Product Summary:

Farnam Tri-Tec 14 Fly Repellent

Farnam Tri-Tec 14 Fly Repellent is a water-based formula that won't irritate even sensitive-skinned horses. It contains a special conditioner that binds to the hair shaft so it keeps working, even in moist conditions or when the horse sweats. It also contains a sunscreen that protects against both forms of the sun's harmful UV rays.

Tri-Tec 14's combination of botanically-derived pyrethrins with cypermethrin forms a fast-acting, long-lasting formula that protects against six species of flies, mosquitoes, gnats, fleas and ticks for up to two weeks. The 15-ounce size allows spraying at any angle – perfect if you're having trouble spraying your horse's belly. Not only can you cover your entire horse, you only have to do it every 14 days!

  • Quick knockdown and long-lasting protection
  • Keeps working for up to 14 days
  • Water-based formula

Directions for Use:
Shake well before using. To protect horses from horse flies, house flies, stable flies, face flies, horn flies, deer flies, gnats, mosquitoes, lice and deer ticks that may transmit Lyme disease, thoroughly brush the horse's coat prior to application to remove loose dirt and debris. For dirty horses, shampoo and rinse thoroughly. Wait until coat is completely dry before applying.
Tri-Tec may be applied either as a spray or as a wipe. For horse's face, always apply as a wipe using a piece of clean absorbent cloth, toweling (Turkish) or sponge. Wear rubber glove or mitt when applying as a wipe. Spray or wipe horse's entire body while brushing against the lay of the coat to ensure adequate coverage. Avoid getting spray into horse's eyes, nose or mouth. Application should be liberal for best residual results. Reapply every 5 to 7 days under normal conditions for initial applications. As protection builds, reapply every 10 to 14 days as needed. Also, reapply each time animal is washed or is exposed to heavy rain.

This fly spray seems to work best.
Joanne P on Sep 30, 2018
This is the best in my opinion. Has a higher percentage if insecticide than other leading brands. Plus it is not greasy. if you use it regularly for a few days you can skip a few & it still works.
Cindy K on Sep 10, 2018
Best of others on the market
Barbara S on Aug 27, 2018
this brand of flyspray works best on our bugs
kris l on Aug 15, 2018
Of all of the fly sprays I have tried, Tri-Tec 14 works the best at keeping flies off the horses; however, it needs to be reapplied every day.

Never tried before and hoping it will help.
June W on May 21, 2018
I have been using this product for many years and have found it to be the most effective water based spray. I have never had any horse or donkey have a reaction to this product.
Jill D on May 7, 2018
Seems to work well as a non-oil based fly spray. Smell is ok and it has sunscreen which I like for my mare. It doesn't last as long as it says so I have to use it daily when the flies are very bad.
Kathie S on May 5, 2018
Excellent product. I have tried them all, and although they only last a day or two, this is the best one on the market.
T A on Apr 10, 2018
Great product

Camille K on May 30, 2017
Actually works great!
Carol S on May 29, 2017
My horses don't seem to mind this fly spray as much as others. And I love the smell! I also need to apply it less often. Worth the money.
Tracy P on May 18, 2017
Tri Tec 14 seems to last longer than the other cheaper brands.
Susan B on Apr 26, 2017

Carol A on Jan 9, 2017
This product has good ratings from users for longevity and contains all 4 ingredients that make for good fly control. Our use prior to purchase was positive versus other brands we have tried. Price on State Line is the most affordable.
Laura L on Jun 26, 2016
This product works well and has a more pleasant odor then the other fly sprays
Susan H on May 19, 2016
This is by far the Best Fly spray I have used and I have been loyal to this brand for many years. Dollar for Dollar it Works!!
It is so much less expensive to order it here than to purchase at any local supply store. I had to buy a bottle of the 32oz in a pinch when I ran out and it was $26.99.
Wendy E on May 10, 2016
Exceptionally effective . I stopped buying it when the price got out of reach. This one is a special treat for my horse.
David S on Apr 23, 2016
recommended by my vet

We had a huge number of face flies that were driving us and the horses crazy this fall. This helped clear them away.

It just plain WORKS!.. and trust me I have tried them all.
Kylie L on Aug 8, 2015
My mare has a sensitivity to all the other fly sprays that Ive tried. Even the homemade ones with baby oil were a disaster. I found this..not only does it work great but she didn't get any hives...this is the only thing I buy for those pesky flies.
Davina S on Aug 7, 2015
One of the only fly sprays I've found with UV protection
Erik V on Aug 7, 2015
Tri-Tec works better than any of the other fly sprays I have tried over the past 30 years. It is expensive, but I don't have to re-apply constantly.
Amy C on Aug 1, 2015
price and rating
Janet S on Jun 30, 2015
BEST Fly spray on the market !
No daily application. If flies land on the horse, believe me they don't stay.
Flies stay away for several days.
Highly recommended product.

Can you use this on goats?
Lynn W on Apr 20, 2016
BEST ANSWER: Hi. I read the label and it only states for use on horses. The active ingredients are listed, but one is pyrethrin which is potent. I know goats have some "issues" with normal meds that other animals have no problem with, so I might try to find one with a label that states for goats, sheep, etc.... hope this helps.
Would this work on a horse with sweet itch? If not does anyone have any recommendations on what would work? Not looking to spend to much.
Nikki on May 7, 2016
BEST ANSWER: If you mean does it treat sweet itch or can it prevent sweet itch. It is very effective as a fly repellent when used consistently. It is pricey, and worth it. It should be used before the gnats attack your horse and cause the itching/alllergic reaction. Cold baths and tea tree oil shampoo can soothe my horse whne he has reactions to fly bites, but the best thing is fly spray every single day and fly sheet.
