Spring has well and truly arrived, and for pet owners along Australia’s eastern seaboard that means one thing: paralysis tick season. These tiny parasites cause more pet deaths in Australia than snake bites, spider bites and wasp stings combined, so it pays to be prepared before you find one on your mate.
The good news? Paralysis tick paralysis is highly preventable and, when caught early, highly treatable. Here’s everything you need to know to keep your dog or cat safe this season.
What Exactly Is a Paralysis Tick?
The paralysis tick (Ixodes holocyclus) is Australia’s most dangerous tick. It’s found mainly along the eastern seaboard — from North Queensland down through New South Wales and into Victoria — and it’s most active in warm, humid weather.
Here’s the creepy part: the tick doesn’t need to stay attached for long to cause serious harm. A single female tick attached for three to four days can inject enough toxin to paralyse a dog, and just one tick can kill a cat. The toxin affects the nervous system, slowly shutting down your pet’s ability to move, swallow and eventually breathe.
Ticks pick up the toxin from native wildlife like bandicoots and possums, which is why bushland, long grass and leafy backyards are prime tick territory. Even city pets aren’t safe — ticks can ride in on dogs walked in reserves or on possums visiting your roof at night.
When Is Tick Season in Australia?
Depending on where you live, paralysis tick season runs from around August through to March — roughly spring to autumn. The warmer and more humid the weather, the more active the ticks are.
In tropical and subtropical areas like Queensland and northern NSW, ticks can be a problem all year round. And with climate change pushing temperatures up, the season is starting earlier and lasting longer in southern states too. If you live in a tick area, prevention should be a year-round habit, not a spring afterthought.
The Warning Signs Every Owner Should Know
Knowing the early signs of tick paralysis can be the difference between a quick recovery and a tragedy. In dogs, watch for:
- A wobbly or unsteady gait, especially in the back legs
- A change in bark — weak, hoarse or “lost voice”
- Coughing, gagging or retching
- Vomiting or a sudden loss of appetite
- Laboured or rapid breathing (a late, emergency sign)
In cats, the signs are often subtler. Your cat might just seem quiet, wobbly, or have a meow that sounds different. Some cats deteriorate very quickly once symptoms appear.
Here’s the golden rule: if your pet shows any of these signs during tick season, get to the vet immediately — even if you haven’t found a tick. The antiserum works best when given early.
How to Do a Proper Tick Check
During tick season, do a daily tick search — every day, not just after bushwalks. Run your fingers through your pet’s fur against the grain and feel for small lumps or bumps the size of a pea or grape. Ticks love these spots:
- Around the head, ears and neck
- Under the collar
- In the armpits and groin
- Between the toes and paw pads
A fine-tooth comb helps for short coats, but your fingers are your best tool — ticks can be tiny and hard to spot by eye alone. Make it part of your evening routine, and remember that a tick can hide in a long coat for days without being noticed.
Preventing Ticks the Right Way
The most reliable protection is a vet-recommended tick preventative — spot-on treatments, tick collars or chews. Your vet will help you pick the right product for your pet’s size, age and lifestyle, so never buy “one size fits all” treatments online.
One critical warning: dog tick products can be deadly to cats. Products containing permethrin are safe for dogs but highly toxic to felines, so always check the label and keep treated dogs away from cats while the product is wet.
Around the yard, keep grass short, clear leaf litter and brush piles, and try to discourage bandicoots and possums from hanging around your backyard. Skip the DIY “natural” remedies — eucalyptus and tea tree oils don’t repel ticks reliably and can be toxic to pets.
Found a Tick? Here’s What to Do
Stay calm. Remove the tick with a tick twister or fine-tipped tweezers, grasping as close to the skin as possible and pulling steadily — don’t squeeze the tick’s body, as that can push more toxin into your pet. Pop the tick in a jar or baggie and head to the phone.
Call your vet immediately, even if your pet seems completely fine. Symptoms can appear up to a few days after the tick is removed, and vets often recommend bringing pets in for observation. Don’t douse the tick in alcohol, methylated spirits or a match — these can make it inject more toxin before it lets go.
What About Other Aussie Ticks?
Not all ticks cause paralysis. The brown dog tick and bush tick are less dangerous, but they can still cause skin irritation, anaemia and transmit other diseases. A good tick prevention program covers these as well, so you’re protected across the board.
Paralysis ticks are one of the biggest threats to Aussie pets, but a daily check, the right preventative and a fast call to your vet make all the difference. When in doubt, phone your vet — it’s always better to ask than to wait.
