Fleas rise to the top of your pet’s coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.
Active Ingredients: Flumethrin 4.5%, Imidacloprid 10.0%.
Use only one collar per animal. Fit collar around your pet’s neck, allowing for 2 fingers to fit between the collar and your pet’s neck to ensure a comfortable, yet snug, fit. Once collar is properly fitted, cut off any excess collar measuring 1″ or longer. The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing. Keep the collar in the bag and in the outer packaging until use. Replace the collar after 8 months for optimal tick and flea protection.
Water Resistance: It is unnecessary to remove the collar before immersing your pet in water. Seresto remains effective following a shampoo treatment, swimming or exposure to rain or sunlight. In order to maintain an 8 month duration, pets must not be bathed more than once a month. For pets that swim once a month or more, the control duration is reduced to five months for fleas and seven months for ticks.
