Once applied, FRONTLINE® Spot On is stored in the sebaceous glands in your pet's skin and spreads over the whole body surface with their natural oils. Fleas and ticks are killed through contact with your pet's skin and coat so they do not need to bite to be killed.

Yes, FRONTLINE® Spot On can be used on any breed of cat and dog, including collies and other herding-breed dogs which can sometimes show a sensitivity to some parasite treatments.

You must only ever use products on pet species that they have been specifically developed and licensed for. FRONTLINE® Spot On Cat can only be used on cats and FRONTLINE Spot On Dog can only be used on dogs. Do not use on rabbits.

As with all licensed veterinary medicines, FRONTLINE® Spot On has undergone extensive safety evaluation. When used as directed, pets treated with FRONTLINE® flea and tick treatments do not pose a health risk to children or adults. It is a recommended precaution that children or adults do not pet, play or sleep with treated animals until the application site is dry.

You can handle, stroke and cuddle your pet as usual as soon as the application site is dry. In the meantime treated animals should not be handled and children should not be allowed to play or sleep with them.

Flea infestations are unpleasant for you and your pets, and can take 3 months or more to resolve, so be patient. Follow our 5 steps to help resolve the problem:

• Ensure all cats, dogs and flea-bearing pets in your home are continually treated with an appropriate product at the recommended intervals for at least 3 consecutive months.
• Vacuum more often than usual – ideally daily - and include places your pet regularly visits, for example the car. The vibration caused by vacuuming helps to encourage pupae to hatch.
• Regularly wash your pet's bedding at a minimum of 60°C.
• Treat your home with a household flea spray containing an insect growth regulator (IGR), such as FRONTLINE HomeGard. Always read the instructions on the can before use.
• Ensure your pets have access to all the same parts of the home that they usually do. Fleas present in those areas will be killed when they hop onto your treated pet.

Once FRONTLINE® Spot On has been applied it is recommended to keep your pet out of the rain and away from watercourses for the next 48 hours. If they do come into contact with rain within this period, it is unlikely that your pet would have been wet enough for the product to be washed away. However, if your pet gets soaked to the skin then the efficacy of the treatment may be impaired and reapplication may be warranted. If this is the case, please contact your veterinarian for advice.

If you can still see fleas on your pet after treating them, it would be natural to think that the treatment isn’t working. However, no product can repel fleas from jumping onto your pet so it is normal to continue to see fleas after treatment as your pet can pick up new fleas from the environment at any time. Moreover, if you are fighting a home infestation, it is highly likely that you will see fleas on your pet for 3 months or more as it can take this long to get rid of the infestation. Don't worry, if you see fleas for several days in a row, today's flea is not the one you saw yesterday. Your treated pet is a flea-killing machine and any fleas jumping on will be killed within 24 hours. If you have any concerns, please your veterinarian.

Most tick treatments such as FRONTLINE® Spot On are not tick repellents therefore individual ticks may still attach to your pet. After treatment with FRONTLINE® Spot On ticks will be killed within 48 hours after exposure, before they are fully fed, thus helping to reduce the risk of disease transmission. If you have any concerns, please contact your veterinarian.
