Ticks

Ticks are a common and often unwelcome inhabitant of Australia’s diverse ecosystems. They belong to two prominent families, Ixodidae (hard ticks) and Argasidae (soft ticks), with around 70 species found throughout the country. They are most prevalent in the warmer and humid coastal regions, such as Queensland and New South Wales, where they thrive in dense, grassy, or bushy environments. The Paralysis tick, Ixodes holocyclus, is arguably the most notorious species because it can cause severe and even fatal paralysis in pets and humans if not promptly removed.

In addition to causing direct health impacts such as paralysis, ticks are also vectors for several diseases in Australia. These include Lyme-like illness (a topic of ongoing debate in the Australian medical community as classic Lyme disease, caused by Borrelia burgdorferi, is not native to Australia), Queensland tick typhus and Flinders Island spotted fever. A significant challenge is a potential for tick bite allergies, with some people developing a meat allergy known as mammalian meat allergy or alpha-gal syndrome after being bitten by certain tick species. For these reasons, tick awareness and prevention are essential, particularly in high-risk areas, during the warmer months when ticks are most active.

What is the best way to protect my pets from ticks?

Protecting your pets from ticks is essential for their health and preventing ticks from entering your home and potentially biting humans. Here are some ways to keep your pets tick-free:

Use Tick Preventive Products: There are many tick preventive products available, including spot-on treatments, oral medications, tick collars, and even injectable options for dogs. Always use these products as directed and consult your veterinarian about which option is best for your pet.
Regularly Check Your Pets: Check them thoroughly for ticks after your pet has been outside, especially in wooded or grassy areas. Pay particular attention to hidden areas like under the collar, inside the ears, between the toes, and under the tail.
Keep Your Pet’s Environment Clean: Regularly treat your pet’s environment, such as kennels, bedding, and favourite resting spots. Consider using environmental tick treatments.
Maintain Your Yard: Regularly mow your lawn, rake leaves, and trim bushes to reduce the tick habitat in your yard. Avoid allowing your pets to enter areas with tall grass, brush, or leaf litter where ticks are likely present.
Regular Vet Check-ups: Regular veterinary check-ups can help detect ticks and tick-borne diseases early. Your vet can also provide personalised advice for protecting your pet from ticks based on your region and lifestyle.
Consider Vaccination: In some areas, a vaccine is available to protect against certain tick-borne diseases. Talk to your vet to see if this is an appropriate preventive measure for your pet.

Remember, no tick prevention method is 100% effective, so regular check-ups and prompt removal of any ticks you find on your pet are always recommended. If you notice changes in your pet’s behaviour or health, such as fever, loss of appetite, weakness, or swollen joints, consult your veterinarian immediately, as these could be signs of a tick-borne illness.

What is the risk of tick paralysis in Australia?

In Australia, the risk of tick paralysis is primarily associated with the Paralysis tick (Ixodes holocyclus), which is found along the country’s eastern coast. This tick injects a neurotoxin into its host while feeding, which can cause paralysis. The risk is exceptionally high in pets, especially dogs and cats, and can be fatal if not treated promptly.

While rare, humans can also be affected by tick paralysis, particularly children, due to their lower body weight. Symptoms usually start with weakness in the lower limbs and unsteadiness, progressing to complete paralysis. In severe cases, this can affect the respiratory muscles leading to respiratory failure.

The risk of tick paralysis is higher during the warmer months (typically from September to February) when ticks are most active and their numbers are higher. However, they can be present all year round. The best prevention against tick paralysis is avoiding tick bites through personal protective measures, regular checking for ticks, and prompt removal of any attached ticks.

If you or your pet develop any unusual symptoms following a tick bite, such as weakness, instability, or difficulty breathing, immediately seek medical or veterinary attention.

Can ticks transmit diseases in Australia?

Yes, ticks can and do transmit diseases in Australia. Some of the diseases and conditions associated with ticks in Australia include:

Queensland Tick Typhus: This is caused by the bacterium Rickettsia australis, transmitted by several ticks. Symptoms include fever, headache, muscle pain, and often a rash.
Flinders Island Spotted Fever: This is caused by the bacterium Rickettsia honey and is transmitted by the Southern marsupial tick (Ixodes Tasmania). The symptoms are similar to those of Queensland Tick Typhus.
Tick Paralysis: Caused by the neurotoxin produced by certain ticks, most notably the Paralysis tick (Ixodes holocyclus). It primarily affects dogs and cats but can also occasionally affect humans, causing progressive paralysis that can be fatal if not treated.
Mammalian Meat Allergy: Some people may develop a delayed allergic reaction to red meat after being bitten by certain ticks. This is thought to be caused by an immune response to a sugar molecule in the tick’s alpha-gal saliva.
Lyme-like disease: While classic Lyme disease, caused by Borrelia burgdorferi, is not native to Australia, there have been ongoing debates about a local “Lyme-like” disease possibly transmitted by ticks, characterised by similar symptoms.

Remember that the best way to prevent tick-borne diseases is to avoid tick bites in the first place. If you’ve been bitten by a tick and develop symptoms such as fever, rash, muscle or joint pain, or neurological symptoms, seek medical attention promptly and let your healthcare provider know about your recent tick bite.

Where are ticks most commonly found in Australia?

Ticks are found in various regions of Australia, with the highest concentration in the warmer and more humid coastal areas. Ticks thrive in moist, bushy, and grassy environments, making the coastal regions of Queensland and New South Wales particularly suitable for them.

The Paralysis tick (Ixodes holocyclus), the most significant tick species for human and pet health in Australia, is commonly found along the eastern coastline of Australia, from North Queensland to Northern Victoria. This species mainly thrives in areas with a dense population of wildlife hosts, such as bandicoots and possums.

