Cavalor Flyless is specially formulated to protect both horse and rider from pestering insects. The main active ingredient in this product is Icaridin (20.6%), which has been shown in studies to be more effective against mosquitoes than other repellents. Icaridin also does not kill insects, meaning they are less likely to develop a resistance to the product. Non-sticky, non-greasy, and with a pleasant scent, Flyless is gentle on skin and won’t stain clothes, making it the ideal choice for summer riding. Safe for dogs, too!
