Redback spider deaths have raised concerns among many Australians. A recent incident in Sydney has drawn attention to this issue. Redback spiders are present throughout Australia and can be lethal.
Key Takeaways
- A bloke died in 2016 after a redback spider bite led to a bad infection, not from the venom itself.
- No one had died from a redback bite since 1956, when doctors started using antivenom.
- Redback spiders live all over Australia and in other countries too. They like warm, quiet spots near homes.
- Redback bites can cause bad pain, sweating, and feeling sick. About 250 people get antivenom each year.
- To stay safe, wear gloves and shoes when gardening. If bitten, put on ice and get help fast.
Incident Details
A tragic event occurred in Australia in 2016. A man died following a redback spider bite. Initially, it was assumed the spider’s venom was the cause of death. However, this wasn’t the complete picture.
The bite resulted in a severe infection, which ultimately led to his demise, rather than the spider venom itself.
This incident raised concerns about redback spiders. Yet, it’s essential to consider the facts. No fatalities from redback bites have been recorded since 1956 – over 60 years ago. The 2016 case was an unusual occurrence.
It demonstrates the importance of properly cleaning and tending to any bite or wound. Prompt treatment can prevent minor issues from escalating.
Background on Redback Spiders
Redback spiders are well-known in Australia. These small but dangerous creatures have a potent venom. Female redbacks are considered the most hazardous. They reach up to 10 mm in length, while males are much smaller at 3-4 mm.
Their black bodies feature a distinctive bright red stripe on the back, which gives them their name.
These spiders inhabit various locations. They are found in Australia, naturally. They have also spread to Southeast Asia, New Zealand, and even the UAE. Some have been discovered in Japan, Belgium, and the US.
Redbacks are resilient and can survive in diverse environments. They frequently construct webs in quiet, dark areas around homes and gardens. Female redbacks are also adaptable. They can store sperm for up to two years, producing about 250 eggs each time.
We’ll examine how these spiders impact humans and the appropriate actions to take if you encounter one.
Symptoms and Treatment of Redback Spider Bites
Moving from the background of redback spiders, we now focus on the effects of their bites. Redback spider bites can cause serious health issues, but proper treatment can assist.
- Redback spider venom is neurotoxic, leading to a condition called latrodectism.
- Severe pain is often the first indication of a redback spider bite.
- Those affected may experience excessive sweating and severe nausea.
- Vomiting is common after a redback spider bite.
- People who are bitten might experience significant anxiety or distress.
- Medical professionals use an antivenom to treat serious redback spider bites.
- The antivenom was initially developed in 1956 to assist bite victims.
- Approximately 250 people receive the antivenom annually in Australia.
- Medical professionals can administer the antivenom as an intramuscular injection.
- For severe cases, they might administer the antivenom intravenously.
- Some individuals have concerns about potential side effects from the antivenom.
- About 5% of people experience an immediate adverse reaction to the antivenom.
- A small percentage, 1-2%, might experience a severe allergic response.
- One in ten people could experience illness days after receiving the antivenom.
- A study in 2014 suggested the antivenom might not be more effective than a placebo.
- Pain management is a crucial aspect of treating redback spider bites.
- Medical professionals monitor patients closely to ensure their recovery.
Historical Context of Redback Spider Fatalities
After examining redback spider bite symptoms and treatment, we’ll explore their lethal history in Australia. Prior to 1956, redback spiders were responsible for 14 fatalities. While this figure may appear low, it demonstrates the potential danger of these small arachnids.
The year 1956 brought a significant development. It marked the introduction of antivenom for redback spider bites by medical professionals. Since its implementation, there have been no recorded deaths from redback bites.
This outcome demonstrates the effectiveness of the antivenom, representing a significant achievement in Australian medical research. The redback spider, initially documented in 1870 by Tamerlan Thorell, has been recognised by Aboriginal peoples for a considerably longer period.

Signs and Symptoms of Envenomation
Redback spider bites can cause serious health issues. These are the signs and symptoms of envenomation:
- Severe pain at the bite site that can last for days
- Excessive sweating, often starting near the bite
- Nausea and vomiting in many cases
- Feeling restless and agitated
- Symptoms that persist for over 24 hours
- Babies may cry non-stop and refuse to eat
- Kids might get muscle aches and neck spasms
- A general rash can appear on the skin
- The venom has alpha-latrotoxin, which affects nerves
- It causes the body to release excessive neurotransmitters
These symptoms can vary from person to person. The next section will cover redback spider habitats and distribution.
Distribution and Habitat to avoid Redback Spider Deaths
Moving from signs of redback spider bites, let’s examine where these spiders live. Redback spiders thrive in warm, sheltered spots near homes. They spin messy webs in quiet corners, often in urban areas.
These spiders originally inhabited only small dry parts of South and Western Australia. They’ve spread extensively since European settlement. Now, redbacks live all over Australia and even in other countries.
They can be found in New Zealand, Japan, Belgium, and the UAE. Female redbacks live for 2-3 years, while males live just 6-7 months. Baby spiders hatch quickly, in 8-11 days after eggs are laid.
Redbacks have made cities their new home, demonstrating their adaptability.
Predators and Parasitoids
Moving from where redback spiders live, let’s examine what hunts them. Redbacks face threats from other spiders. Black house spiders, cellar spiders, and giant daddy-long-legs spiders all eat redbacks.
These predators help control redback populations.
Redbacks also have unusual mating habits. Males often die during mating. About two-thirds of male redbacks are eaten by females when they mate. This is called sexual cannibalism. Even if males survive, they become unable to mate again.
Baby redbacks can eat each other too. This behaviour supports the survival of the strongest spiders.
Comparison Table: Redback Spider Bites vs. Other Spider Bites
Redback spider bites differ from other spider bites in key ways. Here’s how they compare:
| Feature | Redback Spider Bite | Other Spider Bites |
|---|---|---|
| Venom Amount | 0.08–0.10 mg per bite | Varies by species |
| Pain Level | Intense, lasting pain | Often mild to moderate |
| Symptoms | Sweating, nausea, vomiting | Usually local swelling and redness |
| Antivenom | Available | Not always available |
| First Aid | Ice application, seek medical help | Clean wound, apply cold pack |
| Prevention | Wear gloves and shoes while gardening | Similar precautions for most spiders |
Redback spider bites pose unique risks. Their venom is potent, causing severe pain and symptoms. Unlike many spider bites, redback bites need special care. Wearing gloves and shoes helps prevent bites. If bitten, apply ice and get medical help fast. Redback antivenom exists, unlike for most spider bites. Be careful around spiders and teach kids not to touch them.
