Paralysis ticks, also known as Ixodes holocyclus, are a type of parasitic arachnid found in Australia. They can cause paralysis in humans and animals by injecting neurotoxins into their hosts. Paralysis ticks are found all along the eastern coast of Australia, with some populations in non-coastal areas. They are most prevalent from July to December, but the risk of exposure can be year-round. Western Australia is no exception to paralysis ticks, with the ornate kangaroo tick (Amblyomma triguttatum) being common throughout the state, particularly in the southwest region.

What You'll Learn
Paralysis ticks are found on the east coast of Australia
Paralysis ticks, also known as Ixodes holocyclus, are found on the east coast of Australia. They are arachnids and parasitic in nature. They are one of the three common species of ticks in Australia, with around 70 different types of ticks in the country. They are most prevalent during Australia's tick season, which is usually from July to December, although the risk of exposure can be year-round.
Paralysis ticks can cause paralysis by injecting neurotoxins into their hosts. They are particularly dangerous to dogs, as they carry a potentially lethal toxin for them. In humans, systemic paralysis is possible but now relatively rare. This is because an adult female tick needs to remain attached for several days, and there is now greater medical and public awareness of the problem.
Paralysis ticks are most commonly found in warm and humid conditions, with temperatures around 27°C and high humidity being ideal. They are typically found in grass, on tree branches, logs, leafy debris, and uncontrolled vegetation. They attach themselves to passing hosts by dropping on them and finding an optimal spot to feed. Ticks enjoy feeding on soft skin areas, such as the head and neck region.
To protect yourself from paralysis ticks, it is important to take precautions when venturing into tick-prone areas like bushland or tall grass. This includes wearing long-sleeved shirts, long pants, and closed shoes. It is also recommended to tuck pants into socks for extra protection and to wear light-colored clothing to make it easier to spot a tick. Applying tick repellents or insecticides containing DEET to exposed skin and clothing can also help deter ticks.
In addition to the east coast, paralysis ticks can also be found in some non-coastal areas of Australia. The southern paralysis tick (Ixodes cornuatus) is common in Victoria and Tasmania, while the ornate kangaroo tick (Amblyomma triguttatum) is prevalent in southwest Western Australia.

They can cause paralysis in humans and animals
Paralysis ticks are found in Western Australia, with around 70 different types of ticks present across the country. Ixodes holocyclus, also known as the Australian paralysis tick, is the most common tick that causes paralysis in domestic animals, humans, and wildlife in Australia. It is found on the east coast, with some populations in non-coastal areas.
The paralysis is caused by a neurotoxin transmitted through the tick's saliva, which affects the nervous system. Symptoms include numbness or tingling in the legs, muscle pain, fatigue, and irritability. The numbness then moves up the body, followed by paralysis that starts in the feet and spreads upwards. While tick paralysis is rarely fatal, it is considered an emergency if it affects the diaphragm and makes breathing difficult.
In Australia, there have been at least 20 reported human deaths attributed to the paralysis tick between 1904 and 1945, with 80% of the victims being children under four years old. The first confirmed human death caused by a tick in Australia was reported in 1912 when a child experienced flaccid paralysis progressing to asphyxiation due to an engorged tick.
To prevent tick paralysis, it is essential to avoid tick bites. This can be done by avoiding tick-heavy areas, using tick-deterring bug sprays, and performing daily self-examinations for ticks. If bitten by a tick, it is crucial to remove it as soon as possible using tweezers to grasp the tick close to the skin and pulling slowly and steadily upward. It is important to ensure that the entire tick, including its head and mouthparts, is removed to prevent further infection.

