Year-round parasite protection
Fleas and worms are different parasites, and not every treatment covers both. Learn what may be missing from your pet's protection and how to help keep your pet, home and family covered throughout the year.
The fleas you see on your pet are only a small part of the problem. Adult fleas make up around 5% of a flea population. The other 95% exists as eggs, larvae and pupae hidden in carpets, pet bedding, floorboards, furniture and outdoor resting areas.
Fleas are most active in warm, humid conditions, but they do not simply disappear in winter. Cooler temperatures can slow their life cycle, while heated homes provide the warmth they need to keep developing. Flea pupae can also remain protected in the environment and emerge when conditions improve.
Stopping treatment over winter gives the flea life cycle an opportunity to continue. Consistent, year-round treatment helps kill adult fleas before they lay eggs and prevents the household flea population from building up.

Most fleas are hiding where you cannot see them. Treat your pet and their environment to help break the cycle.
Most combined flea and worm treatments do not cover tapeworm. This means your pet may still need separate tapeworm protection, even when their regular flea and worm treatment is up to date.
For adult cats and dogs, give a full-spectrum worming treatment every three months that specifically includes tapeworm, unless their current parasite treatment already includes tapeworm cover. Puppies and kittens need more frequent worming.

Here's what popular NZ treatments actually cover, based on their New Zealand label claims.
“Yes” means the label claims the product kills, treats or controls that parasite. Prevention-only claims are not counted. “No” means there is no treatment claim.

No flea, tick or combined product in this table treats tapeworm in dogs. If your dog is on one of these, they may also need a dedicated wormer or a tapeworm treatment.

NexGard Spectra is the only combined product in this table with a tapeworm claim for cats. On any other flea product, your cat may also need a dedicated wormer for tapeworm.
Parasite control matters for people too. Roundworm eggs passed in pet poo can contaminate soil, and people can accidentally swallow microscopic eggs after contact with contaminated ground. Young children are particularly vulnerable because they often play close to the ground and put their hands near their mouths.
Regular treatment, prompt poo collection and good hand hygiene help protect your pet, your home and your family.

Your pet's treatment schedule will depend on their age, lifestyle and level of risk. The following is a common guide.
Every two weeks from 2 to 12 weeks of age: 2, 4, 6, 8, 10 and 12 weeks
Monthly from 12 weeks to 6 months
Every three months after 6 months for a typical-risk adult
The short answer: as often as your product's label says, all year round. Re-treatment intervals vary widely between products, so the pack is always your guide.
Many spot-ons, chews and tablets are designed to be given every month. Set a repeating reminder, or use Autodeliver so the next dose arrives when it's due.
Some chews and spot-ons protect for up to three months from a single dose. Fewer doses to remember, but the re-treatment date still matters just as much.
Collars can protect for several months at a time. Check the label for the replacement date and note it somewhere you'll actually see it.
We get that it's easy to skip a dose when you can't see a single flea. But adult fleas on your pet are only a small part of the picture. Most of the flea lifecycle is happening as eggs, larvae and pupae in your carpet, bedding and furniture.
Treat every cat and dog in the household with an appropriate product and continue treatment at the label interval. Missing one pet can allow the flea life cycle to continue.
Wash pet bedding regularly, vacuum carpets and furniture, and clean the places where pets sleep and rest. Dispose of vacuum contents promptly.
Be consistent. Because immature flea stages can remain protected in the environment, it may take several months of consistent treatment and cleaning to fully break an established flea life cycle.
Check what your current treatment covers and make sure your pet is protected for their age, lifestyle and risk level. If one product does not provide all the cover they need, an additional worm treatment may be required.
Not always. Some products treat fleas only, while others cover fleas and selected worm species. Always check the label for the individual parasites included.
Not necessarily. Tapeworm is a common gap, so look for a specific tapeworm claim rather than assuming it is included.
Flea development may slow in cooler conditions, but the life cycle can continue throughout winter, particularly inside heated homes. Year-round treatment helps prevent the population from rebuilding.
New adult fleas may continue emerging from eggs, larvae and pupae already in the environment. Keep every pet treated at the correct interval and continue cleaning their bedding and resting areas. It can take several months to break an established life cycle.
Every three months is a common guide for typical-risk adult pets. Pets that hunt, scavenge, eat raw meat or have other higher-risk lifestyles may need more frequent treatment. Ask your veterinarian for an individual recommendation.
No. Use only a product labelled for your pet's species, age and weight. Some dog flea treatments can be highly toxic to cats.
