Product Summary:

Combines botanically-derived pyrethrins with cypermethrin to form a fast-acting, long-lasting fly control formula that protects against 6 species of flies, mosquitoes, gnats, fleas and ticks for up to 14 days. Contains a sunscreen which protects against both forms of the sun's harmful, UV rays. Water-based formula won't irritate even sensitive-skinned horses. Unique water-resistant formula contains a special conditioner that binds to the hair shaft so it keeps working even in moist conditions or when the horse sweats.

Usage and Directions
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 14™ Fly Repellent.

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.

Rated 4.7 out of 5 by 18 reviewers.
Rated 5 out of 5 by Only Fly spray used at our barn. We have used Tri-Tec fly spray on our horses for over 10 yrs. It's the only fly spray product that last longer than any other fly spray on the market. We would rather pay more for a product that really works longer than for a product that does not. There is nothing better! August 17, 2010
Rated 5 out of 5 by Gentle Formula I always bought Farnam's Bite-free by the case for years, it works excellent. But my newly bought AQHA dark gold palomino gelding would burn and peel from Bite-free. Poor guy, SO I tried this Tri-Tec 14, still Farnam company, seems to be similar ingredients. My horse NO LONGER gets burned with skin peeling from this, and NO MORE FLIES or mosquitos. I apply every day (we have VERY HOT weather, they sweat ALOT here) because he is hosed off daily, and when he's dry (just a few minutes in Phoenix summer) I apply every evening, and it lasts with no tail swishing, no stomping, no head shaking, until I hose him off the next night. I will be buying a few gallons to last the summer for all the herd. Happy horse, happy me. If you have a sensitive skinned horse that peels and burns from other fly sprays, give this a try.

Rated 5 out of 5 by TriTech 14 fly spray This is the best fly spray I've used yet.Doesn't last the 14 days but a touch up every few days does the trick keeping the flies off, Doesn't peel my horses skin off like ultrashield or the other sweatproof products out there.Big thumbs up for it!

Rated 5 out of 5 by Tri Tec 14 this is the best stuff to assist with flies and other pest. It doesn't last 14 days but it last longer than any other product out there. It conditions the coat and it has a pleasant sent. It works best when the dirt is brused away then sprayed on body area. I rub onto face and around the eyes. If used every few days it seems to work better. Usually about every three or so days and a fly mask helps. State line Tack has the best price on this product I have checked everywhere and the prices on the wormers are usually better. Hope this helps! July 20, 2009
Rated 5 out of 5 by Tri-Tec14 My horse is outside all day in the summer and as you can imagine the bugs are horrible. We do trail rides and the bugs just never leave her alone, no matter what I do! After buying this product, the severity of the bugs has been cut in half, if not more! I recommend this product to everyone! Thankyou Tri-tec 14 July 20, 2009
Rated 5 out of 5 by Absolute Necessary Product Tri-tec 14 is an absolute must have on hand! Great Stuff! Apply every 2 WEEKS. Flies drop dead as you spray it on! When I moved to the Eastern Shore VA, I had a real problem with tics and mosquitos. When you apply it the first time, tics drop off! If I need it heavy duty because my horses are out 24/7 in the woods, I combine it with the Fly-rid Spot on. I have found the best price at horse.com even with shipping. July 19, 2009
Rated 5 out of 5 by TriTech ended fly problem We had been using inexpensive sprays. By afternoon, the 2 mares had fly's. Purchased another brand, after reading the reviews on your site, took it back, bad reviews. Purchased TriTech locally in spray container to try, worked great, can easily go 3 to 4 days. We are now extending the spray intervals. Will purchase by gallon from State Line. Our girls are totally fly free. I thank Stateline for the review section, as well as excellent pricing and customer service. Bob Long June 29, 2009
Rated 5 out of 5 by Awesome Stuff This stuff is great! Not only does it smell nice but it works great! I have a paint that was alergic to some fly sprays and I also hated the way they smelled. Tri-Tek 14 works great on him, has a sun block to help keep his chestnut from fading and his pink nose from burning. It's not greasy so it doesnt attract dirt and he's NOT allergic to it. It's the only fly spray I will use on him and I'm very impressed with it. Great stuff! June 5, 2009

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