in the bag in this picture, but it's in there.)
The side deck right outside our back screen room is tiny, I'm sure you'd have to use more bags to cover a larger area.
I clipped a ziploc baggie to the wind chimes and it's been there for days, through wind, rain, and shine.
Then I tried hanging a few bags from the awning on the side deck by the pool to see if I could ward off the bug problem we sometimes get back by the pool (not only flies, but bees, wasps, and hornets, and I read elsewhere that the water in the bag will keep them away too) but the bags kept falling off. Then I remembered what another blogger wrote a few years ago about her solution to her bug problem. She didn't have the money to buy screens for her awning so instead she got some sheer curtains and hung them from her awning, it didn't obstruct the air flow but it did deter the bugs, so I gave that a try and it's helped a lot too! It especially helps if there is a little bit of a breeze, I don't know how this works either but I think the bugs think someone is constantly swatting at them as the curtains flow back and forth:
