Do Bags Of Water Keep Flies Away?

I read an article that says some people claim that a bag of water can keep houseflies away. Supposedly a lot of people believe this. I have never heard this before and I was wondering why or how this got started. Apparently people that hang bags of water outside their stores or houses never have trouble with flies.

This is a difficult one to swallow. Not the fly, the myth of the bag of water repelling flies. People swallow flies all the time. They don't like it, and they don't necessarily do it on purpose, but they still gulp them right down. I guess a bag of water might be helpful in a situation like that.

But what are the reasons a fly might be driven off by a bag of water. Some claim you must put bits of tin foil in the bags, or even a single penny. That doesn't sound like it holds water. Some people think the flies think the bags are large bodies of water. Others claim the flies see their own magnified reflection, and are scared away. The most popular reason is that the flies don't like the way the light shines through the bags.

Other people say this is all just a myth, and bags of water could never drive away a housefly. Faced with a big tasty meal in the same vicinity of the water bag, I wonder if the fly would really want to leave so easily. There are many who doubt this whole thing. What do you think?

  1. That's a very interesting idea...but, then, it might draw mosquitos.

  2. hmmm, I'd have to see it to believe it. Has anyone tried it?

  3. Hey there,

    I've seen put in practice. I've seen many lawns with gallons of water in the corners of them and always wondered why they were there. It wasn't until someone told me that it keeps flies away. This may be something that may be worth trying out. Later!

  4. I've heard about this and I was wondering if it would work or not but never tried it myself.

  5. Mmmmm...interesting idea...maybe I should give it a there any preference on the colour of the bag????

  6. I have also heard about this and they say it works!

  7. I am intrigued to know if it is really true.
