SmartBug-Off® Ultra Pellets is rated 3.9 out of 5 by 386.
Rated 3 out of 5 by from Helps a little I have had my horses on this for about 1 month. It helps with the stable flies but not with the gnats, which was my main expectation. I have one horse who gets summer sores around his fetlocks from gnats, it hasn’t helped with that.

Rated 1 out of 5 by from Didn't help biting flies and gnats I tried this on my super sensitive thin skinned horse. I have two so I only fed it to one to see if it was effective I didn't notice any difference in the amount of stomping and biting between the two horses. So I can not recommend this product, especially at the cost.

Rated 5 out of 5 by from Works Wonders for My Horse! SmartBug-Off Ultra Pellets have worked wonders for my horse during the pesky fly season! My horse tends to get bites and bumps from insects during the spring and summer months and after starting him on this product his bites and bumps have gone down significantly. I’ve also noticed that when there is a pile of manure in his stall the flies steer clear and want nothing to do with it. Additionally, my horse tends to be picky with supplements and I was very surprised to find that he ate these straight out of my hand not mixed with anything else! The other great benefit to this product is that my horse has such a shiny coat thanks to the omega 3 fatty acids! I’m incredibly impressed with how well this product has worked for my gelding. I highly recommend giving this supplement a try if your horse gets irritated by those pesky insects.

Rated 1 out of 5 by from Does not repel bugs I bought this SmartBug-off Ultra pellets earlier this spring and had been feeding it to my very bite sensitive horse for a couple of months. Doesn't work. The first time it warmed up she was going crazy. Waste of money. My mare ate it just fine but sure didn't help her any. Have had good luck with some of your other products but not this one.

Rated 5 out of 5 by from It really works! I have a 18 year old mare who has battled sweet itch for several years. Many dollars and a lot of time spent on head to toe fly wear, more than a bottle of fly spray each week, medicated baths, skin soothing gel, stalling during the day, etc. she was still moth eaten, scabby, and itchy. 1 month after starting Smart Bug Off, her skin looks amazing! She is not rubbing on the stall walls, and even her legs are clean and free of bite marks. She currently has a fly sheet with belly band and neck cover and fly mask, but I really think that when the weather gets really hot, she will be OK without them. I’m in Alabama where there are plenty of bugs for an extended part of the year.

Rated 5 out of 5 by from Excellent product This works. I notice a difference in less bugs and ticks on my horse than other horses not using this product

Rated 5 out of 5 by from haven't seen a horsefly last two months We got this because we have a huge problem with flies and gnats. Deep south so it gets bad early in the year and continues for a long time. We still have gnats but not as bad but the flies are not around for the last two months she has been on the supplement. It really is more for flies so I can't complain about the gnat issue. Before we started the Ultra Pellets we had some LARGE horseflies. The big 2" or larger ones. None now. I plan to keep her on it as it really seems to be working at this point. Pleased with product.

Rated 5 out of 5 by from Great product! Our horse has been on the supplements for a month now. We are seeing a difference, especially with flies around her face. We haven’t seen any side effects, which I am happy about.

Rated 5 out of 5 by from The only thing that worked! I have a thoroughbred gelding that had his tail amputated last year. As if he was not already sensitive enough, the bugs this summer were driving him crazy! I tried every fly spray and fly sheet on the market! Nothing seemed to give him much relief for more than a couple of hours. I was running out of options. I was skeptical of trying the SmartBug-Off Ultra Pellets for fear that they would not make a difference or that my picky boy would turn his nose up at the thought of consuming pellets containing garlic! I was wrong! My thoroughbred gobbled the pellets right up and within two weeks of starting the supplement, I noticed a huge difference!. He had significantly fewer fly bites than my other horses that are turned out with him. He also stomps less and is visibly less irritated than the others! This is definitely a Summer must-have for my horses!

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 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!

Rated 1 out of 5 by from Very disappointed in this supplement! I bought this and put all my horses on this at same time so that would be more effective to help against the flies. My horses went from beautiful coats with normal flies to a month on this bug off ultra supplement now they all are covered in scabs from being eaten by flies and the flies now are HORRIBLE! Made them worse!!! (And my horses come inside every night with fans in stalls so they don’t live outside or anything) Very upset with this supplement!

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!
