Thank you all! I currently use Pyranha although I'm always open to new things to try to see what works best(:
Nettex deet based ones are great
I make my own, you can just look up a simple recepie online and play with it until you get the perfect natural match💕
Pyranha brand fly spray is best. It works on any horse, makes their coat shiny, and stays on longer since it is an oil based fly spray. It repels very well and I've been using it for years
Phaser fly spray works and we also use benzo benzoate.
I just tried the equisect brand and it seems to work well!
