FRONTLINE PLUS frequently asked questions


FRONTLINE PLUS and FRONTLINE SPRAY are simple to apply. Watch our videos or print out our easy-to-follow instructions to keep your pet free of fleas, ticks and worms.

How does FRONTLINE PLUS work?

It contains 2 active ingredients to break the flea life cycle at every stage. One ingredient kills the adult fleas on your pet. The other ingredient stops fertile eggs being laid and prevents larval and pupal development, preventing re-infestation of your pet and contamination of your home.

How often should I use FRONTLINE PLUS?

Treat all your dogs and cats every month. When applied correctly, FRONTLINE PLUS remains active on your pet’s skin for one month. If you are in a paralysis tick area, apply FRONTLINE PLUS every 2 weeks to provide paralysis tick control for your dog. If you are in a paralysis tick area and have a cat, apply FRONTLINE SPRAY every 3 weeks for protection against paralysis ticks.

Do I need to apply FRONTLINE PLUS or FRONTLINE SPRAY to all of my dogs and cat?

Yes, you must treat all dogs and cats with FRONTLINE PLUS to resolve flea infestations and prevent household contamination. If one pet is left untreated, fleas on that pet could deposit viable flea eggs into your home environment. These eggs will develop into adult fleas and re-infest your pets.

How long before and after bathing my pet should I apply FRONTLINE?

Ensure your pet is totally dry before applying FRONTLINE products. Do not bathe or shampoo your pet for at least 48 hours.

What shampoo is best for my pets when using FRONTLINE PLUS or FRONTLINE SPRAY?

Use a gentle, soap-free, pet shampoo. Don't use other insecticides (flea treatment such as flea wash), human shampoo, or anything that strips oils from your pet's coat or skin.

When should I start treating my pets with FRONTLINE PLUS?

It is safe to treat puppies and kittens with FRONTLINE SPRAY from 2 days of age. Puppies and kittens can be treated with FRONTLINE PLUS from 8 weeks of age.

Is FRONTLINE PLUS safe to use on pregnant and lactating pets?

Yes. FRONTLINE PLUS can be used on breeding, pregnant and lactating bitches and queens.

How often should I use FRONTLINE PLUS during the tick season?

FRONTLINE PLUS should be applied every 2 weeks for control of paralysis ticks on dogs, and every month for control of brown dog ticks. FRONTLINE SPRAY should be applied every 3 weeks for control of paralysis ticks on dogs and cats, and every month for control of brown dog ticks.

Is FRONTLINE PLUS water-fast?

Yes. FRONTLINE is water-fast. It is OK to bathe your pet before using FRONTLINE, but the coat should be completely dry prior to application. In the 48 hours immediately after treatment, do not bathe, shampoo or let your dog go swimming.

Should I reapply FRONTLINE PLUS if I see more fleas on my dog or cat soon after application?

No. FRONTLINE PLUS is effective for a whole month. If you see fleas on your pet, and it has been correctly treated with FRONTLINE, the fleas have probably recently emerged from your environment and will soon be killed by FRONTLINE on your treated pet. To reduce flea infestation in your environment, follow this advice for flea control for dogs and cats.

Is FRONTLINE a repellent?

No. FRONTLINE is a flea treatment that affects fleas when they are exposed to the active ingredient on your pet's coat. Unfortunately, there is no product on the market that effectively repels fleas or kills fleas instantly. Fleas have to jump onto treated pets to come in contact with the active ingredient regardless of which flea control product is used, and all products take a period of time to kill those fleas.

Can I share a single pipette between more than one dog or cat if I buy a larger size?

Never divide pipettes between your pets. Use the correct pipette size for each pet to ensure the best flea treatment for dogs and cats, and to guard against ticks on dogs . The FRONTLINE product selector will help you choose the correct pipette size for your pet.

Can I use the FRONTLINE PLUS FOR CATS on my dogs and FRONTLINE PLUS FOR DOGS on my cat? What about FRONTLINE SPRAY?

FRONTLINE PLUS for cats and FRONTLINE PLUS for dogs are not exactly the same. Use the appropriate product for your dog or cat. FRONTLINE SPRAY can be used on both dogs and cats.

My pet has licked the FRONTLINE PLUS or FRONTLINE SPRAY. Will it be OK?

If licking occurs shortly after application, a brief period of hyper-salivation may occur due to the taste.
Do not use FRONTLINE PLUS if you or your pet have known hypersensitivity to insecticides or alcohol.

Where is the best place to store my FRONTLINE PLUS or FRONTLINE SPRAY?

Store FRONTLINE products at room temperature, below 30°C, and always check the expiry date on the end panel of the pack before use. Do not store FRONTLINE PLUS or FRONTLINE SPRAY in the fridge.

I just applied FRONTLINE PLUS. How long until my pet's flea infestation is gone?

FRONTLINE PLUS is a flea treatment for dogs and cats that will spread over the coat of your pet within 24 hours and continue to be effective for one month. Any fleas that jump on to your treated pet will die within 12 to 24 hours. But adult fleas on your pet are only 5% of the total flea problem. The other 95% are the eggs, larvae and pupae in the environment waiting to hatch and jump on to your pets.

The best way to kill fleas is to break the flea life cycle. By applying a flea treatment such as FRONTLINE PLUS every month you will deplete the flea population over time and protect your home environment.

Can FRONTLINE PLUS or FRONTLINE SPRAY be used on pets other than cats or dogs?

No, FRONTLINE PLUS and FRONTLINE SPRAY should only be used on dogs and cats. Never use FRONTLINE on rabbits.
