What are the symptoms of a tick bite and how should it be treated?
TL;DR — Quick Answer
Tick bites can cause redness, itching, swelling and irritation. Some people may experience allergic reactions, while paralysis ticks can cause more serious illness. In Australia, attached ticks should generally be killed first using an ether-containing freezing spray before removal to reduce the risk of allergic reactions.
What Are Ticks and Why Are They Common in Sydney?
Ticks are blood-feeding parasites found across Australia, with about 70 known species. Over 95% of human tick bites in eastern Australia come from the paralysis tick (Ixodes holocyclus)—also called grass, seed, or bush tick.
These ticks thrive along the NSW coast, including Sydney’s northern beaches, Central Coast, and bushland suburbs. They climb grass and twigs, then drop onto passing people or animals to feed.
NSW Health data shows tick activity rises from spring to autumn, with wetter conditions boosting populations. Since 2020, tick-related illness notifications have increased by 22% annually in parts of Sydney.

What Does the Paralysis Tick Look Like at Each Life Stage?
Paralysis ticks grow through three main stages before becoming adults:
- Larva: ~1mm long, light brown, often called “seed ticks”
- Nymph: ~2mm long, pale brown, hard to spot on skin
- Adult: ~1cm long, wrinkled grey-blue, leathery texture, flat body and long mouthparts
They need blood to grow and moult. When feeding, they inject saliva that stops clotting and may contain toxins or allergens.
What Symptoms Can You Get From a Tick Bite?
Most bites cause mild redness and swelling that fades once the tick is removed. But other reactions are possible—here’s what to watch for:
Localised Reaction
Redness, swelling, or mild itch around the bite site. This usually clears in 1–2 days.
Tick Paralysis Symptoms
Caused by neurotoxins in saliva—most common in children and pets. Signs include:
- Rash, swollen glands, or facial drooping
- Flu-like aches, headache, fever
- Unsteady walking, weak limbs, joint pain
- Sensitivity to bright light
Paralysis can get worse quickly—seek urgent medical help if you notice these.
Allergic Reaction Symptoms
Severe allergy may cause:
- Throat swelling, trouble breathing
- Dizziness or collapse
About 5000+ Australians now live with tick-induced mammalian meat allergy, with Sydney’s Northern Beaches having one of the world’s highest rates at 744 cases per 100,000 people.
What Is Mammalian Meat Allergy From Tick Bites?
This allergy develops when tick saliva triggers an immune response to a sugar called alpha-gal found in beef, lamb, pork, kangaroo, and gelatin products.
Reactions often happen 3–6 hours after eating meat—unlike most food allergies. A Sydney study found heart attack patients were 12 times more likely to carry alpha-gal antibodies.
Only an allergist can diagnose this. If confirmed, you’ll need to avoid mammalian meat and products with gelatin.
How Do You Safely Remove a Tick?
Stressing or squeezing a tick makes it inject more saliva—raising allergy and illness risk. Follow these NSW Health and ASCIA guidelines:
- Use an ether-based freeze spray (e.g., Wart-Off Freeze, Aerostart). Hold 1cm away and spray 5 times.
- Wait 5 minutes—check if legs stop moving. If alive, spray again 5 times.
- Let the dead tick drop off naturally. Do not pull it out with tweezers.
- Wash the area with soap and water, then apply antiseptic.
What NOT to Do
Never use methylated spirits, petroleum jelly, nail polish, oil, alcohol, or a lit match. These don’t work and may push the tick deeper.
If you cannot remove it safely, have an allergy, or see infection signs visit your nearest doctor or emergency department.

✅ Correct Removal Steps
1. Prepare & Grip
- Use fine-tipped tweezers; clean them first with alcohol/soap.
- Grasp the tick as close to your skin as possible, holding its head/mouthparts — do not squeeze the swollen belly.
2. Pull Steadily
- Pull straight upward with even, constant pressure.
- Do NOT twist, jerk, or yank — this breaks mouthparts and leaves them behind.
3. Clean & Disinfect
- After removal: wash the bite and your hands thoroughly with soap + water or rubbing alcohol.
- Apply antiseptic if available.
4. Dispose or Save
- Do NOT crush with fingers. Choose one:
- Drop into rubbing alcohol
- Seal in a bag/tape
- Flush down the toilet
- Save in a labeled container for testing/identification
❌ What NOT to Do
- No nail polish, petroleum jelly, oil, alcohol, or fire to “suffocate” it — these make the tick regurgitate pathogens.
- No squeezing, burning, or twisting.
- No waiting to remove — do it right away.
If Mouthparts Stay Behind
- If you can easily pick them out with tweezers, do so gently.
- If not: leave them alone — your skin will push them out like a splinter; do not dig deeply.
Aftercare
- Note the date and location of the bite.
- Watch for 30 days for fever, rash (especially bull’s-eye), aches, or fatigue — see a doctor if these appear.
When Should You See a Doctor After a Bite?
Get medical help straight away if you have:
- Constant pain, spreading redness, or streaks from the bite
- Fever, chills, or worsening symptoms days later
- Known tick allergy or history of anaphylaxis—carry your adrenaline autoinjector
Ticks can carry illnesses like Queensland tick typhus, Flinders Island spotted fever, rickettsial infections, and possible Lyme-like conditions.
How Can You Prevent Tick Bites in Sydney and NSW?
Follow these tips to lower your risk when gardening, bushwalking, or living near green spaces:
- Wear long sleeves, long pants, a hat, and tuck trousers into socks
- Use repellent with DEET or picaridin on skin
- Treat clothes with permethrin—kills ticks on contact
- Avoid long grass and bushes after rain or in warm months
- Check your skin, hair, and clothes when you get home
- Dry clothes in a hot dryer for 20 minutes to kill hidden ticks
These steps align with NSW Health and Australian pest management standards for tick control.
Tick Removal Method Comparison
| Method | Effectiveness | Safety | Recommended? |
|---|---|---|---|
| Freeze with ether spray | High – kills in 5–10 mins | Very low saliva injection risk | ✅ Yes – NSW Health/ASCIA approved |
| Tweezers / pulling | Moderate – may leave mouthparts | High – often squeezes saliva out | ⚠️ Only if no spray and no allergy |
| Oil, petroleum jelly, alcohol | Very low – tick stays attached | High – tick may burrow deeper | ❌ No – not recommended |
| Burning with match | Zero – ineffective | Dangerous – burns + stress reaction | ❌ No – unsafe |
