Flies and Mozzies

Further to the circular email below and my sceptical reception of it, I can now report that careful repeated
tests, with controls,  suggest strongly that this technique does NOT
work, and should be included with the
bottle-of-water-on-the-lawn-to-keep-away-dogs myth.  I may write it up
one day, but I doubt I will get around to it. It does not really seem to
warrant the effort.  However be assured I kept a careful log over a period of months of fly observations in my kitchen both with and without the zippy bags of scintillating water, and with a control object. 

On a related subject, I believe that
empirical evidence I have gathered so far suggests that the eating Marmite every day will stop you being
bitten by mosquitoes
theory is equally invalid. However, there
are several confounding factors to be considered in validating or invalidating this hypothesis, such as the well documented
fact that some people seem to be naturally immune to to mosquitoes,
never being bothered, while others in the same room at the same time are
pestered incessantly.  So it may be that Marmite works for certain
people because of some physiological or endocrinological peculiarity, and may be useful for some people, if not universally.

Hmmm, a pseudo-scientific
explanation that does not make good sense to me.  Were it so, no fly
would ever venture near a river.  and I would not be plagued at the
beach.  Nonetheless, it might work because of some other
explanation… The internet gives no clear guidance one way
or the other on this.  Only one thing to do – Try it.  I shall report in
due course.

The original email:

keep flies away…

We recently went out to
a restaurant with some friends for Sunday breakfast,
and while
we sat in the patio, we happened to notice ZIPLOC
attached to the restaurant’s patio wall. The bags were

half-filled with water, each bag contained four
pennies, and
were all zipped shut. Out of curiosity, we asked the
about the baggies. We were told that they kept the
flies away.
Naturally, we became even more curious.   So we
watched.  Sure enough, some flies came in the open
window, and then flew out again, and there were
absolutely no
flies in the open patio eating area the entire time we
were in
the restaurant!

checked it out on Google and saw several comments from
people who swore that ZIPLOC baggies half-filled with
and a few pennies when attached over entryways will
flies. Some commented that it also works for wasps.

shed light on how and why it works. The comment posted

research found that each of the millions of molecules
of water
presents its own prism effect and given that flies
have a lot
of eyes, to them it’s like a zillion disco balls
light, colours and movement in a dizzying manner.
you figure that flies are basically prey for many
other bugs,
animals, birds, etc., they simply won’t take the risk
of being
around that much perceived action.  I moved to a rural

area and I thought these "hillbillies" were just
yanking my
city boy chain but I tried it, and it worked
  We went from hundreds of flies to seeing an
one, but it didn’t hang around long.

to fly control. It’s hard to believe but it works. If
you have
problem with flies, it would be worth a try. We don’t
many flies, but one is one too many.  


About Uisce úr

Though I am old with wandering Through hollow lands and hilly lands, I will find out where she has gone, And kiss her lips and take her hands; And walk among long dappled grass, And pluck till time and times are done, The silver apples of the moon, The golden apples of the sun.
