    SmartBug-Off® Ultra Pellets - Equinox 365® is rated 3.9 out of 5 by 210.
    Rated 5 out of 5 by from GReat fly repellent in extreme conditions I used this on my one horse that is used around cattle. The cattle were covered with flys. My horse had very few flys on her and she was walking right beside the cattle. Awesome results.

    Rated 1 out of 5 by from Not sure yet? I haven't seen that this product keeps the bugs away. I have only used it for 2 months. I will wait until next year to see if there's a difference after the horses have been on it longer.

    Rated 4 out of 5 by from Works great for ticks! My 24 year old retired buddy is lucky to spend all day in a huge, beautiful field with tall grass and a stream. He and his turnout buddy have the life! : ) the downsides are a lot of bugs -- flies and ticks from the deer. I started using this supplement to help my horse enjoy his summer more. I can't say I see a difference in flies, but I can say it really helps deter ticks!! I haven't seen any burrow under his mane since starting the supplement (so gross and painful because they caused scabs :( and far fewer on his legs. That right there makes this supplement worth the money!!! Thank you Smart Pak! I also like how this will switch over to an Omega 3 in the winter. Neat idea!

    Rated 5 out of 5 by from Love this product! I have had my horses who are on turnout 24/7 for years. Love, love this product. One because it is not the harsh chemical of some sprays. I do use spray on legs when going out on trails but never do I have to in their field. Save a ton of money on sprays. Never had a problem with the smell or taste. Honestly it is a great product and my horses are picky eaters! Love finding no bites or ticks on them.

    Rated 4 out of 5 by from We purchased a new mate at the beginning of summer and we immediately noticed that she was extremely bothered by flies and insects. We just couldn't seem to get enough fly spray on her and she hated her turnout time. I purchased SmartBug-Off for her and within a week I saw a noticeable difference. She just started her second month on this product and is much more comfortable in turnout and less fussy during riding. We do still need to apply fly spray, but a light application does the trick!

    Rated 1 out of 5 by from Not impressed. We have used several smartpak products with good outcomes. After using this product for a few months. My horse started developing large welts which than turned into small cuts and loss of hair as it caused him to itch excessively. If anything it seemed that the flies were more attracted to our horse. Nothing changed in our horses diet other than this. We had to stop using this product.

    Rated 5 out of 5 by from Great results' Just finished the first month of Smart Bug Ultra. This was my first summer with Boot so I had no idea he had such horrible reactions to flies. I tried so many things and nothing helped. He was miserable and I was desperate! He was constantly chewing on himself and rubbing on trees trying for some relief but this just caused sores and huge knots to develope. I saw your ad on Facebook and decided to give it a try. 4 weeks in he is able to graze and doze relatively peaceful. I am so thankful I took that chance.

    Rated 5 out of 5 by from Super Anti-Bug! We have a horse who has literally been "bugged" to aniexty every year and usually is on 10 zyrtek per day. This year we have put him on the new SmartBug-Off and he is one happy horse with no "fly anxiety"! (and minimal zrytek). Thank you SmartPak for such a great product!

    Rated 5 out of 5 by from Bug-Off Works! I had my doubts, but thought I would give this a try. I was using that greasy fly repellent that you put down the horses back and legs - what a mess! So, when I saw this SmartBug-Off, I ordered it and now I am a believer. The flies seem to have vanished ( or they land once and do not stay). I now only use a fly mask on my horse.
    Date published: 2016-07-25
    Rated 5 out of 5 by from Works well I have used this product for 4 years. I also notice little to no ticks on my horses.

    Rated 4 out of 5 by from Seems to help We have more than the usual amout of niting flies this year due to all the rain. Therefore added SmartBug-off to my fly repellant arsenal. It seems to help as my quarter horse is not running around in discomfort in the early evenings.
    Date published: 2016-07-13
    Rated 5 out of 5 by from Actually works! I looked at this supplement and my first thoughts were "how can a supplement keep bugs off?" and "this is probably loaded with poisonous chemicals", but to my surprise this product had no toxic chemicals and it has amazing ingredients such as vinigar and garlic powder to act as a natural fly repellent! I noticed a difference with my horse (who is very sensitive to flies). Before he was on this he practically lived in his fly sheet and had to be soaked in fly spray, and while he was on this supplement all he needed was the occasional fly spray! This product does not completely deter flies from biting your horse, however, with the occasional misting of fly spray, bugs won't be going anywhere near your horse.
