FRONTLINE Plus and preventing fleas




Step 1
Use FRONTLINE Plus regularly to kill adult fleas on your pet.
Treat cats every 6 weeks and dogs every 2 months.

Step 2
Make sure all cats and dogs are treated.
Each pet in your household can act as a host for a flea infestation.
Step 3
Regularly vacuum your carpets and furnishings and wash your pets bedding above 60°C.
This will help to reduce the number of any eggs, larvae and pupae in the environment.




It’s normal to see a few new fleas on your pet even if they have been treated with FRONTLINE Plus. FRONTLINE Plus does not repel fleas so if the pet visits an infested environment, a few new adult fleas may jump onto them. These new fleas will be killed within 24 hours.
