As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Cover entire surface of animal with spray, but avoid getting product into horse’s eyes or other sensitive areas such as mouth or nose.

    Mosquito Halt is rated 4.7 out of 5 by 172.
    Rated 4 out of 5 by from GREAT for mosquitoes. Not really for flies. So, I'm in Michigan and the humidity is over 9000 most days in the summertime. That means mosquitoes come out to play as early as possible in the spring and will refuse to leave until sometime around Christmas. It's always hard to find a spray that will work, especially if you're like me and want to ride at night after the sun goes down so you don't die from heat stroke. This spray does the trick! No mosquitoes all night! Here's the kicker: No dice with flies. It advertises to work on flies, but I will tell you, they are not phased around here. Sure, my mare gets relief DURING the spray process, but once I'm done, the flies come right on back. This is fine if I'm going to ride after the sun goes down - no flies at that time - but when I want to ride around dusk, they're still a problem. I've been combining this with fly sprays (look for my review of the new OutSmart spray by SmartPak) to get the full effect, but that's costly and annoying to my mare. Other downsides: The smell is strong with this one. My mare acts like she's been a current everyday smoker when I spray her with this stuff and it really feels like I have pneumonia if I breathe it in. Wear a mask or hold your breath. Still, it's worth it to keep those 'quitoes away.

    Rated 5 out of 5 by from Mosquito Halt It seems to work great. My friend who was also in the order is almost out..she says she will get the gallon refill next time since she has so many horses.

    Rated 3 out of 5 by from OK For the bugs we have, this product is not noticeably better than any of the other sprays. Does smell very nice--like kitchen spices. Is a little annoying to have to wear goggles as recommended, and that usually makes me reach for other products first. I realize you don't want to get any of these products in your eyes, but this one has specific recommendations for wearing eye protection.

    Rated 5 out of 5 by from Great fly and mosquito spray I have used this spray for two years now. One of our horse is really sensative to bugs and this spray keeps him happy.

    Rated 5 out of 5 by from Works well, lasts all day This spray also repels flies here. It is long lasting and has a slightly better scent than some repellents. Great for evening riding!

    Rated 5 out of 5 by from Best smelling horses in town I stumbled across Mosquito Halt last summer and it has been a life saver for my thin skinned TB gelding who is terribly bothered by/allergic to the mosquitoes. I find I have to use it daily, but that doesn't bother me or him as it doesn't seem to dry out his coat or leave him too greasy, and we are constantly getting compliments on how good it smells. With 4 horses, I find the highest value in the Gallon refill and know I'll use about two a summer, so I add it on to my Smartpak deliveries when I'm getting low and that keeps me on track.

    Rated 4 out of 5 by from Inexpensive but effective! This is a super effective spray for gnats and mosquitos - especially great if you are near any water. It's inexpensive compared to other fly sprays and still gets the job done. It does have a VERY strong odor, which can take a while to get used to.

    Rated 5 out of 5 by from I bought this about a month ago, we have a small barn, 2 horses and A TON of mosquitos, so many that we had the county out to see if they would spray. The guy from the county said" i've never seen so many mosquitos!!" I use this spray and put a mosquito jacket on the horses at dusk. The spray works great, i've noticed a reduction of bites on both horses,. Keep in mind we have a higher than normal infestation this year too. I will need this product through summer, and will re-order it!

    Rated 5 out of 5 by from Great Product This has been the only spray that seems to work on black flies and mosquitoes. My horse is super sensitive to bug bites and breaks out in hives every year when the weather changes and the black flies and mosquitoes come out in full force. I started using this product a week before the warm weather and bugs appeared and this has kept the sensitive boy happy and bite/hive free. First time in years. Love this product.

    Rated 4 out of 5 by from Absolutely needed where I live. Lots of mousqitoes I have used this product before and this year with all the rain we got the mosquitoes are horrible. The horses will stand quietly at liberty to get sprayed. That's how much they appreciate the Mosquito Halt!
    Date published: 2017-05-03
    Rated 5 out of 5 by from Great Product! The mosquitos get pretty overwhelming here in Florida. Mosquito Halt definitely does its job. We spray the horses all over and lightly over their ears before going out for the night. The people use it too and it works great :) Just try not to breathe it in!

    Rated 5 out of 5 by from Great Product Ordered Mosquito Halt a month ago and just ordered another bottle. It's the only product on the market that I've found to really work to keep fly's at bay. Last almost all day and my horse is no longer having panic attacks trying to get away from the fly's. Very very happy with this product.

    Rated 4 out of 5 by from Here in South Florida with all the rain in the summer, the mosoquitos can be really bad. I find this works better than all the other bug sprays we use.

    Rated 5 out of 5 by from works great this fly spray is amazing for the price and is worth much more. my horse hates the bugs but right as i spray this on her she is fine until i wash it off when i give her a bath after a ride in the summer!
    Date published: 2016-07-04
    Rated 5 out of 5 by from it works!! I like to use all natural repellents but the bugs get so bad I can't stand to see the horses suffer. This works great. Makes me happy to see them eating peacefully and not irritated and constantly stomping and swishing. Great product.

    Rated 4 out of 5 by from Keeps all the bugs off! My horse has a lot of problems with bugs. This product has done very well to keep the bugs and mosquitos off of him. He's now a lot happier. The other big sprays just didn't work as well with the bugs that we get in Louisiana. On a side note, I will say that one of my friends had an allergic reaction to it.
