    Repel-Xpe is rated 4.5 out of 5 by 94.
    Rated 5 out of 5 by from Love This Fly Spray I have used this fly spray for years. We moved our mare from full pasture board to a stable with fly spray provided just over a year ago. We just got a grey TB and he seems to be more attractive to ticks. I put both horses on Repel-X and haven't found ticks since. May be a coincidence, but never had ticks on our black mare that used to be outside 24/7 either. I really like this product and you can mix it 5:1 for more tick protection.

    Rated 5 out of 5 by from Still the best I have used this product 10+ years and it is the best on the market. It's the best value (concentrate), and works great. Won't buy anything else.
    Date published: 2013-05-21
    Rated 5 out of 5 by from Better than most I like the Repel-Xp concentrate because I can mix according to my horses needs. In the summer months I make a stronger mixture and as it cools, I add more water. It's way cheaper than buying the pre-mixed spray and last much longer.

    Rated 2 out of 5 by from Does not work This stuff is a joke. I sprayed my horses legs and body with this stuff and there are still flies everywhere. I practically bathe him in it and within seconds there are flies all over him. I did a test-- 3 sprays on one of his legs and 10 seconds later I find at least 5 flies on the leg. I do have to say I got three bottles of spray out of this concentrate so the value is there. Just wish it would work. I will be trying something else next time.

    Rated 5 out of 5 by from great value This fly repellent works very well and is an excellent value. It sounds expensive for a gallon but since it is a concentrate, you are actually buying four gallons for the price, and it works!

    Rated 5 out of 5 by from fly spray that actually works I have used many,many different kinds of fly sprays. I just wanted one that worked and that didn't cost too much. I wanted to buy a concentrate so I didn't have to keep buying the $20 32 oz spray bottles.This fly spray works and is worth the price. The concentrate lasts awhile too!I highly recommend

    Rated 5 out of 5 by from Great product! I moved my TB to Minnesota from California this summer and the bug situation was quite a shock to him. The first week he was there he had huge hives all over his body and had to have antihistamine injections to calm it down. Consequently, he would stomp all day and I was worried he would make himself lame. I went to my local tack store and bought a strong fly spray which the mosquitoes just laughed at and it was useless. Frustrated I decided for the cost I would by this concentrated version and it has been fab! The only problem I had with it was when I mixed it 1/5 and it was way to strong for him and actually made his skin peal! But, after I learned the correct concentration it has kept everything off! Not the best smelling but gets the job done and a huge cost saver :D

    Rated 3 out of 5 by from Not terribly effective, and OILY! OK, I knew that this is an oil-based insecticide when I ordered it, but I am rather disappointed in just how oily it is! We have a pretty nasty horse and deerfly population at our barn, so I diluted it to the recommended ratio for those conditions. Not only does it smell rather strongly, but I have to reapply it multiple times, just to see results. By the time I do that, my mare has oily, clumpy black streaks all over her. Definitely won't be taking this to the shows!

    Rated 5 out of 5 by from Excellent product and great value I've been using this product on horses for years and years, and I love it. It's by far my favorite fly spray. I find that it works great (even better than the more expensive brands), doesn't make my horse "sticky" like other brands do, and to top it all off, it smells GOOD! I've never had a horse have a reaction to it, but it's clearly strong enough to be effective, and bought in the concentrate form, it's a great value. I would highly recommend this product!

    Rated 4 out of 5 by from Great for the Price I find that this is a very affordable fly repellent. Fly spray can be so costly in the hot and buggy weather. The cheap stuff works for about five minutes, and the really good stuff is too expensive for everyday use! This fly spray does the job and doesn't break the bank!

    Rated 4 out of 5 by from Stall door Staple Have used this forever and it seems to work pretty well. I usually use this as a fly spray for turnout and like that when you spray it the flies actually do stay off. Just be careful of over-concentrating it. I usually stick with the 1:7 instead of 1:4. When its too strong it can 'burn' their skin making it peel.

    Rated 4 out of 5 by from Best Value We've been using Repel-X concentrate over 10 years. Best bang for your buck if you have the time to mix it up. Repels & kills flies, gnats & mosquitoes. With multiple horses this is the only affordable way to go.

    Rated 4 out of 5 by from Does the job This stuff works fine for the price, and it's nice to have the option to mix it at different concentrations for sensitive horses or extra-buggy occasions.

    Rated 5 out of 5 by from Fly spray value With the price of fly spray between $15-20 per quart, the Repel X is a great bargain. You can mix it stronger if your fly problem is bad, or weaker if not so bad. It is the absolute best value. You do need a funnel to pour from the bottle it comes in to your sprayer bottle because it does drip.

    Rated 4 out of 5 by from Reliable for decades I have used this spray since I had my first horse-it's got a very strong distinct odor and has to be mixed, but works as well as anything, and even helps with ticks. I have given several others a chance for "natural" or sunscreen or sensitive claims, but this works as well as any(nothing is foolproof )and economical too!

    Rated 4 out of 5 by from Economical Fly Spray I've used Repel-X for years. Being a concentrate, it's the most ecomonical flay spray that works just as well as the expensive ones. I do have to spray every day though. It has a very pleasant smell.
    Date published: 2011-04-28
    Rated 5 out of 5 by from The only fly spray I use Even with just 1 horse, the cost of fly spray can be astronomical. I find concentrated fly spray to be the cheapest option and Repel XP has been by far the best at keeping the flies away in my area. It doesn't have an awful smell either.

    Rated 5 out of 5 by from All I use! I have used Repel-Xp for two "insect" seasons. I use it at 1:5 dillution and it helps for flies and ticks too! My mare had one tick all spring / summer in 2009 and none this year. Love this product and don't even use anything else for ticks.

    Rated 4 out of 5 by from great fly spray this is an all around good fly spray. I mix it a little stronger than than the directions require and it seems to work great. 4:1 seems to be the formula for me

    Rated 5 out of 5 by from Keep Coming Back I have been using Repel-X for many years. Occasionally I will see a new product and give it a try but I always go back to Repel-X. I like the fact that it repels and kills ticks. And it's a great value.

    Rated 5 out of 5 by from Most economic route I've used RepelX for years....it's by far one of the most economic fly sprays. I like the fact it can be made as strong or mild as you need, and it does not leave a heavy film on your horse's coat, something very important when you're showing. I have tried just about every brand of fly spray on the market, and this is the one I keep coming back to.
