I’m sure I’m not alone stressing about flies this year. They are out of control! We’ve sprayed the pasture twice with no relief. 3 spray-on repellent brands I’ve tried aren’t effective this year. Wondering if a dry lot would offer a reduced fly area for them? My herd makes their own little dirt spots to roll, so thinking of just making it more official. Or is it a lot of work for nothing? Thoughts?
