Bags of Water?
 
My brother in law in an attempt to keep flies away has covered my inlaws house in half full with water ziplock freezer bags. I asked him to explain the idea science, anyhting that would prove he's right, nothing. I looked it up on google and wikipedia etc. and couldn't find science to back it up. Just a bunch of yah it works! We don't know why it just works. I'm sure this is a plot to sell more ziploc bags. Any body know the science behind it and whether it really works?

Think the flypaper companies know about this?

It's common knowledge amongst drain cleaning plumbers that a sudden infestation of baby fruit flies in a house is generally a sign that there's a major leak in a drain pipe (most commonly the kitchen sink drain pipe).

You see, the reason they're called "Fruit Flies" is because they lay their eggs in moist foods of various sorts, but not necessarily fruits. Lots of foods go down the kitchen sink drain, and if they're accumulating in a pile in a crawl space under the house, that's the perfect pile/place for a fruit fly to lay her eggs.

Any time you suddenly get an infestation of small little flies (baby fruit flies) in a house, the first thought should be: "When was the last time I tossed out the garbage?", and "Could the drain line from my kitchen sink be dumping all the stuff that goes down it into a pile in my crawl space, and is that pile now incubating and nourishing a new generation of fruit fly larvae (commonly called "maggots")?"

I'm sure they do. I'm serious you hang bags of water and it's supposed to keep the flies away. The jerk brother in law of mine even added pennies to the last ones that he did.

"Evidently, houseflies, being highly edible and defenseless, are nervous types, and don't like to sit still when they see something moving nearby, because it could be a predator. The water bag acts a bit like a lens--try it some time--in which the movements of people in the area are reflected. Even if the fly is too far from the action to see it directly, it can see a shifting of light and dark in the water bag, which it interprets as nearby movement, and it will fly away from the bag."

Maybe you need to learn how to use Google better.... hehe

I know how to Google. I'm looking for the science of it. Assuming something works because it "works" doesn't mean it works, it means that you have the expected results. All the links you posted were people guessing. Is there a scientist on this forum?

Ya, they hang in the scientific theory sub-forum...

Right, in the "fly behavior" sub-sub-forum. :D

I'm actually disappointed that Nestor didn't post a two page dissertation on the mechanism of the compound eye in the common housefly and its psychoptical implications on spacial perception and flight path.
