SmartBug-Off® Ultra Pellets is rated 3.9 out of 5 by 386.
Rated 5 out of 5 by from My boy has Insect Bite Hypersensitivity and feeding this saved him from having to be 24/7 covered in fly sheets and boots in the hot summer and rubbing all his hair off. All he has to wear now is a fly mask and light spray all summer long - even in the worst flies (and our barn is pretty bad for those). Definitely worth it for his comfort!

Rated 5 out of 5 by from Worked well I fed this to my horse this summer and noticed less bugs on him. I still needed to use bug spray but the intensity of bugs was much lower. My horse didn’t love the flavor but ate it mixed with his other feed.

Rated 3 out of 5 by from Has some good ingredients But the big container and even ended up doubling up the dose and it's made zero difference as far as the mosquitoes and flies here in Southern Arizona. But as I pointed out it does have some very good ingredients that are going to do some positive things.

Rated 5 out of 5 by from SmartBug-Off saved my filly's summer! I recently adopted a 3 yr old OTTB filly and moved her to NC, where we've had a record hot summer with terrible flies. She must have the most fly-attractive coat I've ever encountered, and she was being eaten alive. I had a great, brand new fly sheet and mask and was coating her DAILY in the Absorbine Ultrashield that is still working great on our other horses. Still, she was being bitten constantly. After 3 weeks of SmartBug-Off, it was like a switch flipped. I ditched the fly sheet (which made her too hot in the upper 90s here) and am using fly spray ONLY once or twice a week! Her quality of life is SO much better, and I'm thrilled to reducing our chemical exposure. She will never go another summer without this product. She also loves the taste, and she's a very picky eater!

Rated 2 out of 5 by from Didn't see any change I saw no change in using the supplement at all. Wanted this to work so badly but it didn't. Didn't see a change in the flies in my girls stall or on her body.

Rated 4 out of 5 by from Happier horses I wasn’t sure if this was really working because my horses were still bothered by flies and stomping some but they didn’t have blood on their legs from bites and I didn’t have to use fly boots. My replacement order got delayed and I ran out. I soon saw a difference with welts from fly bites. It must have been working and I will continue to use it.

Rated 2 out of 5 by from Haven't noticed a difference I really haven't noticed much of a difference. Still have flies all over my two horses. I'll keep them on it throughout the fly season, just incase it is scaring a couple away. We have gone through 2 bags now. My horses enjoy the taste.

Rated 5 out of 5 by from Love this stuff! My horses are definitely happier not having to combat so many flys!

Rated 5 out of 5 by from It really Works!! This year As always I started my Trakehner on SmartPak off Ultra in April. I didn’t start my older TB mare On it because she’s been such a picky eater this year that I thought she would go off her food. Once the May flies (gnats, midgies) were out she was being eaten alive swollen scabs all over her body, despite fly spray and swat. So I decided to give her Smart Bugoff Ultra twice a day, load her up with it and within a week she was repelling bugs and within two weeks there was remarkable healing of the damage that the flies are done. There is no question that this product works from the inside out; the change was so dramatic. I also found that spraying their fly masks with the OutSmart bug spray kept the mayflies from swarming in clouds around their heads. I wonder if the people who have not found good results have just not given them enough or tried it for long enough.
