2. Fill the bag with water.
3. Place 4-6 coins in every bag.
4. Tie off the bag and hang it in an infested area.
Sounds like hocus pocus? Well, there is actually a fascinating scientific explanation for this method.
The millions of molecules in the
water create a special prism effect, meaning they break the light in a
very special way. When you add the coins, a cumulating effect of light
being broken is randomly enhanced.
Flies have a very special way of
seeing. Their eyes are made of thousands of identical lenses, meaning
they see thousands of reflections of the same image.
For a fly, that simple bag of water
looks like lots of disco balls reflecting light and movement in a way
that causes them to be dizzy. Under such conditions, they end up being
distracted all the time and feeling vulnerable to predators.
Flies serve as food for a number of
other animals, and flies who feel vulnerable won't stick around, because
it feels too dangerous.
Not only does this method work, it is
also low-cost and harmless, unlike chemicals that can poison our food,
air and water. It's ironic how sometimes the best solutions are also the
simplest ones!
