Horse fly spray reviews: You should be more cautious when choosing fly spraying if your horse has health problems, open wounds, or simply sensitive skin. Consult always with a veterinarian for any concerns or adverse reactions. A new spray should first be tested for your horse on a small skin patch.
Some fly sprays are water-based, while others are oil-based. Both bases have their own set of advantages and disadvantages. Sprays with an oil base appear to work faster because the oil suffocates or drowns insects. Although it adheres well to the coat, it can also attract dust, so regular grooming may be required to keep your horse’s coat gleaming.
It is critical to check the number of ingredients used in the fly spray. Some brands contain a higher concentration of active ingredients than others. Those with a higher amount are more likely to be effective (but can also be more expensive). You sometimes get what you pay for!