Ticks are arachnids and carry toxins
Ticks are parasitic arachnids that feed on the blood of their hosts, which include mammals, birds, and sometimes reptiles and amphibians. They are related to predatory arthropods such as scorpions, spiders, and mites. Ticks have four life stages: egg, six-legged larva, eight-legged nymph, and adult. The larva feeds on a host and then develops into a nymph. The nymph feeds on a host and moults into an adult. Both male and female adults feed on a host, after which the female lays eggs. Ticks can carry and transmit pathogenic bacteria, helminths, protozoa, and viruses to and from their hosts, including humans and animals.
There are around 70 different types of ticks in Australia, with species found in every state and territory. The most medically significant species is the paralysis tick, Ixodes holocyclus, which is found on the east coast and some non-coastal areas. This species is responsible for over 95% of tick bites in Eastern Australia and most tick-borne illnesses. Ixodes holocyclus feeds on various birds and mammals, but it relies on bandicoots to sustain its life cycle and population.
The saliva of Ixodes holocyclus contains a toxin that causes paralysis, and this toxin is also present in scorpions. While systemic paralysis in humans is now rare, it can still occur, especially in children or situations where ticks attach in hidden places. In the past, paralysis may have been misdiagnosed as polio. Up to 1989, there were 20 reported human fatalities in Australia due to tick paralysis.
To prevent tick bites, it is important to keep lawns well-maintained and free of weeds, as ticks are sensitive to dry conditions and short vegetation. If ticks are present, insecticides can be applied to high weeds. Ticks can be removed with fine-tipped tweezers or tick removal tools, and the bite site should be disinfected. It is important to avoid forcibly removing ticks, as this can cause them to inject allergens or toxins into the bite site, potentially leading to anaphylactic shock.

Ticks can be found in Western Australia, too
The paralysis tick is identified by its dark brown first and last pairs of legs, in contrast to its beige middle pairs. It can cause paralysis in dogs and, very rarely, humans. The tick attaches itself to a host by prying open the skin with hooks in its mouth and gorging on blood. It can attach anywhere but is generally found around the head and neck area.
The scrub tick, Ixodes australiensis, is regularly found on cattle in Western Australia and is known to tolerate hot environments. The bandicoot tick is another species found in Western Australia, as well as the Northern Territory, Queensland, and New South Wales.
The Amblyomma triguttatum, or ornate kangaroo tick, is common throughout Australia, particularly in southwest Western Australia. The brown dog tick, Rhipicephalus linnaei, is also common throughout the country but only bites dogs.
It is important to be aware of the risks associated with ticks and to take precautions when outdoors, especially in bushland or tall grass. Ticks can transmit various diseases, including bacterial and viral infections, allergies, autoimmune disorders, and post-infection fatigue. They can also cause tick paralysis, which has been fatal in some cases.

There are about 70 different types of ticks in Australia
Ticks are parasitic arachnids, and there are around 70 different types of ticks in Australia. They are found in every state and territory, and the most medically significant species is the paralysis tick, Ixodes holocyclus. This tick species is found on the east coast of Australia and in some non-coastal areas, and it is responsible for more than 95% of tick bites in Eastern Australia. It is also known as the Australian paralysis tick or simply paralysis tick.
The paralysis tick has a life cycle consisting of four stages: egg, larva, nymph, and adult. It requires three hosts to complete its life cycle, making it a "three-host tick". The bandicoot is the preferred host, but it also infests other native hosts, including bettongs, koalas, flying foxes, echidnas, birds, domestic animals, and humans. The tick attaches itself to a passing host by piercing the skin with its sharp mouth and can cause paralysis if it remains attached for several days.
While systemic paralysis in humans is possible, it is now a rare occurrence due to increased medical and public awareness. However, paralysis is more likely to occur in children and when ticks attach in places that are not easily detected, such as under bandages. In the past, many cases of ""infantile paralysis," may have been misdiagnosed as polio and were actually cases of tick paralysis.
Other tick species found in Australia include Ixodes cornuatus, commonly known as the southern or Tasmanian paralysis tick, which has also been associated with paralysis in some companion animals. Ixodes tasmani has the most widespread geographic distribution and the broadest range of hosts of any Australian tick. Bothriocroton hydrosauri, previously known as Aponomma hydrosauri, is one of the most commonly studied ticks in Australia and feeds on reptiles, cattle, horses, and humans.
The scrub tick (Ixodes australiensis) is regularly found on cattle in Western Australia and is known to tolerate hot environmental conditions. The bandicoot tick is another tick species found in Western Australia, as well as in the Northern Territory, Queensland, and New South Wales. It can be a vector of the Theileria parasite.
Australian ticks are most prevalent during the warmer months of summer, and they can carry poisonous toxins and bacteria that are harmful to dogs and other animals. They can also cause allergic reactions in humans, ranging from mild symptoms such as swelling and redness to anaphylactic shock.
