Go away, I'm reading
Best thing is Neem Oil, keeps the blighters away.
Mix 5ml Neem with 5 ml soap and mix up with 1 L if hot water and sponge that all over the horses. You see the horse flies zoom in, stop mid flight and go away.
The best thing to stop the itch if you get bitten is NAF fly gel. Takes the sting away and it stays away.
Neem also alleviates itching
What type of soap?
