Buying advice

When choosing a fly and mosquito control product for horses, consider the severity of the pest pressure, the horse’s sensitivity to chemicals, and how often you can re-apply. EPA-registered concentrates like FlyAway provide long-lasting protection but may have a strong odor, while natural sprays are gentler but need more frequent application. For barns with many horses, bulk concentrates or spray systems can be more economical, whereas single-horse solutions such as sprays or repellent blankets are convenient for smaller operations.
