What You'll Learn
Symptoms of spider bites vary depending on the spider
Spiders bite only when they feel threatened or frightened, and most spiders are not inclined to bite. In Australia, only two spiders can kill with a direct bite: the Redback and the Sydney Funnel-web. Since the introduction of antivenom, deaths from spider bites have become extremely rare. However, some spider bites can be harmful and require emergency medical treatment.
The Redback spider is one of the most common spiders in Australia, often found in backyards and human structures. While the Redback is not aggressive, it will bite if it feels threatened, and its bite may require antivenom. The Sydney Funnel-web is another highly venomous spider found in eastern Australia and some neighbouring states. It is known for chasing and biting people, even through shoe leather. Bites from the Funnel-web and other large black spiders are considered a medical emergency and can be life-threatening.
White-tail spiders are also common in Australia and are found in most homes. Their bites are not considered dangerous to humans and typically cause only temporary skin irritation. However, some experts disagree on whether their bites can cause skin ulcers and slow-healing wounds.
Overall, while spider bites can be frightening, they are relatively rare, and most spiders are not harmful to humans. It is always important to seek medical advice if you are unsure or if symptoms persist or worsen.

Most spider bites occur when spiders feel threatened
Spiders are typically non-aggressive towards humans and only bite when they feel threatened and need to defend themselves. Spiders use venom to paralyse their prey, and they may bite when they feel frightened or threatened, even if no harm is intended. Most spider bites are harmless and can be treated at home. The pain of most spider bites can be managed with a cold pack, and over-the-counter antihistamines or NSAIDs can be taken to reduce itching and pain.
In Australia, it can be difficult to know if a spider bite is dangerous or not. Most spider bites cause only local irritation where the bite occurred. However, some spider bites can cause severe symptoms and may require medical attention. The funnel-web spider and the redback spider, for example, are known to cause harm to humans. The female redback spider is particularly dangerous and may require antivenom. Bites from these spiders can be very dangerous and even cause death.
Some people may be more at risk of spider bites than others due to their jobs or actions putting them in closer contact with spiders' natural habitats. These include outdoor workers such as landscapers, groundskeepers, and farmworkers, as well as children playing in piles of leaves or rocks. It is important to familiarise yourself with the kinds of spiders that tend to live around your home and garden to assess your risk of spider bites.
Identifying a spider bite can be challenging, as many bug bites and skin sores can look similar. Worldwide, only a few spider species have fangs long enough to penetrate human skin and venom strong enough to be harmful. Widow spiders and recluse spiders are among the most venomous, with about 30 species of widow spiders and over 140 species of recluse spiders worldwide. Symptoms of a widow spider bite may include redness, pain, swelling, abdominal cramping, nausea, vomiting, tremors, and sweating. Recluse spider bites can cause increasing pain over time and may result in skin ulcers.
If you are unsure whether a bite is from a dangerous spider, it is important to seek medical attention, especially if you experience severe pain, abdominal cramping, breathing difficulties, or other concerning symptoms.

Funnel-web spiders are aggressive and dangerous
Funnel-web spiders are considered one of Australia's most fearsome spiders, and their bite can be extremely dangerous. The spiders are native to eastern Australia, usually found within a 100 km radius of Sydney, and are mostly terrestrial, favouring habitats with moist sand and clay. They are large, black, and aggressive, with prominent fangs and a body length ranging from 1 to 5 cm. The male of the species is particularly dangerous and is known to wander into houses during the summer, especially in wet weather.
Funnel-web spiders are venomous, and their bite can cause serious illness or death in humans if left untreated. The venom contains a type of neurotoxin called delta-hexatoxin, which attacks the nervous system, causing nerves to fire repeatedly. In severe cases, the venom can lead to muscle spasms, a drop in blood pressure, coma, organ failure, and death within a few hours. While funnel-web spiders are not specifically out to harm humans, their venom is unfortunately very harmful to us.
Before the development of antivenom in 1980, there were 13 known fatalities from funnel-web spider bites. Since the introduction of antivenom, there have been no recorded deaths in Australia from confirmed funnel-web spider bites. However, it is crucial to seek immediate medical attention if bitten by a funnel-web spider, as the illness caused by their bites can progress rapidly, and death can occur within minutes to hours.
To identify a funnel-web spider bite, one may experience extreme pain at the bite site, along with redness, swelling, and itching. These symptoms can also be indicative of other spider bites, as most spider bites cause local irritation. However, the severity of a funnel-web spider bite may be indicated by the amount of venom injected, and symptoms can develop quickly if effective first aid is not employed. If you suspect a funnel-web spider bite, it is essential to call emergency services and seek medical attention immediately.

Redback spider bites are dangerous and may require antivenom
Spiders generally bite humans when they feel threatened or frightened. While most spiders in Australia are harmless, the country is home to some of the world's most venomous spiders. These include the funnel-web spider and the redback spider, whose bites can cause harm to humans.
The redback spider is one of the most famous Australian spiders, known for its distinctive black and shiny body with a red or orange hourglass marking underneath its abdomen. Redback spiders are common in places where humans live, building their webs in dry, sheltered areas like sheds and beneath stairs. They are not aggressive and only bite as a last resort, usually when their web is disturbed or someone accidentally puts their hand in their hiding place.
If you are bitten by a redback spider, it is important to remain calm and seek medical attention. Most redback spider bites can be treated at home with first aid, but it is always a good idea to speak to a doctor or nurse for advice. In the meantime, you can apply a cold pack to the bite to help with the pain and minimize swelling. It is helpful to take a picture of the spider or describe its features, including size, colour, and where it was when it bit you, as this will assist medical staff in identifying the spider and providing appropriate treatment.

Most spider bites can be treated with first aid
Spider bites in Australia can be scary, but most can be treated with first aid. While Australia is home to some of the world's most venomous spiders, death from spider bites is rare. Still, it's important to know how to respond in case you're ever bitten.
First, remain calm and assess the situation. Most spider bites are not harmful and only cause local irritation, such as redness, swelling, and mild pain. You can manage the pain with a cold pack and over-the-counter medications like ibuprofen. If the bite itches, take an antihistamine like Benadryl.
If possible, try to identify the spider. This will help you determine the next steps. For example, funnel-web spiders and big black spiders, such as mouse spiders, are highly dangerous and require immediate medical attention. If you are bitten by one of these spiders, call triple zero (000) and ask for an ambulance.
On the other hand, white-tail spiders and redback spiders are not usually dangerous to humans. While redback spider bites may require antivenom, they can often be treated at home. White-tail spider bites can be painful and cause temporary skin irritation, but they are unlikely to cause skin ulcers or slow-healing wounds.
To catch the spider, place a container over it and slide a piece of stiff cardboard beneath the container to seal it. Turn the container upside down, remove the cardboard, and attach the lid. If you can't catch the spider, take a photo or note its size, colour, and any other distinctive features. This information will be helpful to medical staff.
Remember, it can be challenging to determine if a spider bite is dangerous in Australia. If you are unsure, always seek medical advice. You can call healthdirect Australia to speak with a nurse or doctor, or use the Symptom Checker on their website to guide you to the appropriate healthcare steps.
