  • Treats biting lice on dogs.
  • Treats flea infestation on pet rabbits.
  • Fleas are eliminated within one day after treatment.
  • Protects dogs from further flea infestation for up to four weeks.

How Advantage Works

Advantage is a flea treatment that not only prevents and treats flea infestations but also helps prevent your home from becoming infested with fleas. It has an environmental larvicidal effect, controlling the flea lifecycle in your pet's surroundings wherever your treated pet goes.


Usage Instructions

  • Repeat treatment after four weeks.
  • Avoid treating more frequently than once a week, even if re-treatment is necessary.
  • New fleas in the environment may continue to emerge for up to six weeks after treatment, so multiple treatments may be needed.
  • It's recommended to use an environmental treatment against adult fleas and developing stages to reduce environmental flea challenges.
  • Treat all cats, dogs, and rabbits in the household to further reduce environmental challenges.
  • The product remains effective if the animal becomes wet (e.g., from rain or swimming).

Special Considerations

  • Treating a nursing bitch or queen with Advantage protects the entire litter against fleas.
  • Suitable for puppies and kittens from 8 weeks of age.
  • Suitable for young rabbits from the age of 10 weeks.


Advantage comes in a pack of 4 pipettes.
