Are Reflective Discs Effective Remedies for Flies?

In those times when you visit a stall in the wet market or coffee shop, you can find stall holders put up and hang these shiny water bags and reflective discs over the food areas. What are those actually for?

Now we will let you know the answer: this is in hope that stall owners could keep flies away by deterring them from hanging around their stalls.

Yet why water bags and discs? Water bags and discs reflect light and this important property itself is the key to keep flies away.

How does this work and is this an effective remedy for flies?

Flies are very sensitive to lights

What attracts flies is actually the light reflection and refraction - the reflecting light rays from these water bags and discs confuse the flies and make them fly away instead of landing.

Quick facts: Flies have compound eyes that are sensitive to changing light patterns.

Quick Flies Facts

For flies which happen to fly toward that water bag or hanging disc may get confused by the light refractions and reflection, the key thing to note is that they are only temporarily disoriented. After a while, they may take another flight path to get past these confusing lights and then ultimately, landing on your food.

Although water bags and reflective discs may temporarily discourage some flies from hanging around the stall, some other flies would still get past this weak line of defense. For pest control for flies to be effective, this method does not even work to catch and kill any of the flies.
