Farnam Tri-Tec 14 Fly Spray for Horses - Long Lasting Protection

In this review of Farnam Tri-Tec 14 Fly Spray for Horses the bottom line is simple: this product is aimed at horse owners who need a reliable, long-lasting insect control option that also conditions the coat. The formula promises up to 14 days of protection and fast knockdown of flies, gnats, mosquitoes, lice and deer ticks, making it a strong choice for stabled or turnout animals where ongoing relief matters. The reviewer found it particularly useful for hard-working horses that sweat, thanks to the water-based carrier and built-in coat conditioners.

Key Features

• Long-lasting protection: Multiple active ingredients are formulated to keep working for up to 14 days, reducing the need for frequent reapplication under normal conditions.
• Quick knockdown: The spray delivers fast reduction of biting and nuisance flies plus gnats and mosquitoes, so horses feel relief soon after application.
• Broad insect control: Lice and deer ticks are also targeted, helping reduce exposure to pests that can transmit disease.
• Water-based, non-greasy formula: The carrier avoids a heavy residue and helps the product remain effective even when a horse becomes sweaty from work.
• Coat conditioning: Built-in conditioners leave a healthy shine and help maintain coat appearance while repelling insects.
• Economical refill size: The 128 oz easy-pour gallon refill saves money for multi-horse owners and busy barns.

Who It's For

Farnam Tri-Tec 14 is best for horse owners who need extended insect protection between applications and value a product that conditions the coat. It suits stabled horses, trail horses that see regular exposure to biting flies, and barns managing multiple animals where the 128 oz refill reduces per-use cost.

Owners who prefer daily light misting or those who need an immediate ready-to-use spray in a small bottle might look elsewhere, or pair the gallon refill with the 15 oz finishing spray or 32 oz ready-to-use option for convenience when away from the barn.
