Composting Can Reduce the Number of Stable Flies
Composting your manure can reduce the number of stable flies on your farm. In a study done in Florida, soiled bedding was placed in a compost pile and turned every few days. The heat of fermentation in the pile greatly lowered the survival rate of the fly larvae and reduced the number of adult flies. (And it is great for your garden too!)
