the flies can sense the water being above them. have you ever noticed when rain is coming flies will head for the ceiling? they want to be under cover and protected if they sense water above. so with the water above the doorway it makes them sense that they need to be protected and will fly away from it. ....some flies will still cross the threshold but not nearly as many as before. hope this helped.

what i'm thinking is that flies cant' fly if they have water on their wings, so they do everything they can to stay out of the rain so that they don't get fwopped onto the ground so they hurt their itty bitty heads. Did I actually say FWOPPED? .........geez I guess I DID! Oh well.............and no I don't have a source, it's just an idea I had as to why flies cant fly in the sky when the rain stays mainly on the plain.

I have no idea but my wife's parents do this on their farm and it appears to work. Maybe they get confused or attracted to the light being bent?

They see it and are afraid that if they open the door they will get drenched and then they wouldn't be able to fly away.
