The flies where I ride are literally feasting on my horse. I took him out for a 10 minute walk and trot yesterday and he came in with fly bites all over his shoulders - and these are from stable flies!
Even at a trot, the flies were swarming us.
I have sprayed him with various commercial sprays. We have stable flies, horse flies and deer flies, as well as mosquitoes, as we back onto a regional forest.
Does anyone have any effective suggestions for protecting him while I ride? My only solution seems to be riding inside and I hate to do that.
