    SmartBug-Off® Pellets is rated 3.9 out of 5 by 1342.
    Rated 3 out of 5 by from Too soon to be sure yet I've had one horse on this about six weeks, and started another 2 weeks ago. I will say they do like the taste, no problem eating it with their food. One of our horses has a distinct bug PHOBIA - he hates bugs that aren't even there! I thought this would be a real problem this summer (we just acquired him from a Rescue barn in February) but he's a lot better already. Not sure if it's due to the Pellets or not I'd like to wait and review again when more time goes by.

    Rated 1 out of 5 by from Really not working I had hoped this would make a difference in the attraction my horse has for flies. But there hasn't been a difference. I'm stopping this and ordering Smart whatever to help him at least not have such an allergic reaction to the fly bites he gets. I use fly bags, strips, fly predators, and fly spray to keep the population under control, but my black horse is an attractant!

    Rated 4 out of 5 by from I bought this a few weeks ago and have been giving it to my oh-so-sensitive boy. I honestly wasn't sure it was helping him until tonight. We've had such strange weather so I didn't know it that had anything to do with it. He still needs his flysheet of course, and tomorrow we will try the new one with the neck guard too - but I stood watching him and my other gelding who isn't so sensitive as they ate dinner and guess who was doing all the stomping? Yep - he goes on this as well! It took a day or two to get over the taste but after that it's been readily consumed.

    Rated 4 out of 5 by from My horse loves it! Feeding to one of my two horses. I can definitely see a difference in the amount of flies from one to the other. Have also seen a decrease in mosquito problems.

    Rated 5 out of 5 by from This works well for my mare I used Bug-Off last summer and my mare never got bit by a horse fly. I'd see them around her but never landed. Other biting flies and mosquitoes seemed to leave her alone too. Our pastures have some wet spots and bugs can become a real problem. She has also not had a tick on her too. I do use fly spray too but so does every one else. This combo seems to really work for miss mare. She has no problem with the flavor or smell, eats it right along with her supplement and a few carrots

    Rated 4 out of 5 by from Much happier fly-hating horse Bought this to try on our fly-hating Big Zangersheide despite the "eh" response from our vet. WE DEFINITELY SAW A DIFFERENCE in the barn and outside. We still occasionally use fly spray where they are really bad. We could graze him without him being driven nuts and he was MUCH HAPPIER. Just ordered some for our second horse. Easy to set up order and if auto-shipping, a quick phone call stops shipment.

    Rated 5 out of 5 by from Skeptical at first, but I'm very pleased! We live in the Lowcountry of SC, surrounded by water, swamp and marshland. It is a very bug intensive area. Gnats, midges, mosquitos, house flies, horse flies, biting flies and just about every other blood seeking host you can imagine. I have had this horse 2 years and this is his 3rd summer with me. 1st year was ok, kept him sheeted and he did get rub spots on his face and belly but it wasn't too bad. 2nd year was a disaster, even though he was head to toe sheeted and fly sprayed he rubbed his whole belly and jaw raw, was covered in swat all the time and just unhappy. He presented with both swelling in certain areas, welts and very itchy skin when bugs were bad. We had to take 3 months off work to get through it since I couldn't put a girth on him. I started smartbug off in Feb of '17 since thats when we start to notice the bugs, by march/april they were pretty present. I noticed he was rubbing his face and a little on chest(the usual spots) and almost stopped the smartbug off. I'm glad I didn't! By the end of april he hasn't a single rub or blotchy spot anywhere. He's very happy and comfortable still on 1/2 day turn out with sheet and mask, but I'm not shelling out $20 a week in swat. I think I just hadn't started him on it soon enough. Very pleased, happy to spend the extra $$ on showing then keeping farnam in business because of our excessive need for swat!

    Rated 5 out of 5 by from Yeah no flies! We've used this product going on 3 years every summer. Last year we finished riding and my friends horses back was covered in flies- mine had none. It doesn't help my horse with the face flies but does with horse flies and all the others!

    Rated 1 out of 5 by from Doesn't Work for My Horse I have been using this product per the instructions for over a month and it doesn't seem to be working at all. If anything, the flies seem to be swarming my poor horse even more than his pasture mates. I was so hopeful it would work to bring my guy relief from the pesky flies.

    Rated 3 out of 5 by from Uh oh - my minis and mule won't eat it I bought this without trying a sample due to so many reviews having a great result with palatability. I've just started this with mine at a very small dose to start and no one wants to eat it. My mule picked out the pellets and dropped them yesterday and today wouldn't touch the food bowl the SmartBugOff was in. The others are leaving most of their food and noticeably pushed the food around before reluctantly picking at it. I'm having to scrub all the buckets out. Word of advice.....ask for a sample first because four out of four of mine with not touch it and I've just wasted a lot of money.

    Rated 5 out of 5 by from Not so many bugs! I bought Smart Bug Off for a mare that is sensitive to insects. Although the insects here in Fla. are not as bad as the will become this summer, she was getting itchy in March, when I started her on it. It seems to be helping her already. I wanted it to build up in her system before bugs got bad. I also bought an excellent sheet & neck cover for her to wear later to help (I reviewed it also as excellent). Thank you Smart Pak for attending to our needs!
    Date published: 2017-04-23
    Rated 5 out of 5 by from This really works! Works like a charm! No tick bites! I highly recommend this product! My horse seems to be allergic to tick bites. Every time she has a tick the area around it becomes swollen and leaks fluid. In early March I found her with eight tick bites. I decided that was definitely enough and put her on SmartBug-Off Pellets. She's been on them for about a month and I have only found one tick bite on her! Thank you SmartPak!

    Rated 4 out of 5 by from It works! Most importantly, my horse loves the taste. The flies don't seem to bite him nearly as much as they bite the other horses in his 20-acre pasture.
    Date published: 2017-03-28
    Rated 5 out of 5 by from I was very skeptical I have a couple of horses who just get tortured by the bugs. Poor cremello gets bloody streaks down his hide and fly sheets and masks only go so far. Plus, he's a Houdini and can get out of ANY fly mask. I put him on Smart Bug off last year and it really worked, no more bloody streaks and I stopped seeing an entire fly population camping out on his back. He's a much happier horse.

    Rated 1 out of 5 by from Cancelled, my horse will not eat it. May be a good product but my horse will not eat it so I had to cancel it. It can't work if they won't eat it.

    Rated 4 out of 5 by from Surprising results - helps repel ticks! I put my retired horse on Smart Bug-Off this summer, despite mixed reviews online. He is lucky to spend most of his day out in a beautiful five acre field (he is stabled at night). I didn't notice a change in flies landing on him, but I did notice an even better result. He has had far fewer ticks on him (which in my opinion, is a wonderful result for both he and I!). I am keeping my old buddy on this supplement year-round as deer move through and bed down in his field through the fall and winter. To me, this supplement is worth the money. Thank you Smart Pak!

    Rated 5 out of 5 by from Bug-Off is the Best I have used Bug-Off for several years now and this year, with the amount of rain we have had, I expected trouble with flies and mosquitos, but had a very few days when we had any around. Actually the horses were fine, I was the one getting annoyed! I plan to continue using Bug-Off as the spring arrives.
