Tri Tec 14 Fly Spray is rated 4.594117647058823 out of 5 by 170.
Rated 5 out of 5 by from I have been searching for a fly spray product that would last more then an hour. My donkey suffers terribly in the summer. I have tried nearly every product I could find. All make outrageous claims as to their effectiveness. Tri-Tec 14 has been a lifesaver. I only apply it 2x weekly. I am extremely happy with this product and will definitely purchase it again.

Rated 5 out of 5 by from A must during summer months ! Living in San Diego, we have fly season from about May through October. I use fly predator and a mister and fly spray all summer.

Rated 5 out of 5 by from I love this fly spray. It works fantastic. I have used this for years and it always works much better than other products. My friends' horses will be tormented by flies and my horse is fine. I've also had my friends come back from a ride covered in ticks and not my horse. I do know it makes some horses break out. I am lucky, my horse does not

Rated 4 out of 5 by from Works Well I spray this on my horse and the flies do not bother him.

Rated 5 out of 5 by from The best! This is the only fly spray that works for my pony. The added sunscreen is also great since he is a leopard Appaloosa. Worth the money.

Rated 5 out of 5 by from the only one that works !! We love this product, it last for days and you don't have to soak your horse down for it to work

Rated 3 out of 5 by from Works at first Keeps flies off after immediate use, but would really have to saturate the horse to have it work more than the day and after a roll in the dirt needs to be applied again.

Rated 5 out of 5 by from Works well Have been using Tri Tec 14 fly spray for several years now and have been very pleased with it. It really works well.

Rated 5 out of 5 by from Great product!!! Love this fly spray. Actually makes their coat softer and you don't have to use it every day.

Rated 5 out of 5 by from Best product We've tried many flies sprays in the past, but this one gets the job done!
Date published: 2016-06-21
Rated 5 out of 5 by from It works better than most... I've been using Tri-Tec for years now. I've tried many others but I always come back to T-T. It's non greasy and it works as good as anything does in South Florida where we have flies year round.

Rated 5 out of 5 by from My go to brand I have found this fly spray works best for my sensitive skinned horse. And with free freight shipping it is a deal that can't be beat!

Rated 4 out of 5 by from Good fly spray I like this spray as it really doeshelp keep the flies off my gelding. I alternate different sprays hoping the flies and pesky bugs don't develop a tolerance. ThevTritec is always in my rotation and the one I use the most for trail rides.

Rated 5 out of 5 by from It works. The product works. I was able to catch the sale and get all I'll need for summer. Can't find a better value on any other website.

Rated 5 out of 5 by from One of the only sprays that lasts So many fly sprays work only for a short amount of time, then wear off as the horse sweats. This is one of the only fly sprays that last throughout a workout.

Rated 5 out of 5 by from Tri Tec 14 Fly Spray works very well This product is long lasting and seems to deter all flies, gnats, mosquitos and other flying insects very well. My one pony is sensitive and has broken out with hives with other repellents but has had no reaction to this spray. We do carriage driving so you can't easily swish flies away while on a carriage.

Rated 3 out of 5 by from ok fly spray this seems to keep some of the flies away. I have yet to find one spray that really works well. I did notice that my mare has not come in from the pasture with ticks this fall, so maybe this spray is working better than I realize!

Rated 3 out of 5 by from About as good as ay of them It is fly season here again. I bought this product, which I have used in the past, and was not surprised by the performance. It kept some flies off, but the flies still bothered the horses. I guess I felt better that I had at least done something to help the horses

Rated 5 out of 5 by from This smaller size is just right Fits in your show bag just right! You can easily refill it too.

Rated 5 out of 5 by from Very good product. I've used Tri Tec on my horses off & on for years. It definitely does the job and lasts longer than most other fly sprays ... if not washed off like in the rain, etc.

Rated 5 out of 5 by from Stops Sweet Itch! Absolute Miracle. I have a mare that has suffered from severe Sweet Itch/bug allergies for several years. I have tried almost every oral and topical treatment on the market, spending thousands of dollars, nothing helped. About a month ago, someone told me to try Farnam's Tri-Tec 14, and within 3 weeks, her wounds have healed and her hair is growing back! Apparently the main ingredient, Cypermethrin, seems to be the silver bullet. I had tried most other fly sprays, and even cattle products, nothing else helped. Just wanted to share because I have spent so much time and money trying to help my poor mare....hope this might help others. South Florida area.

Rated 5 out of 5 by from The best by far! We have tried a lot of fly sprays and this one stands up the best in our hot, rainy Florida weather. It smells nice without a "medicine" scent and lasts a couple of days. It may have "accidentally" been sprayed on my own arms and legs in a moment of fly frustration and the results were better than that of bug spray meant for humans. I can't say enough positive things about this product!

Rated 5 out of 5 by from Keeps flies off your horse I buy only tri Tec and have so for years, I have tried others but have always come back

Rated 4 out of 5 by from Pretty good stuff! Most fly sprays seem to work by drowning the flies, if you are able to squirt enough on them. This one actually seems to repel them, making for a quieter ride. It's great to get free shipping, too!
Date published: 2015-07-29
Rated 5 out of 5 by from I have been purchasing/using Tri-Tec 14 Fly Spray for about 20 years. It is worth every penny. When oter products stop working, Tri-Tec 14 keeps the flies away. Good stuff!

Rated 5 out of 5 by from Good Spray Haven't been using long but seems to work well. Will purchase again.

Rated 3 out of 5 by from Tri tax fly spray It worked for my mare n not work for my gelding...? Like to find the right one for my gelding that goes for my mare in one brand...
Date published: 2015-07-24
Rated 5 out of 5 by from It Works! Immediate knock down of flies and other pesky bugs. Seems to last a couple days at least, depending on our weather. Love the trigger and the fact that it doesn't leak. It has a nice spray pattern, too. It seems pricey until you try it.
Date published: 2015-07-15
Rated 4 out of 5 by from Worked well on the flies, but the mosquitoes in MI this summer were too much for the Tritec and the mosquitoes won the battle this year. Went with a different product when this ran out. Still like TriTec, but have discovered one product doesn't always work for every bug from year to year.
