Australia is home to a variety of fascinating yet sometimes dangerous wildlife, and the Redback Spider is no exception. This iconic arachnid is known for its striking appearance and venomous bite, making it one of the country’s most well-recognised spiders. From its
venomous bite to its bold appearance, uncover the essentials about the Redback
Spider and learn how to protect yourself and your loved ones.
Appearance
The Redback Spider (Latrodectus hasseltii) is easily identifiable by its glossy black body and the distinctive red or orange stripe running along its back. Females are larger, measuring about 1 cm in body length, while male Redback Spiders are smaller and less conspicuous, often appearing brown with faint markings. A female redback spider can lay up to 250 eggs at one time. These eggs are enclosed in a silk egg sack.
Redback Spider Habitat
Redback Spiders are highly adaptable and can be found throughout Australia, often in urban and suburban environments. They prefer warm, sheltered areas such as:
Garden sheds
Under outdoor furniture
Inside letterboxes
Under eaves of buildings
In and under children’s play equipment
In corners of buildings, fences, or verandas
Around plumbing or toilets
These spiders often incorporate leaf matter, twigs and other debris into their tangled webs which helps with web camouflage and stability and potentially trapping prey more effectively.
Behaviour
Redbacks are generally not aggressive and prefer to stay hidden in their webs. However, they can become a threat if disturbed. They primarily feed on insects, and larger females have been known to trap and consume small lizards and other prey caught in their sticky webs.
Signs of a Redback Spider Bite
While bites are rarely fatal, they can occur when the spider feels threatened. However, a Redback Spider bite can be dangerous, particularly for children. The venom of a
Redback Spider contains neurotoxins and can cause a condition known as “Redback envenomation”. Symptoms include:
Pain and swelling: The bite site will often become red, swollen and very painful.
Systemic symptoms: In more severe cases, symptoms can include nausea, vomiting, sweating and abdominal pain (due to spread of venom through the body).
Toxic reactions: In rare cases, especially in young children, elderly individuals or those with compromised health, the bite could cause more severe symptoms like muscle weakness, dizziness or respiratory distress.
While fatalities are extremely rare, it’s important to seek medical attention immediately, especially if signs of severe symptoms are exhibited. The anti-venom for Redback Spider bites can significantly reduce the acuteness of symptoms if administered promptly.
Redback Spider Safety and Prevention:
To minimise the risk of encountering Redback Spiders, consider these safety tips:
Inspect outdoor areas regularly: Check for webs in common hiding spots like sheds, outdoor furniture, and play equipment.
Wear gloves: Always wear gloves when gardening, moving rocks or handling outdoor objects.
Seal entry points: Close gaps, cracks and crevices in and around your home to prevent spiders from entering.
Keep areas clean: Remove clutter, woodpiles and debris where spiders might build their webs.
Pest Control for Redback Spiders
If you spot a Redback Spider, avoid disturbing it. Calling Pest Control depends on:
Location and proximity of people: If the spider is in an area that people often frequent, particularly children or pets, immediately contact PESTMAC Pest Control Solutions to safely treat the areas in and around your home.
Best practice: Ensuring that your property remains protected with the help of longer-lasting repellents, scheduled (annually) maintenance for a General Pest Treatment is 'best practice' to target spider infestations and discourage their return by addressing both active pests and potential breeding sites effectively.
Conclusion
The Redback Spider is integral to Australia’s natural ecosystem, its venom makes vigilance crucial. To co-exist safely with these iconic spiders, it’s important to know their habits, locate their habitats, and practice prevention.
The changing seasons significantly impactthe Redback Spider's behaviour and activity levels. During the warmer months, particularly in spring and summer, Redbacks become more active as they hunt for food and reproduce. This increased activity can lead to more encounters with humans, especially as they build webs in sheltered areas around homes.
