    SimpliFly is rated 4.5 out of 5 by 216.
    Rated 5 out of 5 by from Peace of mind, good value Bought this for my mini and donkey as the flies really bother my donkey. This is a good value and is a safe product. I think it will take some time to really start working, but it's palatable and I trust the other reviews on this site.

    Rated 5 out of 5 by from No more flies But this about a month ago and I'm so glad I did. Flies are bad this year I'm doing everything I can to keep them down this product has really helped. Highly recommend. Thre plus about it is that he loves it.

    Rated 5 out of 5 by from Excellent Fly Control We have used Simplifly from April through September since 2015 and will probably never stop. We have an unbelievably small amount of flies for a Virginia Farm and other farm owners plus our vet has commented on it as well. In fact, I don’t really consider flies an issue at all on our little farm since we started using this product. We tried predators for a couple years with almost zero success, and I ordered sometimes up to quadruple the suggested amount. Now if they could just make this stuff for gnats and horse flies, we’d be set!

    Rated 1 out of 5 by from I did not like it. I bought this about a month ago and it does not work.
    Date published: 2018-11-30
    Rated 5 out of 5 by from Good if your whole barn is on it I have a barn with 5 horses and being in Florida, in a swamp we have many flies. The barn does not have a fly spray system and we were getting basically carried away. I put all the horses on this and so far the flies are dramatically less. There are still flies but they do not swarm nearly as bad and I've noticed the horses are much happier.

    Rated 5 out of 5 by from Bye bye flies Very happy with this product and my horse gobbles it up.
    Date published: 2018-08-13
    Rated 5 out of 5 by from Actually Works Started using this after moving 5 horses to my boyfriend’s house and flies from the neighboring farm found us and were multiplying like crazy. All 5 horses eat it with no issues and it worked within a week. This product along with fly traps has put Barn house-fly free. We bought the smallest size to carry down the aisle and give to each horse and buy the largest size to refill it from.
    Date published: 2018-08-10
    Rated 5 out of 5 by from This stuff works! I started using this about 6 weeks ago. I saw a noticeable reduction in the number of flies at about 2 and a half weeks. By 4 weeks I estimate fly numbers are 99% reduced. The horses no longer need fly masks or daily fly spray applications. I only wish it was cheaper in SmartPaks so I didn’t have to give it separately.

    Rated 5 out of 5 by from Our fly population was cut by 75% We didn't start Simplify until May but we cleaned up all manure before we did. I have to use additional fly spray very seldom. This product works!
    Date published: 2018-07-23
    Rated 5 out of 5 by from Effective! We have been using Simplifly for years and it works great at reducing the fly population significantly. We still use sprays and traps but even the farrier noticed how we have very few flys compared to other farms. We feed it to our 4 horses from Spring into the Fall and it seems to be a very safe product.
