JustiFLY Fly-A-Salt Cattle Fly Control - 44 lb Salt Block, 700 Feedings, Feeds 7 Cows for 3 Months

We have used these for 2 years now and they work great. We would highly recommend them . Great product!

Had to wait a bit to see if it worked. Seems to be working very well. Cows just have to go through the block first and it get into their systems. Haven't had to spray them for flies in weeks.

Don't know if it works but cows love it

Like it because it’s available on Amazon's. But I think it’s only for cows….won’t be able to allow horses, or donkeys to graze with the cows. Please update us if we can….

Barely a fly on any of my cattle this summer. Well worth the cost

I’ve been battling flies on my two mini bulls for four years. Spraying them putting pour on, on them and nothing works. There’s plenty of water around so I can’t attribute the non-existence of flies to the drought. I have to say this works better than anything I’ve ever seen. It did take them about a month to start licking it because they’re used to and had a small chunk of their old mineral block. But now that they have there’s zero flies on my porch or at my door! I’ll buy it forever.

This item isn’t returnable so i knew i was taking a chance when buying but i thought in the long run it will help. No lol if anything i see more flies and that’s with also pour on. So my opinion is i don’t recommend bc after months i still don’t see a difference. Very expensive pasture block ornament.

This is the first product that has really reduced the flies significantly, especially on the bull who has always suffered every summer until we started putting this out. One block lasted for more than a month for 8 adults. I put a new block out before the first one was finished.
