SmartBug-Off® Pellets is rated 3.8 out of 5 by 1462.
Rated 1 out of 5 by from Not seeing any difference. I’m pretty disappointed in this supplement. My horse has just as many if not more big, itchy bug bites on his inner thighs and belly than he has had in the past with no feed through insect control supplementation. He is miserable. I use a fly sheet, fly spray, topical fly ointment and fly mask and boots as well. I think I will be discontinuing this in his future SmartPaks. Too bad. I really had high hopes. Also, the strong garlic smell is a bit off putting for him as well. He seemed less enthusiastic about his feed once this was added to his SmartPak.

Rated 1 out of 5 by from No go for my mare. My mare stopped eating her supplements with grain as soon as I added this one to it. Since she wouldn't eat it I can't evaluate it's efficacy.

Rated 5 out of 5 by from Love this product! I have been using this product on my mare for years now. Prior to this product, she would scratch and itch so bad that she rubbed herself blood raw all over and would need steroid shots to help her. Once I started using this product April-Sep (we are in the Southeast) she no longer needs steroid shots!

Rated 5 out of 5 by from Amazing product! This supplement worked like a dream! My horse was always getting bit. Once I started using this, no more bites! My horse is sooo happy! Thanks smartpak!

Rated 1 out of 5 by from Not effective This product did not achieve fly deterrence and definitely not control after several months of use from March thru September.

Rated 1 out of 5 by from Doesn’t work Both of my horses have been eating this for months and they are still swarmed with flies. I’m incredibly disappointed that I’ve wasted my money all summer.

Rated 1 out of 5 by from Nope! Didn’t work for my mare. Used it for one month and seen no change. Maybe it’s the bugs in our area but won’t be buying it again.

Rated 5 out of 5 by from Seems to work! So far so good! All horses eating it and seem To have less bug bites!

Rated 5 out of 5 by from SmartBug-Off Pellets I've used this for a little over a mth. I understand it will probably take 2 mths to see the difference, but I believe I'm already beginning to see the difference.

Rated 3 out of 5 by from They seem to help but I hate the package, I cannot get it to stay closed and it seems to attact roaches to my feed room, and gross!!! Product seems good, packaging stinks. The lid won't snap shut and stay that way.

Rated 5 out of 5 by from Saves my horses in the summer! One of my chestnut horses gets horrible welts from mosquitos and flies in the summer. Bug off really helps and they eat it all up.
Date published: 2021-08-12
Rated 3 out of 5 by from I’m not sure how well it works My horse has been this since spring. I want to say it works, but I’m not sure. When he is outside he is constantly stomping and swishing at the flies. I would think he should be relatively fly free if it works. He has the same number of flies all the horses have.
Date published: 2021-08-04
Rated 2 out of 5 by from SmartBug Off Pellets doesn't work I bought this looking for more relief for the horses and have been feeding for about 3 weeks and haven't seen any relief from the flies. So, it back to fly spray every night or so. Smart Bug Off spray seems to work a lot better than the pellets. But, nothing seems to be working this year.

Rated 5 out of 5 by from smartbug off pellets purchased in early June as we had an enormous fly issue and it seems to have helped with that.

Rated 5 out of 5 by from Mostly fly free!! Very very few bugs around my Paint.....this year is easier with BUG Off! Thanks
Date published: 2021-07-25
Rated 2 out of 5 by from Have not seen any results, horses still bothered. I have 5 horses on this and they are still covered in flies. I don't think there has been any difference and they have been on it 3.5 months now. I also use fly predators and Solitude IGR. Unfortunately my neighbors have horses and cows and don't do anything for fly control so I thought I would try this to see if it would help keep the bugs off my horses that are closest to their property. Maybe they would have even more flies on them without this IDK, but it seems worse than ever. :( They do all eat it ok, which I was worried about because it has a very strong odor!

