My Very First 6 Chickens
*~* Livin', Lovin', Learnin' *~*
My free ranging chickens have me following them with a hose to spray their fresh poops. If i leave it, it attracts flies big time. First New chickens, no flies. Chickens now and flies now. My run was too moist a couple weeks ago from misting heavily and the flies were wicked. I went around the yard and added a boatload of dry leaves/sticks/woodsy type material...(brown material) to run and the flies are gone. Also, i will dry out grass clippings and add that brown material as well. I was adding it fresh from the mower bag into run and i had too much 'green/fresh/moist'. After adding brown, the flies have dwindled. Good luck!!There are fly traps with bait- add liquid in bottom, flies go in and die. Many people have success with this.
Fly zappers may work well.
Some people with horses or many animals will buy “fly predators” which are tiny insects that hatch and basically feast on the grubs. But, most effective when you start early in the season - just Google fly predators bc several companies offer them.
You can use sticky fly paper, but not so attractive in your patio-best in other places.
The dog and chicken poop may be attracting them. If possible try to keep the dog and chicken poop farther from the patio or clean it up before fly eggs can hatch.
