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 works awesome The only stuff I've tried that works even remotely. 1-2 days! We have swarms of gnats and masks plus this spray keep our babies happy! Horse.com has the best price by far. I buy the gallon refill. Thanks! April 15, 2013
Rated 5 out of 5 by The best fly spray I've ever used I've tried them all and have had the best results from this one. Perhaps the people who have problems with this aren't shaking the jug/bottle well enough each time they apply it. I have found that if you read and follow the instructions and initially WIPE a heavy application, the results are excellent. It hasn't lasted 14 days, but it has lasted 7 days per application. I've used it for years and will continue to do so. September 1, 2012
Rated 1 out of 5 by Extreme Hair Loss I used tri-tec a handful of times and after a hot ride, I noticed that my horse's hair was falling out (face, chest, belly) and developed hives. July 23, 2012
Rated 4 out of 5 by Pretty good This fly spray smells nice and does a decent job on fly repellant for short term. It doesn't last a day let alone 14, but it's good for a quick ride or giving your horse a little relief. Little pricey for fly spray, but they are all different. More cost doesn't always mean a better product. June 25, 2012
Rated 5 out of 5 by *LOVE* This product Living on the coast of South Carolina, where swamps are plentiful, so are mosquitoes. Tri-Tec protects my horses against them. Two of my horses are also allergic to gnats (which is why I switched to Tri-Tec.) Tri-Tec does a great job of protecting them from gnats and does not damage their skin. April 22, 2012
Rated 5 out of 5 by Farnam Tri-Tec I tried several other name brand expensive fly sprays, but in my opinion is the best, I buy the gallon refill. It's water based and doesn't cause dirt to stick to the coat. Sunscreen protection against bleach-out is important for my palomino. I have not found it to be effective more than 1 day during the humid summer months. My horse recognizes the spray bottle and will stand still in the pasture without being tied while I apply it.

Rated 4 out of 5 by bleaches my black horse I've used Tri Tech 14 for several years and been very happy with it. However, I have a new black horse. I sprayed her belly with it when the black flies first came out this spring, and the next day I brought her in and she had reddish brown circles under her belly and sides. Since it was under her belly, I can't blame the sun. I've learned that black hair pigment--eumelanin--is broken down more quickly by acids than red hair pigment--phaeomelanin. Do you have another product that won't bleach my black horse? October 18, 2010
Rated 5 out of 5 by It keeps those pesky flying bugs away! After using WIPE for many, many years; I tried TRI-TEC 14 two years ago. I haven't found anything better for keeping flies & mosquitos away. The added bonus of sunscreen keeps the AZ sun from bleaching the coats, manes, & tails of the horses. Now three mares trot right up when they see the spray bottle; they love TRI-TEC 14, too!

works well
MARIANNE S on Nov 8, 2015
works great love sunscreen and fly spray in 1!
LAUREN R on Aug 28, 2015
This is a good product when comparing to any of the other top brands. I like the smell and it was on sale. It works as well (or not as well depending on how you look at it) as the other top brands. Have not found anything that really works for as long as they say it should. I do have to spray my horses at least once a day to give them some relief.
ELLEN W on Sep 18, 2015
works for several days. good deal when my horses are out on pasture. works well for mosquitoes too.
