Getting to know parasites

There are all kinds of jumping, slithering, crawling and flying parasites out there that can‘t wait to get acquainted with your beloved pet. Whether it’s worms, fleas, ticks, lice or mosquitoes, get to know your pet parasites before they get to know your pet.

Fleas

How do cat flea collars work?

Fleas are unfortunately a fairly common problem for cats and their owners. It doesn't matter where you live, how often your cats go outside, or even how often you vacuum; fleas are annoyingly skilled at finding a way to make your life miserable – usually at the worst possible time.

Luckily, there are plenty of cat flea treatment options available to make sure you don’t have to deal with cat fleas. Drops, tablets and sprays all look reassuringly like they’re actually doing something, but flea collars just look pretty much like normal collars. They might be easier to put on than other treatments – and they might last longer – but how do you know they’re actually working?

Firstly, not all cat flea collars are the same. Seresto is an advanced modern collar which has been built using cutting-edge technologies that enable storage of the active ingredients inside the collar which can work over longer periods – killing both fleas and ticks for eight months at a time.

The Seresto cat flea collar contains imidacloprid (which kills adult fleas and flea larvae) and flumethrin (which repels and kills adult and immature stages of ticks). Both ingredients work together through simple contact to kill fleas and ticks – which means the parasites don’t have to bite your cat before they’re affected. The Seresto collar works by gradually releasing a low dose of its active ingredients, to keep your cat protected at all times. This release starts once the collar comes into contact with your cat’s skin or coat and as the active ingredients diffuse into the skin's natural lipid layer, killing fleas on cats within 24 hours and preventing further infestation for 8 months.

The active ingredients are bound into the collar’s fine polymer matrix. This matrix ensures that controlled doses of imidacloprid and flumethrin are slowly released as and when your cat needs them, a much-needed improvement from older flea collars. Because the collar is odourless, you might not see or smell it working, but Seresto remains effective for eight months at a time.

Safety-closure mechanism for cat flea treatment and prevention

Cats are adventurous and agile creatures; they like to jump over fences and climb through small spaces when they’re exploring. So it’s important to get a collar that isn’t going to get snagged on anything. Seresto is equipped with a safety-release mechanism to prevent accidental injuries for these little adventurers. Seresto has a closing mechanism that opens with a hard tug (and a pre-determined breaking point for any serious struggles) so you don’t have to worry about your pet getting stuck.

So in fact, if you buy the right cat flea collar, you won’t have to think about cat flea treatments or prevention for months. No fleas, no worries, no top-ups.

Dog flea collars make your life that much easier

With so many different flea treatments for dogs available, why are collars so popular? 

If you’ve got a dog, fleas are probably a constant worry. You regularly pick through his coat, you check your comb under a magnifying glass and you sometimes start to imagine every bit of stray black fluff is suddenly going to start jumping. 

The fact is if you do find a flea, you know you’ve got a problem. Not only will it mean that you’ve got to spend the next few weeks constantly vacuuming, and washing everything in the house, but there’s also a risk that your dog will get flea tapeworms, flea allergy dermatitis or a secondary infection after scratching at bites.

If you’re a new dog owner, you’ll probably go to the pet shop and come away armed with every spray, tablet and dropper you can find. There are plenty of options around if you’re after flea treatments for dogs.

Types of flea treatments for your dog

However, these readily available tablets and sprays may not always be the best solution for keeping your pets safe from fleas. Treatments which are given by mouth to your dog require fleas to bite before they are affected, and sprays can be challenging as they need to be applied over the whole animal, wetting the coat.

Spot-on drops are a great way of keeping your dog protected against parasites – especially if you choose a brand like Advantage that kills fleas through contact. But much like tablets and sprays, you do need to remember to top them up regularly – usually every four weeks.

Seresto is a modern flea collar which offers the advantages of a spot-on without the need for top-up treatment – remaining effective for 8 months.

The Seresto flea collar for dogs kills fleas and ticks through simple contact for eight months. It’s water-resistant, odourless and looks just like a normal collar. Built using an innovative technology that slowly releases controlled doses of two different active ingredients, Seresto makes sure your dog stays protected.

