The horse shies away from the spritzer bottle, won't tolerate fly products on its face, or breaks out in a rash from the repellents. Regardless of whether your horse is troublesome or trouble-free when it comes to fly control, there are basic do's and don'ts that every horse handler should follow in order to keep a cooperative horse cooperating, to gain the agreeableness of a difficult horse, and to maintain maximum safety for horse and handler. Begin the fly control program when you start seeing flies in the spring, and continue until the flies are finished for the season. It's a matter of personal preference and what you find easiest for your horse. Powders and dips are not very popular.
Powders are messy, can drift into the eyes and nose, and can be shaken or rolled off.
Dips are pretty inconvenient to use on a regular basis, at least for standard-sized horses and ponies. Unless you have an equine-sized pool or tub that you can run a horse or a number of horses through, you'll have to mix the dip in buckets of water and pour it on the horse. Strips that can be braided into the tail are handy for broodmares or other pastured horses that aren't going to be sprayed every day, notes Linda Thompson, DVM, equine ambulatory section, Iowa State University. Tags can be braided into the mane, but tend to be fairly heavy for the tail. Usually they are only used on horses that are out all of the time.
