The Best Flea Treatment to Protect Your Dog and Cat This Spring in New Zealand
Spring in New Zealand means longer days, blooming gardens… and unfortunately, the return of fleas. As temperatures rise, flea eggs and larvae that have been lying dormant over winter start to hatch — leading to an explosion in flea activity.
If you’ve got a dog or cat (or both), now’s the time to get ahead of the problem before it becomes a full-blown infestation.
Why Fleas Are Worse in Spring
Fleas thrive in warm, humid environments — exactly what our Kiwi spring brings. Once a single flea finds your pet, it can lay up to 50 eggs per day. Those eggs fall off into carpets, bedding, and furniture, waiting to hatch. That’s why it’s so important to use preventive flea treatments before you start seeing fleas.
What to Look For in a Good Flea Treatment
Not all flea products are created equal. Here’s what matters most when choosing one:
-
Fast-acting: Kills fleas before they lay eggs.
-
Long-lasting: Protects for at least a month between doses.
-
Waterproof: Keeps working even after swimming or bathing.
-
Broad-spectrum: Ideally protects against ticks and worms too.
Choosing a product that covers all these bases saves you time, effort, and money.
