The sun is there as well as a slight breeze. You arrive at the farm and want to go riding, but as well you as your horse get attacked by ... the flies. How to deal with those little disturbing insects. Although they don't man you any harm, you'd rather have them not around ... Fly spray is not helping very much. When you work your horse it will sweat and the fly spray will fade away. Therefore don't go and buy the cheapest bottle you can find and spray your horse every five minutes around the clock. It is a waste of your precious time and money. Even more fly-sprays can bring harm to you and your environment! Of course you could go all-natural with apple cider vinegar in the water troughs. But think about the impaction colic your horse might get from not drinking for three days. You might invest in fly masks, sheets and leg wraps. But believe us when we say those masks won't live very long ... Easiest is dreaming of the wintere wen flies magically disappear or just accept the fact have to live with them. If you’re going to have horses, you’re going to have flies.
