Spiders are part of our everyday lives here in Australia and can be found at home and when we’re out and about.

We’ve put together this guide to the treatment of spider bites and first aid so you know what to do if you or someone else is bitten.

We’ll start by talking you through the types of spiders found in Australia and how to know if they’re dangerous.

Which spiders should I look out for?

Australia has around 2,000 species of spider. While most are not dangerous to humans, some species are venomous.

The Sydney funnel-web spider is considered the most dangerous of all Australian spiders. This is a black spider 1.5 to 5 cm long. The male has distinctive spurs on its second pair of legs. This spider can be found in New South Wales and tends to burrow in quiet, humid places.

There are around 40 species of funnel-web spider in Australia, though only six of these are venomous.

If someone is bitten by any type of funnel-web spider or other big black spider, get help immediately. Call Triple Zero (000) and ask for an ambulance.

Other venomous spiders to look out for include:

  • Redback spiders — around 1 cm long, black with distinctive red stripes on their backs
  • Mouse spiders — 1 to 3 cm, black with red jaws
  • White tail spiders — 1 to 2 cm long, grey or black with a white spot on its tail end

Check out this spider identification chart to learn more about Australian spiders.

If you are helping someone who has been bitten, try to take a photo of the spider if possible. This will help medical staff identify it and offer the most appropriate treatment.

First aid for funnel-web and mouse spider bites

  • Follow DRSABCD. This is a protocol that will guide you through a medical emergency.
  • Get the patient to lie down and keep still.
  • If the bite was on an arm or a leg, apply a compression bandage.
  • If you don’t have a compression bandage, you can apply a regular bandage just over the bite. Then, apply a second one, starting at the fingers or toes and extending as far up the limb as possible. The bandages should be applied tightly so that you can’t slide a finger underneath.
  • Keep the limb immobile with splints.
  • Record the time of the bite and when you put the bandage on.

First aid for redback and other spider bites

  • Wash the bitten area with soap and water.
  • Apply an ice pack to the site for 15 minutes.
  • If pain persists, apply for another 15 minutes.
  • If symptoms worsen, get medical help.