How does the Seresto flea collar work?

Seresto flea and tick collars work by gradually releasing a low dose of its active ingredients (imidacloprid and flumethrin), keeping your dog protected at all times. This release starts once the collar comes into contact with your dog’s skin or coat and as the active ingredients diffuse into the skin's natural lipid layer, killing fleas on dogs within 24 hours and preventing further infestation for 8 months.

Why Seresto?

There are plenty of other flea collars around, but none work quite like Seresto. Unlike other collars, Seresto kills fleas and repels and kills ticks through simple contact, which means the fleas and ticks don’t have to bite your pet before they’re affected. Seresto is an easy to put on and fuss-free treatment that offers protection that lasts for eight months, meaning there’s no need to remember any regular top-ups. The collar doesn’t smell (unlike flea collars in the past) and is water-resistant, offering protection against not only fleas, but also ticks for your pet, and peace of mind for you.

Ticks

Why does your cat need a tick collar?

Tick treatment for cats is something many pet owners often choose to ignore, but that doesn't mean it should be forgotten about.

If you’ve got a cat, you’ve probably got one day set aside each month to check up with your cat’s medications, re-apply spot-on flea treatments and administer worming treatments to make sure your pet stays pest-free. But it’s easy to forget about the other parasite that your cat can pick up. This is where tick treatments for cats come into play.

While not all areas in New Zealand are affected, ticks do occur in much of the country - including all of the North Island, Marlborough and Nelson districts.  

Ticks are not just unsightly little parasites, they can also cause nasty infections if removed with their heads still embedded. A tick will sink its mouthparts deep into the skin of your cat and remain firmly attached until it’s swollen with blood. Tick bites can become inflamed and painful areas.

There are few effective tick treatments for cats that stop the parasites from causing problems. One of the easiest is a tick collar that also deals with fleas at the same time.

Seresto cat flea and tick collar looks just like a regular cat collar, but is built using an innovative technology that releases controlled doses of active ingredients that work against fleas and ticks through simple contact. This means that parasites don't need to bite and feed on your cat's blood in order to be exposed to the active ingredients. Ticks will still climb onto your cat’s coat but the repellent effect of Seresto prevents them from feeding. After coming in contact with your cat’s fur, the ticks will usually die and drop off.

Because of the way the collar slowly releases its active ingredients, Seresto will keep your cat protected from fleas and ticks for eight months at a time – which means no more circling every page of the calendar, and even fewer reasons to worry about ticks.

Why does your dog need a tick collar?

Find out why tick prevention for dogs is so important – and why a dog tick collar is one of the best options around.

Ticks are not just unsightly little parasites, they can also cause nasty infections if removed with their heads still embedded. While not all areas in New Zealand are affected by ticks, you can find ticks in much of the country - including all of the North Island, Marlborough and Nelson districts. A casual run through the long grass, especially in rural areas, can result in one or more of these arachnids attaching and feeding on your dog, so it’s important to make sure you’ve given your canine companion the best protection possible.

These parasites often live in long grasses in rural areas, grabbing onto the coat of passing animals as they brush through the grass. After finding the right spot to bite, they can stay attached to their victim for days. 

Why use a dog tick collar?

There are several different ways of combating ticks, but Seresto flea and tick collars are one of the best choices for several reasons. Because the collars remain effective for so long, you don't need to worry about treating your pet frequently. Seresto is also water-resistant and odourless, which means you can put it on and be assured in the knowledge that you've done your best to prevent your dog from coming home with any nasty surprises (aside from the usual burrs, twigs and mud, stuck in his fur of course…).

How does the Seresto collar for dogs work?

Seresto flea and tick collars contain two active ingredients (imidacloprid and flumethrin). The collar continuously releases a controlled dose of both, remaining effective for eight months. Unlike other treatments that work by releasing their active ingredient into your dog’s blood, the ingredients in Seresto are distributed externally, killing and repelling ticks through simple contact – which means ticks don’t have to bite your dog to be affected. In fact, Seresto actually repels ticks, as their feet become sensitive to your dog’s coat and will choose to drop off rather than stay and bite.