The Brown Dog Tick (Rhipicephalus sanguineus), which can transmit diseases to dogs, is widely distributed across Australia but is most prevalent in warmer regions, especially those in Western Australia, the Northern Territory, and northern parts of South Australia and Queensland.

The Cattle Tick (Rhipicephalus australis) is of significant concern to the livestock industry and is primarily found in Queensland and the Northern Territory.

However, tick distribution can vary and change due to factors such as climate, host availability, and human activities, and ticks can also be found in other regions of Australia. Always take precautions to avoid tick bites in areas that could be infested.

Knowing how to protect yourself from ticks and tick bites is essential, mainly if you live in or visit an area where ticks are common. Here are several tips to help keep you safe:

Avoid Tick Habitats: Ticks thrive in grassy, brushy, or wooded areas or on animals, so avoid these areas when possible, especially during spring and summer when ticks are most active.
Wear Protective Clothing: If you’re going into areas where ticks might be present, wear long sleeves, long pants, and boots or closed shoes, not sandals. Tuck your pants into your socks for extra protection. Light-coloured clothing can also help you spot ticks before they bite.
Use Tick Repellents: Use a repellent that contains at least 20% DEET on exposed skin and clothing. You can also use permethrin on clothing and gear, not the skin.
Check For Ticks: After being outdoors, check your body and your children’s bodies for ticks. Ticks often bite in hard-to-see areas, like the scalp, armpits, and groin, so check these areas carefully. If pets have been outside, check them too, as they can bring ticks into the home.
Remove Ticks Immediately: If you find a tick, remove it as soon as possible. Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible. Pull upward with steady, even pressure, without twisting or jerking, to avoid leaving parts of the tick’s mouth in the skin.
Shower After Outdoor Activities: Showering within two hours of coming indoors can help reduce your risk of tickborne diseases by washing off unattached ticks and providing an excellent opportunity to do a tick check.
Maintain Your Yard: Keep your lawn mowed, remove leaf litter, and trim overgrown bushes or trees that create a calm, shady, humid environment that ticks love.
Seek Medical Attention if Necessary: If you develop a rash, fever, flu-like symptoms, or severe reactions after a tick bite, seek medical attention promptly. Remember to tell the doctor about your recent tick bite, when the bite occurred, and where you most likely acquired the tick.

Australia is home to approximately 70 species of ticks, and they are classified into two prominent families: Ixodidae (hard ticks) and Argasidae (soft ticks). Not all species are significant to human and animal health, but several are known for their potential impacts.

Paralysis Tick (Ixodes holocyclus): The Australian sheep tick or bush tick is the most medically significant in Australia due to its ability to inject neurotoxins, causing paralysis and sometimes death in pets and occasionally humans. It’s predominantly found on the east coast of Australia.
Brown Dog Tick (Rhipicephalus sanguineus): This is a worldwide species and can transmit canine ehrlichiosis. In Australia, it is mainly found in Western Australia, the Northern Territory, and the northern parts of South Australia and Queensland.
Bush Tick (Haemaphysalis longicornis): Found along the eastern seaboard of Australia, this tick is known to bite humans, but it is more of a concern for livestock, causing diseases such as theileriosis in cattle.
Cattle Tick (Rhipicephalus australis): Cattle ticks are a significant concern for the livestock industry as they can transmit diseases like babesiosis and anaplasmosis, causing significant production losses. These ticks are predominantly found in Queensland and the Northern Territory.
Marsupial Tick (Ixodes Tasmania): Found in various parts of Australia, this tick mainly infests wildlife like bandicoots and possums, but will also feed on domestic animals and humans.
Bird Tick (Ixodes eudyptidis): As the name suggests, this tick infests birds but may also bite humans. They are typically found in coastal regions of Australia.

It’s important to note that while these are some of the more well-known species, there are many other tick species in Australia, some of which are not well-studied and whose potential impacts on humans and animals are not fully known. As such, it’s always best to avoid tick bites whenever possible and seek medical advice.

Prompt and proper tick removal can help prevent the transmission of any pathogens the tick may be carrying. Here are step-by-step instructions for safe tick removal:

Prepare Your Tools: Get a pair of fine-tipped tweezers or a tick removal tool. These will allow you to grasp the tick effectively without crushing it.
Grasp the Tick: Use the tweezers to grasp the tick as close to the skin’s surface as possible. Be careful not to squeeze the body of the tick, as this could cause it to release infectious material.
Pull Upwards: With a steady hand, pull the tick straight up and out. Do not twist or jerk the tick, as this may cause the mouthparts to break off and remain in the skin. You want to remove the tick in one piece if possible.
Clean the Bite Area: After successfully removing the tick, clean the bite area with soap and water, rubbing alcohol, or an iodine scrub. This can help prevent infection.
Dispose of the Tick: Do not crush the tick with your fingers. Instead, put it in a sealed bag or container, wrap it tightly in tape, or flush it down the toilet. You can also consider saving the tick for identification if you live in an area where tick-borne diseases are common.
Monitor for Symptoms: Keep an eye on the bite site over the next few weeks for any signs of rash, redness, or swelling. If you notice these or develop symptoms like fever, headache, fatigue, or muscle and joint aches, seek medical attention. Make sure to tell your doctor about the tick bite.
Do Not Use Home Remedies: Methods like using petroleum jelly, nail polish, or a hot match to remove the tick are not effective and can actually increase the chances of transmitting diseases.

Remember, it’s important to seek professional medical help if you’re unsure about the removal or if the tick was engorged, indicating it had been attached for a significant length of time. Also seek medical advice if you cannot remove the entire tick, as mouthparts left in the skin can lead to infection.
