Fleas are practically everywhere, which means tapeworms are too.

  • Fleas can carry tapeworms. You’ll find fleas in the grass your pets rolls around on and in your pet’s fur, which they lick when they groom themselves. Rodents carry tapeworms, too, which can infect your pet if they ingest infected rodent tissue, like when cats eat mice.

    If you see signs of tapeworms, Bayer’s Tapeworm Dewormer for Dogs and Tapeworm Dewormer for Cats are safe and effective over-the-counter options for removing tapeworms from your dogs and cats at home.
