Helps your horse say goodbye to flies

  • Provides higher levels of the key ingredients in the original SmartBug-Off formula
  • Increased MSM & omega 3 fatty acids from fish oil promote healthy, resilient skin
Is your horse tormented by flies as soon as summer arrives? If insect season leaves him miserable and uncomfortable, SmartBug-Off Ultra will provide him with the ultimate in fly defense so he can say goodbye to flies.

SmartBug-Off Ultra is ideal for sensitive horses and for any horse living in an area with an abundance of insects. To help deter biting insects, this formula provides higher levels of garlic, brewer’s yeast, and apple cider vinegar than the original SmartBug-Off formula. It also contains omega 3 fatty acids from fish oil and 4,500 mg of MSM to support a normal inflammatory response and promote healthy, resilient skin. Lastly, SmartBug-Off Ultra includes diatomaceous earth to discourage insect breeding in manure.

    SmartBug-Off® Ultra Pellets is rated 3.9 out of 5 by 207.
    Rated 4 out of 5 by from yet to see true benefits I bought SmartBug-Off about 2 months ago and, though, it seems to be keeping the flies away, I also have to consider that it is now fall, and the flies normally die off at this time. The true test will come soon, however, when the tics, start to emerge.

    Rated 4 out of 5 by from Easy to use! When I ordered the first bucket (we are on our second bucket) the customer service agent advised me that the horses might be put off a bit by the garlic odor, and she was right, they were! But I cut back on the amount of grain they got for a few days and they did eat everything, including the Bug-off pellets. Back to normal grain rations now, and no problems - they eat everything! We have a big problem with mosquitoes this summer, and the addition of the Bug-off pellets is lessening the problem.

    Rated 1 out of 5 by from Wish it worked on "no-see-ums" (midges). I was really hoping I would find something to help my Percheron/Quarter from being attached by these horrible pests, but even after making sure I had the right dosage for my 1,500 pounder and gave him Bug-Off every day, it still didn't work. If anyone has any ideas, please let me know!

    Rated 2 out of 5 by from Mixed Feelings Since starting to use this product, my Appendix QH Jasper has had far fewer bloody bites from deer flies during turnout. However, I started using a Bucas zebra-patterned fly sheet at the same time, and I think that's why he has fewer of these. I believe this because the stable flies still bite Jasper's legs. Also, I haven't noticed any change in Jasper's smell, which people have described as a consequence of using an effective feed-through repellent.

    Rated 1 out of 5 by from Don't waste your money!! I started my horse on this product in late May and have continued with it for 3 months in hopes that it needed to build up in his system or something. However, we are 3 months down the road and the flies are 10 times worse (no exaggeration) than they were before I started this product. His stall typically remained relatively fly free minus the occasional 1 or 2 but they were usually blown off by his fans but now they seem to populate by the dozens and there are now upwards of 30 flies low to the ground and conjugating by his hay corner (which is cleaned out daily). My horse won't even stay outside for more than an hour because the flies eat him alive so he's better off in his stall with the fans since the flies tend to go for his legs rather than his body inside. I've tried this, that, and the other trying to get rid of the flies and nothing works. So long story short - don't wast your money!

    Rated 2 out of 5 by from not itching as much on month two for a horse with allergies - the bugs are still on her but she doesn't appear to be rubbing as much. bugs have changed from sand gnats to black gnats which do not bite and horse flies to black flies which both bite...also mosquitoesi am also giving garlic powder

    Rated 5 out of 5 by from Seems to work! Either my TB has gotten tougher over the years (doubtful) or this product really does work! I've had my TB for over 15 years and he's always been a bug magnet - to the point where he traditionally runs to his stall and refuses to leave at certain times of the day as he is anticipating the onslaught of the bugs (and as he does this in the winter as well I now its not a reaction to the bugs themselves arriving...gotta love TB's!). I have typically relied on fly sheets and lots of fly spray to manage this, but when I moved him home a couple of years ago and he was out 24/7 (with the option to use his stall as desired) he was scratching himself raw dealing with the bug bites and my usual methods were no longer working, I tried this supplement...and it took awhile but it really seems to help him. In fact, I haven't had to use his fly sheet in 4 summers! It doesn't keep the bugs off of him or keep him from being bit, but it seems to keep the frequency down to a point that he remains comfortable - and, he's even started remaining out in the field during the times of the day that he previously would run and hide in his stall. I only use it seasonally - I typically start in March/April before the bugs start up and keep him on it through Sept/Oct until the bugs die down and I have to say that at this point, I wouldn't think of going into a summer without it for this horse!

    Rated 5 out of 5 by from Fewer bugs! I started my horse on SmartBug-Off Ultra a couple months ago. I didn't pay much attention to the flies & mosquitoes at first. What got my attention was that I was using less fly repellant than before. There is a definite difference in biting, pesky insects from before I starting feeding Smart-Bug Off Ultra to now!

    Rated 4 out of 5 by from Seems to be helping but the bear took it! It seems like the horses were less appealing to the flies after we started using this product. Although last night the bear took the entire bucket with him. He thought maybe it would help him too!

    Rated 4 out of 5 by from Great benefits and very palatable! I've fed this product to my gelding for about 2 months now. I haven't seen a drastic difference in flies. However, he is the only horse at the barn on this product. He does eat the supplement without hesitation and I don't mind the smell at all.

    Rated 5 out of 5 by from Very palatable I live between two irrigation ditches & am slowly winning the battle of the vicious bugs. My mare would eat this out of my hand she likes it so well.

    Rated 5 out of 5 by from Makes a huge difference My gelding has been on this for 3 months. I purchased a mare that has never been on SmartBugOff and I could she the flies were way worse for her. I immediately put her on it as well. Both horses are happy now.

    Rated 5 out of 5 by from Not being bugged this summer!!! My horse Becky was twitching, stomping, shaking her head and smacking both of us with her tail to chase the flies off her. I wanted a product that was healthy and worked 24/7, not just when I sprayed it on. SmartBug-Off Ultra Pellets has provided great results. She is no longer "bugged" which ruined our rides.
