Important Information
Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

How does FRONTLINE® Spray work?
FRONTLINE® Spray contains the active ingredient fipronil. Once applied, FRONTLINE® Spray kills fleas and ticks through direct contact.
How often do I need to use FRONTLINE® Spray?
FRONTLINE® Spray kills fleas, ticks, and chewing lice for at least 30 days.
Why might I see fleas and ticks on my cat or dog after treatment?
You are likely seeing new fleas and ticks. FRONTLINE® Spray is highly effective at killing fleas and ticks after they come in contact with the treated pet. If you are fighting a home flea infestation, it is highly likely that existing fleas will continue to emerge from the environment for 2-3 months or more, depending on environmental factors. Regular use of FRONTLINE® Spray will stop the infestation by killing these new fleas before they can reproduce.
Do I need to use other flea & tick treatments while using FRONTLINE® Spray?
No, FRONTLINE® Spray is an effective treatment against fleas and ticks that lasts for 30 days. Applied monthly, you do not need to use any other treatments while using FRONTLINE® Spray.
Do I need to treat my cat or dog for fleas and ticks even in colder months?
Yes, although the likelihood of your cat or dog being affected by fleas and ticks decreases in the winter months, they can still pose a threat to your pet. Therefore, it’s important to keep protecting your cat or dog throughout the year.
My cat or dog doesn’t go outside much, do I still need to treat them for fleas and ticks?
Yes, even ‘indoor-only’ cats or dogs can become exposed to fleas. Indoor-only dogs still spend time outdoors whether it be to go on a walk or just going to the bathroom outside. Your pet could also be exposed if an untreated cat or dog visits your home or if you or a friend brings in “hitchhiker” fleas on shoes or clothing.
Is FRONTLINE® Spray okay to use on my cat or dog?
FRONTLINE® Spray is approved for use for cats and dogs and puppies and kittens 8 weeks of age or older. If you believe your cat or dog has experienced any side effects after use of FRONTLINE® Spray, please contact your veterinarian or contact the Veterinary Technical Solutions Team at: 1-888-637-4251.
Can I handle or pet my cat or dog after applying FRONTLINE® Spray?
Allow product to completely dry before handling your pet.
What are the signs of fleas on my cat or dog?
Apart from seeing fleas on your cat or dog or in your home, other signs that your cat or dog might have fleas include increased itching, scratching, licking, nibbling and over-grooming. You may also see small dark red or black specks (flea dirt) on your cat or dog’s skin, bedding or on furniture.
How do cats or dogs pick up fleas?
Cats and dogs can pick up fleas from anywhere untreated pets and wildlife have been—indoors or outdoors. Fleas on these animals lay eggs, which fall off into the environment and develop into young adult fleas ready to jump onto your cat or dog.
Where can I find the expiration date for FRONTLINE® Spray, and how long will it last once I’ve bought it?
FRONTLINE® Spray has no expiration date.
What do I do if I did not see the answer to my question?

Nice to keep on hand
By Carine on May 6, 2022
I like having this for the times I need to treat something with fleas asap. Even though the label doesn't state it, you can put a small amount in spots down a puppy or kitten's back and rub throughout for fleas or mites when they are too young for other treatments.

Flea Spray
By Judy on Feb 27, 2022
Use to use this years ago until you could no longer get it from the vet. My sister and I used it and we Never hard fleas. It's cheaper then what the Vets want you to use. I'm on a fixed income and the price is good for me. Thank you for having this product.

Kills fleas for long time
By Ginger on Jan 24, 2022
I would only use this spray with the Frontline drops on the back of the dog you apply monthly and use this spray as needed. This spray really works and just a little spray keeps the fleas off of your dog. Chewy was the only one who had this spray available and for the cheapest price.

Effective repellent
By JJsmom on Jan 31, 2022
I use this to repel ticks before hikes and camping. You have to rub it in well and let it dry. It’s not a good alternative treatment to flea and tick medication. But it’s a nice supplement.

Works well
By Frej on Oct 25, 2021
I have used this for many years and find it always a good fall back if I don’t get rid of fleas early enough. After bringing some rescue kittens home I had been battling a small flea infestation, I needed to knock them out fast, as I have a dog that has pretty adverse skin reactions to fleas, and this seemed to remedy my problem
