Flea-quently Asked Questions

For: Fleas

Can fleas harm my pet?

Flea bites can cause pets to feel itchy so they will start to scratch and this can make their skin sore. Some animals develop an allergy to flea saliva called Flea Allergic Dermatitis and this can make them really uncomfortable and cause other health problems. In small dogs, puppies, kittens and older or sick animals a severe infestation can cause anaemia which can occasionally be fatal. Fleas also spread tapeworms, another parasite which can infect your pet skin.

How does Flerm’s Flea Combo treatment work?

Once applied, our Flea Combo treatment is stored in the sebaceous glands in your pet’s skin and spreads over the whole body surface with their natural oils. The treatment does not enter your pets bloodstream. Fleas and ticks are killed through contact with your pet’s skin and coat so they do not need to bite to be killed.

Is your Flea Combo treatment safe to use?

Yes. Our Flea Combo treatment uses tried and tested active ingredients (Fipronil and S-Methoprene) that have been used by vets for over 15 years to reliably kill fleas, ticks, larvae and eggs. The active ingredients we use are the same as those found in most other market leading (and more expensive) treatments that are available. See how our flea treatment compares to other market leaders here.

Is Flerm’s Flea Combo treatment safe to use if I have children?

As with all licensed veterinary medicines, our Flea Combo treatment has undergone extensive safety tests. When used as directed, pets treated with our Flea Combo treatment do not pose a health risk to children or adults. It is a recommended precaution that children or adults do not cuddle, handle or sleep with treated animals until the application site is dry.

Why might I see more fleas on my pet after applying Flerm’s Flea Combo treatment?

Our Flea Combo treatment 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 more fleas after treatment, it could actually be a sign that the product is working! If you have any concerns, you should contact your vet.

Why might I see a tick on my treated pet?

Most tick treatments such as our Flea Combo treatment are not tick repellents therefore individual ticks may still attach to your pet. After treatment with our Flea Combo treatment 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 vet.

Why might I see fleas on my pet after I’ve treated them?

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.

Why is it important to tackle flea eggs as well as fleas?

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. Our Flea Combo treatment not only kills fleas, ticks and lice on your pet, but also prevents flea eggs from hatching and infesting the home.

Do I still need to treat my pet even in the colder months?

Yes, absolutely. Although the likelihood of your pets being affected by fleas decreases in the winter months, the shift in climate change has resulted in us experiencing milder winters in the UK, favouring the survival of fleas outdoors for much longer. Fleas also continue to develop indoors in homes thanks to central heating. Therefore, it’s important to keep protecting your pet throughout the year.

Can I use your Flea Combo treatment on any breed of cat or dog?

Yes, our Flea Combo treatment 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.

What is the best way to get rid of a flea infestation in my home?

Flea infestations are unpleasant for you and your pets, and can take 3 months or more to resolve, so be patient.

Firstly, you need to make sure that all pets in the household have been treated every month with a suitable flea product that kills fleas, larvae and eggs. It is important to allow your treated dog or cat free access around the home otherwise any newly emerging fleas are likely to bite you instead! Good hygiene is also important, therefore thoroughly wash your pet’s bedding at at least 60C. You will also need to vacuum carpets and furniture on a regular basis, particularly dark areas where flea larvae love to migrate. Using a suitable household flea spray can also help speed up the process but unfortunately there is no immediate fix and it will take some time for all the flea life stages in the environment to die out.

What happens if my pet gets wet straight after applying Flerm’s Flea Combo treatment?

Once our Flea Combo treatment 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 vet for advice.

How soon can I stroke or handle my pet after applying the Flea Combo treatment?

You can cuddle, stroke and handle 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.

Do I need still need to treat my pet even if they don’t go outside much?

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

Can I use your Flea Combo treatment on pets other than cats or dogs?

No. At flerm we only sell flea and worming treatments to be used on cats and dogs. For any other type of pet please consult your vet.

For: Worms

How Does My Dog Get Worms?

There are 4 common ways your 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.)
4. From the mother to her puppies, either across the placenta before they are born, or via her milk when nursing

How Do I know When To Deworm My Dog?

You shouldn’t wait until you start seeing signs of worms as infections 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 scooting 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 dog’s stool or around their bottom.

How Often Should I Deworm My Dog?

It’s important that you don’t wait to see signs of worms or ill health before you worm your dog, and regular worming is part of responsible dog ownership to protect your pet, yourself and others. But how often you should worm will depend on a number of different factors. Experts recommend treating dogs for intestinal worms at least four times a year. However, more frequent treatment may be required in certain cases, for example if you have children, if there are pregnant women, elderly or immunosuppressed individuals in the home or if your dog has had fleas. Always follow the advice of your pet healthcare professional who can recommend the adequate frequency for your dog’s circumstances.

Why I should I cancel my Health Package with my vet to join Flerm?

Most vets will sell you a health package ranging in price from £13 to £20 per month, depending on the size of your pet. Unfortunately, they don’t usually send you reminders about when the flea and worm treatment is due, so it will be your responsibility to remember, order the treatments, and then travel to your vets to collect them each month.
With Flerm, we do all the remembering for you- we’ll send you each treatment at the exact time your pet needs it. Delivery is free, and our mailing boxes fit through most standard letterboxes. No need to be home to receive the parcel.
