When Does Flea and Tick Season Start in Australia?
Share
Spring brings warmer afternoons, longer walks, and more outdoor time with your pet. Unfortunately, it can also lead to more fleas and ticks. These parasites love warm, humid weather, so spring and summer are especially hectic times for pet owners in Australia.
Flea and tick season doesn't start on the same date everywhere. Australia's climate is quite diverse, and in warmer areas, parasites can stay active all year round. Knowing the risks in your area can help you keep your dog or cat safe before parasites become a problem.
When Is Flea Season in Australia?
Fleas are often more active during spring and summer because warm, humid conditions help them develop faster. However, they can survive through winter on pets and inside heated homes.
Year-round flea protection may help prevent an infestation before scratching begins. By the time adult fleas appear, eggs and larvae may already be hiding in bedding, carpets, and furniture.
When Is Tick Season in Australia?
Tick activity varies by species, climate, and location. In many high-risk areas, paralysis ticks become more active from late winter through spring and summer, particularly during warm and humid weather.
Ticks may remain active throughout the year in warmer northern regions. Spring is a useful reminder to review your petβs protection, but prevention may be necessary year-round.
Which Parts of Australia Have the Highest Tick Risk?
Paralysis ticks are commonly found in humid coastal areas of Queensland, New South Wales and Victoria. Pets near bushland, long grass, or areas visited by native animals may face a higher risk, although ticks can also appear in suburban backyards.
Travelling to a coastal, bushy, or humid area may expose your pet to unfamiliar tick risks. Ask your veterinarian whether additional protection is needed before your trip.
How Can You Tell If Your Pet Has Fleas?
Frequent scratching is one of the most recognisable signs of fleas, but it is not the only one. Dogs and cats may also lick, chew or bite particular areas of their body.
Other possible signs include:
- Red or irritated skin
- Small scabs
- Thinning hair or bald patches
- Restlessness
- Tiny black specks in the coat
- Visible fleas moving through the fur
Those black specks could be flea dirt. Just put a few dots on some damp white paper to test them out. Flea dirt can leave a reddish-brown stain since itβs made up of digested blood.
Some pets can be really sensitive to flea bites and might get very irritated even after just a few. If your pet is scratching a lot, has damaged skin, or is losing hair, it's best to have a vet take a look.
What Are the Signs of a Paralysis Tick?
Paralysis ticks can seriously harm dogs and cats, and in some cases, they can be life-threatening. The symptoms might start off mild but can get worse as the toxin impacts your pet's nervous system.

Warning signs can include:
- Weakness or wobbliness in the back legs
- Difficulty standing or walking
- A change in the sound of a bark or meow
- Gagging, coughing or vomiting
- Unusual tiredness
- Loss of appetite
- Laboured or noisy breathing
Reach out to a vet right away if your pet shows any of these symptoms or if you think they might have tick paralysis. Don't wait to see if your pet gets better overnight. Symptoms can keep getting worse even after a tick has been found and taken out.
How to Protect Your Pet During Flea and Tick Season
Consistent prevention is the best way to protect your pet. Check that their treatment is current, inspect their coat regularly and keep their living areas clean.

- Use a flea and tick treatment suitable for your petβs species, age and weight.
- Give each treatment on schedule and set a reminder for the next dose.
- Check your petβs coat after spending time outdoors, especially around the head, neck, ears, toes and tail.
- Wash pet bedding regularly and vacuum carpets, rugs and furniture.
- Speak with your veterinarian if you are unsure which treatment is suitable.
Never use a dog-only treatment on a cat, as some ingredients used in canine products can be highly toxic to cats.
Is Year-Round Protection Necessary?
For many pets in Australia, keeping them protected all year round is the easiest and safest way to go. Fleas can keep growing in warm homes, and ticks might stay active outside their usual peak times in warmer areas.

The best schedule for your pet depends on their needs, where you live, your lifestyle, and the parasites that the product protects against. Some treatments guard against fleas and ticks, while others also protect against heartworm or intestinal worms. Not all products offer the same level of protection.
Your veterinarian can recommend an appropriate parasite control plan based on your petβs individual risk.
Stay Ready Before Parasite Activity Peaks
Flea and tick season often becomes more noticeable during spring, but prevention should begin before the scratching or symptoms start. Consistent treatment, regular coat checks and a cleaner home environment can reduce the risk throughout the year.
