Easy Application

Applying Tri-Tec 14 Fly Repellent is easy—simply brush your horse’s coat, shake the product well, and spray.

Can I use on a grown cat ?

Answer by ChewyMay 31, 2021
This product is intended for use with horses only. It should not be used on cats.

Why does the bottle not say sunscreen on front label? This is the only reason I buy this.

how long does it last

Answer by ChewySep 06, 2019
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 exposed to heavy rain.
