COMMON QUESTIONS

Yes. Even indoor-only pets can become exposed to fleas if an untreated pet visits your home or if you or a friend brings in flea eggs or cocoons on shoes or clothing.

Most tick treatments such as FRONTLINE Plus® and FRONTLINE® Spot On are not tick repellents therefore individual ticks may still attach to your pet. After treatment with FRONTLINE Plus® / 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. FRONTLINE Tri-Act® FOR DOGS is a tick repellent which means ticks will climb onto your dog and then quickly climb off due to the exposure to the product. You may see some ticks on your treated dog during this time, or during the 6 hours it takes for the product to kill ticks. If you have any concerns, please contact our technical services team at petsUK@boehringer-ingelheim.com, or your veterinary surgeon.

No, FRONTLINE Tri-Act® can only be used on dogs.

FRONTLINE Plus® / FRONTLINE Tri-Act® / FRONTLINE® Spot On kills fleas by affecting their nervous system, making them hyperactive before dying. These dying fleas often rise to the top of the pet's coat and bounce, so if you feel like you may be seeing fleas more after treatment, it could actually be a sign that the product is working! However, if you have any concerns, please contact our technical services team at petsUK@boehringer-ingelheim.com, or your veterinary surgeon.

Yes. Follow two simple precautions to keep your cats living with dogs treated with FRONTLINE Tri-Act® safe:

• Keep cats and treated dogs away from each other until the application site is dry
• Ensure that cats do not groom the site of application on a treated dog

Yes. FRONTLINE Plus® for extra large dogs can be used on dogs over 40 kg without an upper weight limit. To treat dogs over 60 kg with FRONTLINE Tri-Act®, use the appropriate combination of two pipette sizes that most closely matches the bodyweight. To treat dogs over 60 kg with FRONTLINE® Spot On, use two large size pipettes for dogs 20 to 40 kg.

The minimum time to wait between two treatments of FRONTLINE HomeGard® is 6 months. It is not necessary to use FRONTLINE HomeGard® repeatedly, if you are regularly treating your cat or dog with an effective flea and tick treatment such as FRONTLINE® spot-on products. In most cases one treatment of FRONTLINE HomeGard® is enough to see you through until the end of the infestation.

Yes, FRONTLINE Plus® / 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.

If used as directed in the usage instructions, FRONTLINE HomeGard® does not pose a health risk to children or adults. It is a recommended precaution that you treat one room at a time and avoid the area for at least 1 hour or until the area is dry, and then allow the area to air.

It often takes 3 months or more to get rid of a flea infestation in the home, because it can take this long for all immature fleas in their protective cocoons to develop and emerge as new fleas before they can be killed.

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:

1. 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.
2. 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.
3. Regularly wash your pet's bedding at a minimum of 60°C.
4. 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.
5. 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.

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 with FRONTLINE Plus® and FRONTLINE® Spot On, or within 6 hours with FRONTLINE Tri-Act®. If you have any concerns, please contact our technical services team at petsUK@boehringer-ingelheim.com, or your veterinary surgeon.

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.

As with all licensed veterinary medicines, FRONTLINE Plus®, FRONTLINE Tri-Act® and FRONTLINE® Spot On have 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.

Both products kill fleas and ticks on your pet, however our most advanced formula FRONTLINE Plus also stops flea eggs from hatching and infesting your home.

There are no known health risks associated with applying FRONTLINE Plus or FRONTLINE Spot On to your pet during pregnancy. As a general rule it is good practice to avoid direct contact with any chemicals during pregnancy.

Even if you have treated your pet for fleas, some fleas may still have time to lay eggs before dying. These eggs can develop into new fleas in as little as 14 days, therefore it is important to tackle flea eggs too. Most flea products only kill fleas on your pet. FRONTLINE Plus® not only kills fleas and ticks on your pet, but also prevents flea eggs from hatching and infesting the home. FRONTLINE Tri-Act® FOR DOGS kills fleas in 6 hours, before they have time to lay eggs - resolving the flea egg problem altogether!

Once applied, FRONTLINE Plus® / FRONTLINE Tri-Act® / 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.

No, in fact no product stops fleas from jumping onto pets. However, fleas are killed after contact with your treated pet: within 24 hours for FRONTLINE Plus® and FRONTLINE® Spot On and within 6 hours for FRONTLINE Tri-Act®.

No, FRONTLINE Plus®, FRONTLINE Tri-Act® and FRONTLINE® Spot On act topically which means that fleas and ticks are killed through contact with your pet's skin and coat so they do not need to bite to be killed.

For the routine treatment of intestinal worms in your adult dog or cat use FRONTLINE^® WORMER every 3 months.

In certain circumstances, it may be advised to worm more frequently. Examples include higher-risk scenarios, such as if your pet lives with small children or an immunocompromised adult, or where your pet has frequent risk of infection. In these cases, or in case of suspected heavy roundworm infection, we recommend you contact your vet for further advice.

There are 4 common ways your cat or dog can pick up intestinal worms:
1. By swallowing infected fleas while grooming
2. By ingesting worm eggs from a contaminated environment (toys, grass, soil, etc.)
3. By eating or scavenging carcasses of other infected animals (mice, rabbits, birds, etc.) or by being fed an unprocessed raw food diet
4. From the mother to her kittens or puppies, either across the placenta before they are born (puppies only), or via her milk when nursing

You shouldn’t wait until you start seeing signs of worms, as infections often have to be quite severe before signs let you know there is a problem. Signs of worms can include weight loss, bloated tummy, diarrhoea, vomiting and rubbing their bottom along the ground, but these are not specific to worm infections. Worm eggs are microscopic, but you might see worms (looking like spaghetti) or worm segments (looking like grains of rice) in your pet's stool or around their bottom.

Yes. People can get infected by some worm eggs present on their pet's fur or in the environment, which can cause serious diseases. Roundworm larvae can travel through the body and cause blindness in severe cases, especially in children. That is why it’s important to worm your cat or dog regularly, even if you can’t see any worms or your pet looks healthy. Regular worming of your pet can help reduce the chance of this happening and help you protect your whole family.

No. Your pet can pick up worms at any time throughout the year. Worm eggs can survive in the environment for several years and potentially infect your pet anywhere they explore. Fleas, another potential source of worms, are also a risk year-round.
