We moved yards in January, I'm not sure if it's the difference in yard, or just the flys are in early/ badly this yea, but they're really bugging her (no pun intended). last summer was spent mainly on box rest so we only used a minimal amount of Naff spray & a little tag on her head collar.
Loads of people use home brewed sprays at our yard, and lots have fly rugs.
Which brands do you find work? And the same with fly rugs?