Rated 4 out of 5 by from Surprising benefit I have been trying garlic supplements for several years for my appy who has the tiniest mane and tail His tail hairs end at the tail bone hence trying products to help him fight the flies. This spring I started Bug-off for the first time. Honestly I don't see any difference with the flies on the horses. Maybe helps with ticks because I've been lucky not seeing them on Jack. BUT, to my delight, his mane and tail are growing! I now have about 3" of new growth and still growing. I can only surmise it's the Omega oils. So thank you. I'd given up hope and now I love to brush his tiny tail which I hope will eventually be enough to swish the flies.

Rated 4 out of 5 by from Really works! I’ve only had my mare on this for a couple of weeks, but I'm already noticing a difference in the amount of flies on her. However, I gave it 4 stars because it doesn’t work at all for the horse flies, which are really awful this year. Other than that, they work great!
Date published: 2021-07-07
Rated 1 out of 5 by from No Help Used for a month with no improvement of flies or any other pest. My Morgan mare who will usually eat any supplement hated the taste.
Date published: 2021-06-21
Rated 2 out of 5 by from My horse wouldn’t eat it I started my horse on this to help with the bugs. Unfortunately he’s not a fan of the taste. He’s usually one to gobble his food and usually isn’t very picky, but with this in his grain he ate very carefully and very slowly.

Rated 5 out of 5 by from Great features I have used this the last two year for big season work great
Date published: 2021-05-17
Rated 5 out of 5 by from Really works! We used bug off pellets for our rescue horse, Rory. We ended them too early, without having bugs on him all summer we thought the fall would be ok to discontinue using them. What a mistake within 3 weeks he was hounded, bitten and miserable. Being a northern transplant to the south I didn’t realize that summer lasts until late November so we are back on bug off and feeling happy once again!

Rated 5 out of 5 by from Great product for picky eaters I have used this product for three years on Parker and of all the horses in the barn he has the least fly problem. Plus, he is a picky eater!
Date published: 2020-09-18
Rated 4 out of 5 by from Makes a difference I was waiting for at least a month before I decided if it was making a difference. Last night we cleaned out their shed, which is often swarmed with flies. However this time there were inevitably some flies, but not the normal swarms. I can often see multiple life stages and sizes of flies, but I didn’t notice them this time. Disclaimer: we’ve also been spreading fly predators in their shed for 2 doses now.

Rated 5 out of 5 by from Works to repel mosquitoes! We recently had a TON of rain & the mosquitoes have flourished! Several other horses look like bubble wrap they have so many bug bites, but not my mare! I'm so pleased that this supplement ended up working out so well! For reference, my horse is boarded along the eastern shore of MD

Rated 4 out of 5 by from Working great until I bathed After three weeks I noticed that there weren’t any flies in my white horse and I really didn’t need fly spray (I live in Florida). I bathed my horse with soap and the next day she was completely covered in flies so I am starting from scratch day one. Fingers crossed that it works again and I guess I will just have to have a dirty horse.

Rated 2 out of 5 by from IFFY It has not made a big improvement. I can see a small change. I still have to use DE and other fly control. I have a big problem with this one donkey. Vet said to go ahead and wrap his legs. The flies still try to get thru the wraps. I only have one other donkey they feed off of. I have 12 donkeys, a mule, and 4 horses. The flies only pick on the one donkey and just recently started on the 25 yr old

Rated 4 out of 5 by from Works well! I have put my mostly white, sensitive to bugs, Paint mare on this two summers in a row and it has been a Godsend! Without it, she gets huge ugly welts from bug bites. I hardly see any bites on her since starting this. Love it!
Date published: 2020-07-08
Rated 3 out of 5 by from Smart pac Bug Off I’ve been using this for a month and a half. Pro: both my horses eat it readily. Con: they still have fly bites and the occasional tick. I use this as part of an overall fly control program that includes a feed thru, spray and fly bags. I will continue to use bug off this season but not sure I will for next year.
