Fights Against Fleas at All Stages of Development
K9 Advantix II protects your pet against fleas at all stages of the parasite's development. K9 Advantix II breaks the flea life cycle by killing the living fleas on your dog before they can lay eggs. It also prevents the development of existing flea eggs, larvae, and pupae, helping to prevent future infestations.
K9 Advantix II also kills reinfesting fleas (newly hatched fleas jumping back on your dog) within two hours, and it prevents fleas on a treated dog from infesting your home. Effective Against Biting Flies and Lice
In addition to complete tick, flea, and mosquito protection, K9 Advantix II also repels painful biting flies from feeding on your dog, and it effectively kills up to 100 percent of lice within one week of treatment. Waterproof Formula
K9 Advantix II is waterproof, so there's no need to reapply after your dog has a bath or goes for a swim. Studies show that dogs are still protected against parasites after exposure to water, though for best results, dogs treated with K9 Advantix II should be bathed with a non-detergent shampoo.
