Here is what most kennels and dog "pooper scoopers" do to control flies. First they remove all dog poop and place in a trash bag (even inside the trash can). Be sure to keep it tied closed. Use lots of bleach. Trash cans, sidewalks, kennels, even grass, rocks, etc, get hosed down regularly with a bleach water mix. In case you can't use bleach because of turf grass, etc, you can also use Ammonia. Ammonia is actually Ammonium Nitrate which is the same thing used in most fertilizers. So using Ammonia on your yard in small concentrations (it will burn just like fertilizer will) will green up your yard. NO KIDDING! lol
Be sure to use these in a hose end sprayer and adjust accordingly. Usually 1-2 oz per gallon of water. Don't over use or over apply, or these will kill lawns and plants.
Periodically, spray everything with a good quality insecticide such as Bifen I/T. Spray everything outdoors including trash cans, inside and out, lawns, etc.
No fly bait system will control flies in a kennel or similar situation. Most scatter type fly baits cannot be used around pets either, they are very toxic if eaten.
So the answer here is that to control flies in an outdoor environment with pets, takes traps, EXTREME sanitation measures, bleach or ammonia, and a regular pesticide application. No easy fixes here either. Just takes extreme diligence.
Indoors? Different methods apply. CB 80 and the Fly Web Fly Trap are great products for indoor use. Hope this helps.
