An insect growth regulator end-use product to kill stable fly in the manure of beef and dairy cattle. A nutritional supplement containing diflubenzuron* for continuous feeding to cattle through stable fly season. Review: Works great! - Barely a fly on any of my cattle this summer. Well worth the cost Review: It’s a miracle! - 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.

It’s a miracle!

Not sure if it works
We had a big fly problem this year. Not sure if it had any effect on lowering the flies on our cattle. It’s very expensive

Seems to work
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.

Cattle licking it, giant reduction in flies
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.

Got it and anxious to see it work.
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….
