I was very excited, as I currently have an abundance of flies, but was rather disappointed at lack of details and ideas.
This is quite a debate, but DE doesn’t do much. It’s basically overpriced dirt. It certainly won’t do a thing for keep away flies! Don’t put it in feed, either. It’s kind of like putting dry cocoa powder on something-it’s easily inhaled and can cause respiratory issues.
DE is a respiratory irritant, and can cause serious harm to a chickens respiratory system, as well as humans.
Just a thought.
