Spiders

In Australia, the only spiders to cause harm to humans are the redback spider and the funnel-web spider.

Funnel-web spider

This spider is large, black and its bite can be life-threatening. There are a number of  black spiders that look similar so if in doubt, treat a bite as if it were from a funnel-web spider.

A bite from a funnel-web spider will usually cause severe pain, nausea, sweating and vomiting, difficulty breathing and muscle twitching.

First aid

  • Call 000.
  • Remove person from danger.
  • Keep the person still.
  • Apply a pressure bandage around the bite and entire limb.
  • Call the Poisons Information Centre on 13 11 26 for more information.

Redback spider

Bites from this spider are venomous but not life-threatening.

The red back spider is found throughout Australia. The female redback spider has a red or orange stripe on its back. The male is very small usually with no stripe.

A redback spider bite may result in pain and redness at the bite site. Other symptoms can include sweating, nausea, vomiting and headaches.

First aid

  • Wash the area and keep it clean.
  • Do not apply a pressure bandage.
  • Call the Poisons Information Centre on 13 11 26.
  • Visit the nearest hospital if symptoms are severe.

Routine use of anti-venom is no longer recommended as research shows anti-venom has a low response rate.
