REDBACK SPIDERS are found Australia-wide. They are common in urban areas, living under eaves, floorboards, shelves, flower pots, and in garden sheds.
Female Redback Spiders are black, sometimes brown, and can be identified by a red or orange stripe on top of their abdomen. They also have an hourglass shaped red or orange marking underneath the abdomen.
The male Redback Spider is usually light brown with white or yellow markings instead of red or orange.
The female generally grows to 1cm, while the male is a modest 5mm.
Redback spiders are nocturnal and usually keep to their own web, however females are known to sometimes steal stored food items from other spider’s webs.
The female is characteristically aggressive and is the only one capable of harming humans. The male’s fangs are incapable of penetrating human skin.
More than 250 victims of Redback Spider bites receive anti-venom each year, while a number of envenomations go unreported, probably because the symptoms were not too serious.
Since Redback Spiders don’t often stray from their webs, it is unlikely a human will be bitten unless they come into direct contact with the web or the female spider.
The bite of the Redback Spider is highly venomous. It is characterised by intense localised pain around the bite site. Other common symptoms of a Redback Spider bite include:
A Redback Spider bite can be life-threatening to a child or pregnant women, but is rarely serious for an adult.
First Aid Management:
The bite site is likely to remain red and itchy for a few days after the bite occurs. If symptoms are still present after 7 days, revisit your doctor.
