    Rated 5 out of 5 by from Taste Great! My horses love the taste and it really works!!! I highly recommend SmartPak products!!!!

    Rated 5 out of 5 by from Great! Smells bad but keeps the bugs off I didn't think this would work at all but I gave it a try anyways for my mare who swells from any bug bite. We made it through the summer with no bites and I took her off of it when (I thought) the weather changed and the bugs went away. Well four days later, she broke out in huge hives that all started from one bug bite. The vet suggested I keep her on this product now from March-December.

    Rated 5 out of 5 by from Bug Off - It works! I have waited almost a full fly season to write this review. I started late with Bug Off in April, next year I will start in March. I can honestly say my horse was the most comfortable in the barn. I have used less than 2 quarts of bug spray all year and normally I use at least a gallon or more and he has not had a fly mask on all year because the bugs are not bothering him. I cannot say enough good things about this product as part of a overall fly control, happy horse supplement. I would highly recommend it. It is not an eradicator of the flies landing on him so please don’t think it is a miracle product but darn close. We also use fly predators and have good stable management at our barn. With all those factors together this is a must for anyone that wants to keep them more comfortable and use less pesticides on your horse.

    Rated 4 out of 5 by from It works! We just moved to South Carolina, from mountains of NC, and bought this product to help keep the insects off my horses. I believe it works very well, as I have seen very few flies, but lots of sand gnats. I will continue with this product.

    Rated 5 out of 5 by from My horses love it I bought this product about two months ago it works very well for horses with cuts, when my horses get Florida sores it help keep the flys out of his stall.
    Date published: 2015-09-02
    Rated 4 out of 5 by from Works! I have added this product to my arsenal. Fly predators, fly traps, masks, spray and bug off. My dark horse suffers more than the lighter one and this seems to help. My horse is a picky eater and she likes it. However the non picky eater won't touch it.

    Rated 3 out of 5 by from Jury's still out I can't tell if this product is working or not. My horse still has bites and flies still bug her but I think it's better. I haven't seen any dramatic improvement. I am giving it one more month

    Rated 1 out of 5 by from Didn't notice a difference I was really disappointed after all the great reviews that this didn't work on my mare, and my sister's mare wouldn't even eat it, course she doesn't like apples.
    Date published: 2015-08-25
    Rated 5 out of 5 by from Great Product My mare is super sensitive to bugs and every summer I have to give her a steroid injection because she has rubbed herslf raw from the bugs. This year I tried this product and she hasn't rubbed herself at all. What a difference! I'm sold on this!!
    Date published: 2015-08-25
    Rated 4 out of 5 by from It works I bought a bucket of this to try on my horses to help with the flies. I didn't really notice that much of a difference with the flies but this stuff works on the bloodsucking gnats. I ran out a few days ago and now my horses are covered in welts and hives from those biting gnats. I ordered more bug off right away!

    Rated 5 out of 5 by from Great products! I have a very thin skinned OTTB and he gets eaten alive by bugs in the summer. I decided to try the smart pack bug-off pellets and I have been so pleased with the results. He's still had bites but about 75%less and as a result I have a much less anxious horse!I will be buying these for future bug seasons!

    Rated 5 out of 5 by from Great results! I have seen such a difference in my geldings skin. No more fly bites or itchy spots!

    Rated 3 out of 5 by from Not working right now for those HUGE horse flies I started my horse on this a month before summer hit so it'll be in his system....within just this past month we have had seriously HUGE horse flies, I don't recall seeing them last year, but this supplement isn't doing any good for those...my poor horse is getting ate up and he's biting at the flies and causing alot of sores around his withers and other areas...I am switching to the garlic flakes to see if this will help better.

    Date published: 2015-08-08
    Rated 1 out of 5 by from Better options After 45 days on two yearlings, I really can't tell much difference. Horses don't seem to mind eating it, so if it works, that's a plus.

    Rated 5 out of 5 by from I started feeding this in the spring and the bugs are not biting!
    Date published: 2015-08-06
    Rated 4 out of 5 by from Seems to be working After only a month, it appears to be working. My pony mare used to get horrible sweet itch on her belly and would get welts from fly bites (she's a delicate flower, you know). A month later, the sweet itch is almost gone, and I have seen a significant decrease in the welts she has.It smells strongly of garlic and It took a few days of splitting the dose in half to feed it at 2 feedings for her to get used to the taste, but she's fine with it now.
    Date published: 2015-08-05
    Rated 4 out of 5 by from It is an improvement I have 2 Morgans in Vermont. The Baby has the hide of an alligator...the black flies, deer flies and mosquitoes are annoying, but he is OK with fly coat, fly mask, and fly wipe. His Mother, Duchess, has delicate skin, and gets terrible welts, rubs her mane and tail hair off, loses her fur, and really suffers from the bugs, even with her hat, neckwear, coat and fly wipe. The Smart Bugoff pellets, or Horse Pizza, seems to help keep some of the swelling down and makes her a little more comfortable. Given that nothing works very well, this works better than anything else I've tried.
