Help! Flies!

[ZoomuKeeper]

I'm having no see um issues as well (northeast Florida). My No See Ums are all over the inside, as well outside the coop. There seem to be thousands of them.
Last night I put a Black Flag Bug Zapper in the coop.
I also smashed a bunch with a t-shirt.
This morning, most all were gone. The Black Flag Bug Zapper is working nicely. I was able to shake lots of dead No See Ums out of it this morning.
I also just installed a small fan in the overhead of my coop to blow these little devils out.

I have a box fan in my coop. My coop is 8 x 10 with wood floor and deep bedding. I have the fan in the window which is high enough not to cause a constant dust storm in the hen house. Flies are minimal. they have a hard time flying in as do the wasps. so I am happy. Cheap, non chemical solution for me

Can you post a pic of a fly? It would be helpful in working out how they are breeding and then maybe you can eliminate this environment.

My sticky fly trap has been hanging for 2 years, more moths than flies, but not much of anything on there. I have 2 fly papers hanging also with hardly anything on them. I leave them up so I can see how breezy it is inside the coop.

In the coop I use a poop board with pdz that I scoop every morning. Deep bedding with pine shavings and a little pdz sprinkled in. My run is deep litter, no flies there either.
