Spider Bite First Aid in Australia: Symptoms, Treatment & Emergency Response

16 Jun 26

Learn Spider Bite First Aid in Australia. Recognise symptoms, treat funnel-web, redback and white-tail bites, and know when to call 000.

Through this guide, you'll find out what to do after being bitten by a spider in Australia, how to deal with bites from funnel-web, redback and white tail spiders and how to look after yourself if bitten.

Why Is Spider Bite First Aid Important?

There are thousands of species of spiders in Australia, but only a few are dangerous to human health. Most spider bites cause only mild pain, redness, or swelling, but in most cases, they do not require medical treatment. However, some can inject a venom which has a nerve affecting action and produces severe symptoms.

Hence, it is essential to be aware of the proper first aid measures. Early intervention will not only help to minimize venom effects; it will also help to optimize the outcome until medical help arrives. Also, learning the difference between a high-risk and low-risk spider bite can help you make decisions when the pressure is on.

Common Spider Bite Symptoms

Symptoms from a spider bite may be different depending on the species of spider, the amount of venom released and the victim's reaction. Some bites are more serious, and result in a higher level of discomfort that requires immediate medical attention, others are mild.

Common signs include:

Itching at the wound site
Redness and swelling
Itching or irritation
Localised skin reactions
Nausea or vomiting
Sweating
Muscle pain
Headache
Difficulty breathing in severe cases

If the symptoms get worse over time, consult a doctor immediately. Additionally, treat the situation as a medical emergency if the person develops difficulty breathing or signs of a severe allergic reaction.

Funnel Web Spider Bite First Aid

How to Identify a Funnel Web Spider

Funnel-web spiders are one of Australia's most dangerous spiders. Typically, they are large, black, and glossy in appearance. Furthermore, they are quite widespread in eastern Australia, under logs, in gardens and around rockeries.

Symptoms of a Funnel Web Bite

Bites from the funnel-web spider are always a medical emergency, as symptoms can appear within a short period. Sometimes, serious side effects can happen within a few hours. Symptoms may include:

Symptoms may include:

Severe pain at the bite site
Tingling around the mouth
Excessive sweating
Difficulty breathing
Muscle twitching
Nausea and vomiting
Increased heart rate
Collapse in severe cases

First Aid for a Funnel Web Bite

In the event of a suspected funnel web bite, do so immediately. Call 000 and ask for emergency medical help. After that, make sure the victim remains calm and still as movement can help spread the venom.

Then cover with a pressure immobilisation bandage which is applied from the bite area up the whole of the limb. Also, use a splint to immobilise the limb if possible. Most importantly, do not wash the bite area as a medical professional may need to view the bite site to help identify it.

Lastly, keep an eye on the individual until the emergency services arrive.

Redback Spider Bite First Aid

How to Identify a Redback Spider

Redback spiders are much smaller than funnel-web spiders. They are usually black and have a distinctive red stripe running down their back. Furthermore, they tend to be in sheds, garages, garden furniture, post boxes and other sheltered areas.

Symptoms of a Redback Bite

Redback bites can be very painful. Symptoms may then slowly progress over the course of several hours, though.

Common symptoms include:

Immediate pain
Increasing pain over several hours
Sweating around the bite area
Nausea
Headache
Muscle weakness
Abdominal pain

First Aid for a Redback Bite

Pressure immobilisation is not recommended for redback spider bites, as it would not work in the same way as for funnel-web bites. Rather, start with soap and water on affected area.

Then, use a cold pack, wrapped in a cloth, to help alleviate pain and discomfort. Next, keep a close watch on symptoms and consult medical help if the pain is becoming too great. Also, call 000 immediately for an ambulance if severe symptoms develop or the person becomes seriously unwell.

Symptoms of a White Tail Spider Bite

Most white tail spider bites are not serious and cause only mild symptoms like:
