What do we do about them? We got fly bait. It's in a bag and you but water in it and hang it. we have gone thrue 4 in the 2 last week's. The girl's coop gets sprayed out with the water hose every night and gets scrubbed with bleach & soap once a week. When the bag gets full with flies it STINKS! What else can we do? we don't want to fog the yard because we are afraid it will make the girls sick. Any suggestions?
