The Redback spider (Latrodectus hasselti) is an iconic, venomous arachnid native to Australia and a close relative of the North American black widow. It is most easily recognised by the striking red or orange stripe on the back of the female’s spherical, black abdomen.
They thrive in human environments, often building messy, tangled webs in dry, sheltered spots like sheds, garages, under outdoor furniture, or in letterboxes. They are primarily insectivorous, but their strong silk allows them to trap larger prey such as lizards, small snakes, and mice. Behaviour: They are generally shy and non-aggressive, only biting when their web is disturbed or they are accidentally touched.
While the female redback is one of Australia's most medically significant spiders, their bites are rarely life-threatening. Intense localised pain is the most common symptom. Severe envenomation (latrodectism) can cause progressive pain, nausea, vomiting, headaches, and patchy sweating.
