The redback spider is a highly venomous spider. It is thought to come from Australia, but it now also lives in Southeast Asia, Japan and New Zealand. It often lives close to people, in warm, sheltered places in and around homes, so it matters a great deal for safety.1

It lives in warm, sheltered places, commonly near or inside human homes and other buildings. Food scraps and lights attract the insects it hunts, which brings the redback closer to people.1

It mainly catches insects, but also spiders, small lizards and occasionally even snakes or a mouse that become caught in its web. It squirts sticky silk over the prey, bites it repeatedly, wraps it in silk, then sucks out its liquefied insides back at its retreat.1

The venom is neurotoxic to vertebrates, meaning it attacks the nerves, and it causes a condition called latrodectism. Pain starts around the bite and typically becomes severe, spreading up the bitten limb and lasting for over 24 hours. Localised sweating in patches of skin is highly indicative of latrodectism, and nausea, vomiting, headache and agitation may indicate severe envenomation.1

The redback is one of the few spider species that can seriously harm humans. Because it often lives in buildings, it is responsible for a large number of serious spider bites in Australia.1

Dintlha

A male redback can successfully mate with a female katipō, a related New Zealand spider, producing hybrid offspring.1

Males often mate with a female who may then eat them, a behaviour called sexual cannibalism that many arachnids show while mating.1

In laboratory tests, redbacks survived an average of 100 days, and sometimes over 300 days, without food.1

After mating, a female can store sperm for up to two years and use it to fertilise several clutches of eggs.1

Spiderlings and larger females steal food from other spiders' webs, and spiderlings sometimes eat their less active siblings.1
