How does Sentinel work?
Sentinel is used in the prevention, control, and treatment of various worm infections. Sentinel Flavor Tabs contain milbemycin oxime, which interferes with the worms nervous system, eliminating the immature stage of the heartworm larvae and the adult stage of hookworms, roundworms and whipworms. Sentinel also contains lufenuron, an insect development inhibitor, which breaks the flea life cycle by inhibiting flea egg development.
