Flysprays are very almost as annoying as flies. I use different kinds, all the time and none really work that well. Some things I've found helpful though are putting flystrips in your barn or stables? It doesn't really help when your horse(s) are in the pasture or out and about but it really does make a difference in and around your barn or stables.. Another thing that I've found helpful is a type of cream that you can rub in their ears and on their legs and back.. along with the spray. It's called SWAT Fly Ointment, and it works great for me and Pride. Hope I Helped! --Sydney
I buy the concentrate and mix my own solution. I don't dilute it nearly as much as you are supposed to, but my horse has never had any issue with the spray. It works as well as anything I've ever seen by far, and saves so much money!
