Nexgard flea and tick treatment contains a powerful ingredient, afoxolaner. Afoxolaner induces hyperexcitation and thus uncontrolled activity of the central nervous system in insects and acarines, resulting in their death. Nexgard begins to kill fleas four hours after administration and kills fleas before they can lay eggs, thus preventing subsequent infestations. Effective against 5 different types of ticks, Nexgard is proven to prevent Lyme disease infections after black-legged tick infestations 28 days after treatment.
