Advecta II contains the same active ingredients as Bayer Advantage II*. Advecta II is a fast-acting, fragrance free, waterproof, and easy-to-use solution. When applied monthly, Advecta II will kill fleas, flea eggs, and flea larvae for up to 4 weeks.

Pre-existing pupae in the environment may continue to emerge for 6 weeks or longer depending on climatic conditions.

Why are there still fleas on my pet after applying Advecta II?

As fleas die, they rise to the top of your pet’s coat. This is a good indicator that the product is working.

Why do I still have fleas in my home after applying Advecta II?

While fleas do lay eggs on your pet, it is common for the eggs to fall off of the animal and into the carpet, pet’s bedding, carpeting, beneath cushions on furniture, and any other areas your pet sleeps or has access. It is important to treat those areas by heavy vacuuming (seal and throw away bags) and washing bedding in hot water. Flea traps, sprays, and cedar chips (fleas hate the smell) are other options. If you do not treat your pet’s environment, you will miss more than 90% of the developing flea population (eggs, larvae and pupae).
