The next generation of fly spray is here! UltraShield(R) Gold offers Absorbine's most advanced fly protection with an innovative formula that works differently than traditional fly sprays - meet Absorbine FlyShield(R) . This formula includes tried and true ingredients but incorporates a combination of fatty acids that work together to create a wider forcefield of long lasting protection. As the bug enters the forcefield area, it gets highly disorientated and is unable to locate or land on your horse. UltraShield(R) Gold has been proven effective for over 100 different insects so you can be rest assured your horse will be comfortable even when the bugs are at their worst. | Absorbine UltraShield Gold Insecticide and Repellent Trigger Spray | Size 1 gal
