This simple but effective recipe combines the power of a few simple ingredients. This combination repels flies quickly, as they don't like any of the components. You can mix this concoction and pour it into a spray bottle to spray on it at your leisure.
Do not use this fly spray on pregnant horses. Only use therapeutic-grade essential oils. Essential oils are safe to use topically on most horses, but some horses may react to essential oils. Do a patch test test prior to using. If your horse is nursing, receiving other medication, or is unwell, speak to your veterinarian before using this formula.
