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 works great and lasts for several days. This is important for my horses on pasture who don't always come in when I check on them, so I can't fly spray them every day.

Works well

Best fly spray on the market. Additionally it has never caused any irritation of my horses skin like some of the pricier brands
NISHA M on Aug 8, 2016
Tri Tec works better than most and has a pleasant, not too strong smell. Country Supply (<a href="http://horse.com" target="_blank">horse.com</a>) had the best price on the internet.

PAT B on Apr 8, 2016
works well
MARIANNE S on Nov 8, 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

GRETCHEN P on Sep 8, 2014
This product works very well and has a complete coverage for 14 days even when it rains, if applied and allowed to dry completely before the animals gets rained on. We have had much success with this spray and will continue to use it.
SANDI C on Aug 15, 2014

Tammy L on Jun 30, 2014
one of the more effective sprays
KATHY B on Jun 19, 2014
This product I have used successfully for years. It lasts as long as it says it will. I use it early and late in the year for ticks--and even in the hottest worst fly time in summer and it always works... I've tried many products over the years and only this one really works.
MICHELE B on May 31, 2014
I have used this spray for several years, and appreciate it's scent, non oily nature and effectiveness.
Pamela R on Apr 22, 2014
We have tried out several fly repellent products. This brand seems to work best to protect our horses from flies and other bugs. We live in the San Diego County mountains, but another product perhaps works better in a different climate. Our vet also advised us to use it daily to protect the horses from viruses.
SANDRA L on Apr 20, 2014
Tri-Tec works the best in our area. We have many mosquitos, gnats, deer flies and horse flies and it works for all them for several days
Suzanne A on Apr 19, 2014

It's the best fly spray I have ever used
Patty E on Mar 12, 2014
this is effective as well!
SHIRLEY R on Aug 21, 2019

CAROL R on Aug 6, 2017
Once sprayed how long does it last please?
A shopper on Jun 29, 2018
BEST ANSWER: I love this priduct. I find it works superior to many other fly sprays. However, I find that I have to re-apply daily. It helps for some bugs longer than 24hrs, but not for all, so I just spray once a day, unless I need to hose my horse down after an application - then, of course, re-apply.
I have a coupon from Farnam, how can I use it here?
A shopper on May 10, 2016
BEST ANSWER: Have no idea, call and ask customer service. Not sure you can on catalog sales??
