Got Fleas? Your Essential NZ Guide to Spotting and Treating Fleas on Your Dog or Cat
If your cat is scratching like it’s auditioning for Riverdance or your dog seems unusually agitated, fleas might be the culprits. These tiny pests thrive in New Zealand’s temperate climate and can turn a cosy home into an itchy battleground. Whether you're in Auckland, Christchurch, or Invercargill, understanding how to identify, treat, and prevent fleas is key to keeping your pets and your home flea-free.
What Are Fleas and Why Should You Care?
Fleas are small, wingless parasites that survive by feeding on the blood of mammals—your pets included. A single female flea can lay up to 50 eggs per day, which quickly fall into your carpet, pet bedding, or garden, making reinfestation almost guaranteed without proper treatment.
In New Zealand, the most common offender is the cat flea (Ctenocephalides felis), but don’t be fooled by the name—this species loves both dogs and cats.
How to Spot Fleas on Your Pet
Early detection is key. Here are the signs to look out for:
-
Excessive scratching or grooming
-
Red, irritated skin or bald patches
-
Flea dirt (tiny black specks of flea faeces that turn red when wet)
-
Visible fleas jumping or crawling in the fur
-
Restlessness or behavioural changes
Use a fine-toothed flea comb, especially around the neck, tail base, and hind legs—hot zones for flea activity.
The Health Risks of Fleas
Left untreated, fleas can cause more than just itching:
-
Flea allergy dermatitis: A common allergic reaction to flea saliva
-
Tapeworms: Pets may ingest infected fleas while grooming
-
Anaemia: Particularly in kittens or puppies, a heavy flea load can cause dangerous blood loss
-
Skin infections: From persistent scratching
Best Flea Treatments in NZ for Dogs and Cats
Flea treatment options abound, but choosing the right one for your pet (and lifestyle) matters. Here are NZ’s most trusted solutions:
Spot-On Treatments
These are applied directly to the skin, usually monthly. Brands like Frontline Plus, Advantage, and Revolution are popular go-tos. Some also protect against worms and ticks.
Flea Collars
Great for long-term prevention. Products like Seresto collars offer up to 8 months of protection and are water-resistant.
Oral Flea Tablets
Fast-acting and convenient. Options like NexGard, Bravecto, or Capstar work from the inside out. Always dose based on weight.
Flea Shampoos and Sprays
Ideal for immediate relief or sensitive pets. These can be combined with longer-lasting solutions.
Environmental Control
A must-do step! Fleas lay eggs in your home, not just on your pet. Vacuum regularly, wash bedding on hot cycles, and consider flea bombs or sprays for serious infestations.
Natural Flea Remedies: Proceed With Caution
While essential oils and natural remedies sound appealing, many can be toxic to pets (especially cats). Always check with your vet before using products not specifically made for pets.
