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'!).

Tri Tec 14 Fly Spray is rated 4.594117647058823 out of 5 by 170.
Rated 5 out of 5 by from Really Works Ive tried quite a few fly repellants and I find that Tri Tec 14 doesn't let flies land on my horses!

Rated 4 out of 5 by from Used for Years... I really like this fly spray and have used it for years now. I buy in packs of 6 and have them auto shipped. However, with ANY fly spray I am sincerely disappointed that scientists or product teams for the brand can't figure out how to repel biting flies by now. We were assaulted and mauled by them this year, even with fly sheets on. Human Off repellant doesn't work either. I have gotten secondary skin infections from the bites, I have been bitten so bad this year. I have tried everything including adding Skin So Soft and those very pricy belly balms... Nothing works!

Rated 5 out of 5 by from Great fly spray Keeps my horses free of flies for a couple hours (no topical keeps them free of flies all day that I have seen), and significantly reduces flies all day. If I use daily for 3 or 4 days, I can skip a couple days and still have decent fly control. Also is great for tick control. Costs a little more than some sprays but is worth it for me to see my horses more comfortable. I do use other fly control as well- fly predator's.

Rated 5 out of 5 by from works very well! Have tried many different fly sprays and this one works well and for the longest amount of time. I do advise putting on disposable gloves when applying.(I picked up a case of exam gloves at costco.)

Rated 4 out of 5 by from Costs less in the long run and actually works I used to always use emulsifiable fly sprays to see money, and because they worked adequately. But I had to re-apply quite often, at least twice a day (24 hr turn out). With Tri-Tec, I'm using less each time I spray, it keeps the majority of the flies and mosquitoes away, and because I use less, I'm seeing very little skin peeling, though there is a lot of black sticky build-up that only comes off when they get bathed.
