We have sheep, but have never tried on the sheep. We discovered, that if you have chicken free range with other livestock; they have just about controlled the fly problems. They scratch around in manure and eat the fly larvae. Very good results & the eggs are a wonderful gift each day! **Q: How many 360 gram packs are included at this price?** A: Dear Patrick, this price is for a case with 6 packs of Justifly 360gram. You just need to mix a pack into a 50 pounds bag of your preffered mineral (so 6 packs is mixed into 300 pounds of mineral). Just to let you know, one pack of Justifly 360gram can treat 2 animals during 6 months of fly season in average (a case with 6 packs treat 12 animals in the fly season). So, you can control the development of horn fly, face fly, stable fly and house fly for less than $.04/head/day. Simple, economical, fly control! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked well *by T***R on September 18, 2023* Easy to use and worked well ### ⭐⭐⭐⭐⭐ Fly bate review *by S***E on March 11, 2026* Great to control flys when mixed with granular mineral. ### ⭐⭐⭐⭐⭐ I used this product all of 2017. I could ... *by M***S on February 26, 2018* I used this product all of 2017. I could tell there was a big difference using this product. No flys on manure in pasture. And almost no horse flys on cattle. My neighbors don’t use fly control so you will always have a few fly’s. I will be using this product again in 2018. ## Frequently Bought Together - Champion USA JustiFLY Feedthrough Cattle Fly Control, Single | Non-Toxic Larvicide.
