Works great on the flies on my longhorns. Initially they did not like it compared to the mineral salt block I was using but once I removed all other blocks from the pasture they grew use to it and had minimal flies compared to last year! Now this block is almost gone. I wish it was not so expensive! About 5 times the price of the other block.

The order arrived 1 week later than promised. (tractor supply fault). I can't tell any difference at all using this product. If anything the flys are worse. I had to give 5 stars for the review to go through. review is blocked with 1 or 2 stars.
