    UltraShield® Green Fly Repellent is rated 3.8 out of 5 by 87.
    Rated 5 out of 5 by from Smells good a works! Last year was my first year in Florida and I was amazed at the amount of flying insects during the rainy season. I hate using chemicals and found last year that our few local shops would run out of fly spray regularly. I lobe the ga to that you can get free shipping if your a SmartPak member so decided to start buying my routine supplies here!

    Rated 5 out of 5 by from Natural Fly Repellent I appreciate that this fly spray works well for my horses since it is a natural product and does not contain harmful ingredients to them or me.

    Rated 4 out of 5 by from Best "green" spray available I have used numerous green fly sprays in the past and they have just not held up to the torture that is Texas summer. After trying several different things, I came to realization that my mare is allergic to the pyrethroid family of chemicals and cannot be sprayed with my usual my sprays (endure, Ultrashield waterproof, ect.). While she wears a sheet, a neck cover, a mask, and and summer whinnys sox, I still use this spray on areas that aren't or can't be covered (belly). It works as well as one can expect from a green spray and may work better in places where the bugs don't tend to pick you up and carry you away.It also smells really nice, which is saying something because I usually hate the way all fly sprays smell.

    Rated 5 out of 5 by from works and smells great! Have always hated the idea of spraying chemicals on my horse. Was skeptical if this product would work well. Have been happily surprised! In my opinion this product works as well as any fly spray I have used in the past. This is my new fly spray. Gave this fly spray a quality rating of 4 only because no fly spray I have ever used keeps the flies away for more than an hour or so, and on top of that you're covering them with chemicals that soak into their skin.

    Rated 5 out of 5 by from This fly spray smells good and lasts about as long as any other after applying. It does not blister my very sensitive-skinned chestnut mare and she doesn't mind being sprayed with it as she has with chemical sprays. I am going to all natural sprays because of health concerns with the chemical types.....mine and my horses. I liked it well enough to buy another bottle..actually a gallon....to be shipped with my next SmartPak!

    Rated 5 out of 5 by from Smells Good and Works Good Does what it is suppose to do and doesn't smell like most do
    Date published: 2015-10-08
    Rated 4 out of 5 by from Good for a natural fly repellent I bought this last month when I ran out of another natural fly spray I tried this summer. I can't say too much since I have only used this for a month, but, works better then what I had been using. Not sure yet how long each application works for, but, I am going to try this out next season.

    Rated 4 out of 5 by from One of the better green fly sprays Definitely one of the better green fly sprays. Really like that it doesn't have all the chemicals in it but it does have to be applied more frequently.

    Rated 4 out of 5 by from Eco friendly Safe, easy, able to use in barn using predators to reduce fly population without harming the predators. I have used this product all summer, on multiple horses, without incident.

    Rated 5 out of 5 by from Pleasant This fly spray works as well as most and does not give me a headache or cause a numbing sensation in my mouth after spraying... I'm a bit sensitive to insecticides.
    Date published: 2015-09-02
    Rated 4 out of 5 by from Non Toxic and works! I have been using this fly spray during the mo. of August in Illinois. Hot and muggy! This fly spray has worked as well as the ultraSHIELD I used to purchase, and I love knowing there are no chemicals in it that are bad for my horse or me. Was also surprised that the price was basically the same. Love the gallon refill.

    Rated 5 out of 5 by from Great Natural Fly Spray I have used many, many natural fly sprays over the years and this product works the best on my horses. I have one horse with major fly bite allergies and he hasn't had any outbreaks of hives since I started using this spray. Pleasant smell and non greasy which is important since he loves to roll in the dirt. Leaves his coat shiny and great smelling.
    Date published: 2015-07-16
    Rated 4 out of 5 by from Best natural fly product I prefer to use natural fly repellents. Using this combined with Smartpak's Ultra Bug Off pellets really puts a damper on the flies. This product will not last as long as the black label but I truly think it's the best if you want to avoid pesticides.
    Date published: 2015-07-16
    Rated 1 out of 5 by from Poor effectiveness I had questions about the effectiveness of the product prior to purchase but with the amount of rain that we have had all spring and summer, flies, gnats and mosquitoes have been horrendous. So that the amount of regular fly spray we've had to use for the horses to stay comfortable and the level of toxins had me concerned. Since I was already feeding a supplement for insect control, I thought I'd try a friendlier version. I am going back to the old stuff, in order to keep my guys comfortable!! Old stuff is UltraShield EX

    Rated 4 out of 5 by from Green product This is easier on the skin of the foals and broodmares.

    Rated 5 out of 5 by from Really works I use this product daily on my horses, every once in a while I use the Ultra Shield EX Fly spray. I really like the Green with its natural ingredients and it works well.

    Rated 4 out of 5 by from Safe and Great Let me start this out by saying that this is not as good as your "normal" chemical fly sprays (like Pyranha, ect), but if you are looking for something natural and safe to use around you and your horse, this is great. I like to use this in combination with a chemical fly spray since I have a horse that is very sensitive. I spray this on my hands and wipe her face. spray it on her fly bonnet, boots, and also myself on bad days! I recommend it, just be aware that it is not quite as potent as a chemical one.
    Date published: 2015-06-08
    Rated 5 out of 5 by from Great smell and works well. I got this again this year for my two Arabians. It works great on keeping the flies away. I have asthma and other fly sprays make it hard for me to breath when I spray them. This one does not give me any trouble with my breathing.My horses have sensitive skin and this gives them no adverse reactions.I had just fly sprayed my horse and started riding and when I rode by my friend she wow your horse smells nice. It was the fly spray.Works great for needs.
    Date published: 2015-05-19
    Rated 5 out of 5 by from Effective Natural Fly Spray In my area, all fly sprays (chemical and natural) are all working about the same, so being able to use a natural fly spray over a chemical is the better option.
    Date published: 2014-12-02
    Rated 5 out of 5 by from Best fly spray I have ever used When I switched fly sprays I switched to this one. This fly spray could not work better on my horse. There are no bad chemicals and it is all natural. This fly spray is the best I have ever used.
    Date published: 2014-11-29
    Rated 5 out of 5 by from Works well I prefer natural fly sprays and find that this lasts longer than most of them. The smell is also nice - my mare lets me rub her face and ears with this!
    Date published: 2014-09-24
    Rated 4 out of 5 by from Great Eco-friendly fly spray I have been using this product for 2 years now and very happy with the effectiveness and that it's eco-safe. My horse is very insect sensitive and this fly spray is effective in keeping her bug free, although it does need to be re-applied during the day.
