Farnam Tri-Tec 14 Fly Spray 4

Expensive, but effective! Less expensive fly sprays don't seem to have the residual repellent effect that Tri Tec does. I've been a fan of the Equisect fly sprays for a long time, but I'm finding TriTec to be more effective now.

In the man vs. biting stable flies everlasting battle, this helps me to be a little better armed!
