Mineral

[herofan]

What would the fly population on cattle be without any form of fly control? Would their body be practically solid with flies? There are no cattle on neighboring farms here. We use the fly control mineral, back rubbers, and an occasional spray, and the cows still have some flies.

Getting rid of "all" flies is impossible. We can only try and reduce the numbers.

That;s been my experience. It just seemed in some other posts that some were practically fly-free just using one thing.
