Well according to the website Taste of Home,

The eyes on a fly are more complicated than human eyes; for flies, Orkin says their eyes are compound, or made up of thousands of individual lenses that are very perceptive to changes in light.

So, when light hits the bag of water filled with shiny pennies (or even pieces of aluminum foil, in some cases), the thought is that it refracts and confuses the insects. Overwhelmed, they fly away and hang around somewhere else.

Sounds good and hey it's a pretty cheap solution too, right?

Well it might not actually work according to Snopes, which has been debunking internet theories for years.

They say it's "unproven" right now.

I say it doesn't hurt to try.
