SmartBug-Off® Ultra Pellets is rated 3.9 out of 5 by 372.
Rated 5 out of 5 by from Doing A Great Job So far I have used a lot of different products, and nothing worked until now.. Hives & Itching are disappearing and helping out greatly
Date published: 2021-07-17
Rated 5 out of 5 by from Smells Great! I have been giving this for 2 months now seems to be helping - we have a lot of Bugs in Florida!
Date published: 2021-07-14
Rated 4 out of 5 by from Worth it I have been feeding this for the last few summers to my two horses and I notice some difference in how bothersome the bugs are. I would guess it’s up to a 30 percent improvement which I think is worthwhile. Of course, I still use fly spray and fly masks too as I want my horses to be comfy. I rarely write reviews, but rely on them when I purchase products so thought I should do my part!

Rated 1 out of 5 by from No effect on bugs My four horses have been on this supplement for 3 months and it has had no effect on flies, deer flies, ticks or horse flies. I started them early in February to make sure the supplement was fully in their system when the bugs came out.

Rated 4 out of 5 by from Hopeful I bought this to help keep the flies away, I’m hopeful to see it as we start fly season

Rated 5 out of 5 by from Bug off I bought this a month ago and the horses are still covered in flies
Date published: 2021-05-18
Rated 1 out of 5 by from Horse didn’t eat My horse was not a fan of the flavor of these and refuses to eat them. He also has had bad diarrhea since he started getting this in his Smartpaks. I am going to empty all of these wells from his remaining Smartpaks. So a pass from my horse!

Rated 5 out of 5 by from Works well We have been using this for our one thoroughbred horse and it seems to work for her. She is less bothered by the bugs.
Date published: 2021-02-27
Rated 3 out of 5 by from Not working yet I bought this a little over a month ago and haven't seen much improvement with my horses bug sensitivity. She also gets fly sprayed down with natural fly spray and wears a fly mask. The bugs around her face aren't as bad and the hair is growing back but she still has hives on her chest and underside her neck. I'll try for another month and see.

Rated 2 out of 5 by from Smells terrible! I’m not sure the effectiveness of this product because my horses won’t touch it. They literally eat everything except these pellets. I’m sure the strong stench of them doesn’t help matters. They smell rancid!
Date published: 2020-09-01
Rated 4 out of 5 by from strong smell Bought a month ago and my horse likes it and he seems to be getting less bites
Date published: 2020-08-14
Rated 5 out of 5 by from Works great!! I have been using this produc for several months I have definitely noticed a difference in the amount of flies around the horses that eat it!!! It’s great!!!

Rated 5 out of 5 by from Happy horses This has helped both of my horses with flies and ticks! I am one happy horse mom
Date published: 2020-08-06
Rated 5 out of 5 by from Fantastic! I started this at the beginning of June this year. My horse had been getting welts from flies the past few years. He is the only horse at the barn (about 30 horses) on it and I've only every seen 1-2 Friesland on his leg and fly right off.
Date published: 2020-07-18
Rated 1 out of 5 by from No luck Unfortunately my horses will not eat it. I can put 5 little pellets into their feed and they will turn up their noses at the entire feed bucket!
Date published: 2020-07-15
Rated 4 out of 5 by from 5 Weeks in and definitely see an improvement... My 26 year-old quarter horse gets terrible "allergies" to insects / insect bites during the summer, especially on his stomach. I began the SmartBug-Off Ultra pellets about 5 weeks ago and definitely see an improvement. He still has some itching and bumps but not nearly as bad as usual. I'm going to keep him on it for the remainder of summer because some improvement is a big deal for him. He needs the relief. I mix the product into his morning bucket and he eats it up no problem.
Date published: 2020-07-15
Rated 5 out of 5 by from Fly control I think it is working and I just bought a bigger bag! I already recommended it to my barn people!

Rated 5 out of 5 by from Convenient and Chico loves them!! I’m glad I started Chico on this supplement ❤️ Hoping he does well on it. He really seems to like them.

Rated 5 out of 5 by from Incredible product A friend of mine told me about this product and she raved about it. So I ordered some and have been using it for about three weeks now. I am amazed at how good it works. My horses, I have 8, have no flies and it's fly season. I've never seen anything like this. And it sure beats fly spraying every day.

Rated 3 out of 5 by from Still Evaluating... My 11 year-old Arabian has developed hives by the end of summer the past 3 years, presumably from insect bites. I am trying this, but been feeding since April 14 and he still has not adjusted to the strong flavor/smell. I mix 1/2 scoop morning and night with soaked beet pulp and dry cob. I add some brown sugar to make it more palatable, but he still pushes it around, but eventually eats it. If it keeps him from getting hives, it will be worth the trouble, but will continue until Fall before I know the results. I have had great results with SmartPak supplements in the past, so keeping my fingers crossed!

Rated 5 out of 5 by from So far it’s worked great I have only used it for 1month, but it has decreased the face flies dramatically.
Date published: 2020-05-19
Rated 5 out of 5 by from Wow! This stuff works! I have a very sensitive warmblood. He was shaking his head and rubbing his mane and tail. Fly gear made him more agitated. I started him on this supplement with not much hope. Well let me tell you, this stuff was a miracle for him. And it started working quickly. No more head shaking, no more rubbing. If you’re having these issues related to bugs, it’s worth a try.
Date published: 2020-05-12
Rated 5 out of 5 by from We have been using this product for years, and my vet and I are in a discussion on whether this product also kills worms as my horse never test positive for worms even though he sometimes shares a field with the cows. Flies still land, and they even sometimes bite, but when you compare my horse with the horses that do not receive this supplement, it is night and day. It works.

Rated 5 out of 5 by from Used for pasted 2 years, great product. Used for pasted 2 years, great product. Yes, I will continue to re-order. Helps with the flies alot. We use lot "bug bags" scattered around the fields as well. My TW/StBr used to get lots of bot eggs on his legs. Well, no more. The QH didn't. Less Horse Flies. Great prodouct. I order the MVP 6way and it has done great on coat, growth of mane and tail, helps hooves (also use biotin). Horses grow with these products.
Date published: 2020-04-22
Rated 3 out of 5 by from Too soon to tell I think my results are too soon they’ve only been taking them for about a week, but we had a horrible rain spell that lasted 10 days and the flies are horrible I don’t want to knock the product as of today because of the changes. I will say that both of our horses have devoured the product. So must taste good
Date published: 2020-03-26
Rated 5 out of 5 by from Effective! Would like to see a 10lb Bag I love this product. It's really helped one very sensitive horse and two moderately sensitive horses react less to bug bites. One used to chew his belly until raw, and rub his mane and tail, every year, without fail. Now almost nothing! Just the occasional itch. I would really like to see the product available in large bags, instead of the bucket. I'm trying to reduce my plastic consumption. Or to see the savings rate of the bucket apply to the slightly smaller bag.
