    "Simply The Best"

    In Florida, the flies show no mercy. UltraShield is simply the best. My veterinarian even recommended it. We quit wasting money on other products. We buy ONLY UltraShield now.

    "Best spray I’ve found"

    This spray does what it says it will. It keeps the mosquitoes and flies off my hunting dogs for about 10-15 days and then I have to re apply. The trick I’ve found is to spray the animal and rub it in all the way to the skin. I’ve yet to see a flea, tick, or mite on my hounds either since I’ve been using Ultra Shield. Works great for South Georgia.

    "Does Not Work "

    This fly spray does not work for an hour, let alone 17 days. I have "applied liberally" as recommended, and the flies will land just minutes later. I have used Absorbine products for years, and can say their fly spray is a disappointment, especially for the money.

    "A fly spray that really works"

    This is the best fly spray I have used. I think I have tried everything on the market and even home made solutions. This is gentle on the horse's hair and body, but KILLER on the flies. It will kill a fly instantly that lands on your horse while you are spraying. I haven't tried the 14 days that they claim that it keeps working because I only have one horse and a miniature donkey. Lucky for me I can afford to spray them a little more often. It smells good and makes brushing an ease. I highly recommend this spray to all outdoor animal lovers.

    "The Best"

    I've used this fly spray since they came out with it sooo many years ago and I've only tried 4 other brands in that time but they don't work as well as this one! It's gentle even on my sensitive-skin horse as well as the 3 others. It used to keep flies off better than it does now. I used to only have to spray every 4 days but now I spray lightly every day to keep flies off. I'm sure it does work for 17 days on some insects but for the flies it's an every day deal for the summertime. But it is still better than the others I've tried which didn't even last a full 24 hours. I truly rely on this product to keep my horses comfortable and no stomping!

    "Love this stuff"

    I use this once a week 17 days of a horse rolling around at its pleasure is a little far fetched in equine life. I do use this product in my area we had a large amounts of flys other horse owners had complained about bots. My girls never had one. I worm bi monthly on an alternate schedule also. I feel ultra shield kept my horses bot free so far this year. It also works amazing for mosquitos another horror this year. I buy this prduct by the gallon.

    "Best Fly Spray I Have Found"

    This is absolutely the very best fly spray that I have ever used. Although it claims to last up to 2 weeks, I spray my equines with it once a week. They stay basically fly-free the entire time. No other product that I have tried has come even close to this protection. The only insect that it does not seem to repel for an extended period of time is horse flies, but NOTHING rids them of those pests here in Louisiana.

    "works somewhat"

    The product it's self works as well as any other product on the market. It can't keep flies out of an indoor stall for more than an hour. How does it deal with then weather. The "Continuous Spray" isn't more than a dribble of a spray, no coverage at all.

    "UltraShield Fly Control"

    Advertised to last 14-17 days. In May I used this for the first time; it lasted 2 days and that was w/o rain. After that, it lasted one day like all the other fly control products. I cannot recommend it over any other product.

  11. 5.0 out of 5 stars


    Here in the Souith Carolina low country the mosquitos and ticks are a constant problem, (all year) especially where we trail ride. UltraShield is the only thing I have ever tried that even comes close to protecting the horses/

    "Best fly spray "

    This is the only fly spray I can get to work on my horses. It keep the ticks off and flys. You can also use it on your dogs and other livestock. It works great for fleas and ticks on my dogs too. I have a bad tick problem and I was pulling them off everyday but not since I have put it on them?

    "Best I've Used"

    I run a big boarding and training facility in which there are anywhere from 15 to over 20 horses here at any given time. We use what ever fly spray the owners provide so we get plenty of "research". The knats and mosquitoes are particularly bad this year and the ONLY horses on the farm that are not miserable are the ones we used this spray on. It only lasts a few days NOT the 17 that it claims but it at least lasts more than 30 minutes like the others. Rain and sweat does seem to dilute it some but it's by far the best we've used as far as duration. And their coats are all much softer and none are itchy like they get from some sprays. I used it a ton at shows and trail rides and even their mine will be the only horses that are not being bit. You do have to spray it on, let it sit a minute and then wipe it in.

    "Lasts maybe 1 hour!"

    For two weeks, I applied and brushed in this product once per day following the instructions on the label hoping to build it up in my horses' coats. It didn't provide any better protection after all that than if I just sprayed it on. I'm currently using the last of the gallon I purchased spraying my horses 2X daily to help keep flies away at meal time. Also, my dark bay's coat faded in the sun even with this spray which claims to contain quite a bit of sunscreen and coat conditioners. I do like the smell!

    "Wont buy again"

    Certainly did not last 17 days. I had to reapply in less than a week. Continuous spray was difficult to use, I had to press the spray button extremely hard to create full spray. I got about 3 applications out of the 15 oz bottle. I'll try something else next time.
