About Farnam Tri-Tec 14 Fly Repellent Spray

Triple-Action Fly Control

Enjoy bug-free peace of mind with quick knockdown of flies. Tri-Tec 14 Fly Repellent helps you protect hardworking horses from flies, gnats, mosquitoes, lice, ticks, and deer ticks that may transmit Lyme disease. One application of this triple-action fly spray lets you kill and repel flies to protect your horse for up to 14 days, even through sweat and moist conditions.

Create a No-Fly Zone

Farnam’s No Fly Zone horse products provide comprehensive pest protection. The three-step approach includes the SuperMask II horse fly mask to BLOCK insects from your horse’s face, Endure Sweat-proof Spray to REPEL pests, and SimpliFly Feed-Thru Fly Control to REDUCE flies. Together, they help keep insects away from your horse’s face and body, act as a safeguard against six types of flies, gnats, mosquitoes, lice, and deer ticks, and prevent the development of house and stable flies. 

Powerful Defense for Hardworking Horses

Help keep your horse free of flies with a fly repellent that lasts right through sweat and moist conditions. Tri-Tec 14 Fly Repellent fights off six types of biting and nuisance flies, plus gnats, mosquitoes, lice, and deer ticks.

Easy Application

Applying Tri-Tec 14 Fly Repellent is easy—simply brush your horse’s coat, shake the product well, and spray. For application on the face, apply using a clean wipe and gloves, avoiding the horse’s eyes, nose, and mouth. If the horse is dirty, shampoo and rinse thoroughly first, making sure the horse is dry before application. Reapply every 5-7 days initially and then every 10-14 days for optimal coverage. You’ll also need to reapply if the horse is washed or exposed to heavy rain.

Great fly spray

I’ve used this spray for years. It stays on through sweat and hours of riding. I spray my horse after and it appears to work until the next day. Solid product.

Good tick repellent spray

This product does its job well. I use it to deter ticks by applying to my horse's legs, chest, and flanks weekly. He lives in a wooden area with a creek and high tick population. This stuff works!

Helps the fly control

The flies are relentless towards my old boy. This helps a lot! I like the spray nozzle, it doesn't jam like some styles.

Great for Sensitive Skin!

I have a boarder who’s horse has very sensitive skin. Tri Tec 14 is what works best for him. He has not had any skin issues and the fly spray does it’s intended job. I’m well pleased.

Opps on the packaging/shipping

I like this product, it smells very good compared to many others. I've ordered it several times and am so glad Chewy is selling more and more horse products, as our area has lots of horses but no feed/tack store. I just received my order, which came quickly, to find the box wet. The bottle was shrink-wrapped. I'm guessing that's to keep the liquid in if the bottle was compromised. Nothing wrong with the bottle except that the cap wasn't on tight. The product leaked out of the shrink wrap. Fortunately I didn't order any fuzzy toys!

It Really Works on Flies

I have a big Rhodesian Ridgeback (dog - although people say he is as big as a horse) that for some reason, gets covered in flies during the summer. I spray this stuff on him and the flies go away. It's really that simple. It's only good for about one day though.
