Equine America Forget Flies Spray. Forget Flies Spray has a revolutionary silent spray applicator with a significantly reduced hiss which makes it the fly spray of choice for nervous or sensitive horses who resent conventional spray applicators.

These unique and consistent volatile compounds stimulate an adverse reaction in the sensory receptors of the flies and other ectoparasites and biting insects, providing natural summer support to the horse, without the need for harmful chemicals.

Forget Flies comes as a ready to use spray providing a powerful mist of long lasting, natural active ingredients and an attractive lemongrass aroma. Active
