FUNNEL-WEB SPIDER BITE EMERGENCY

Funnel-Web Spider Bite First Aid: Pressure Immobilisation and 000

Call 000, stop movement and apply pressure immobilisation immediately—do not wait for symptoms.

First aid steps

1. Call 000 and say a funnel-web or big-black-spider bite is suspected.
2. Keep the person lying flat, calm and completely still.
3. Apply a pressure bandage over the bite, then wrap the entire limb and immobilise it with a splint.
4. Mark the bite location if known. Keep checking response and normal breathing.
5. Start CPR if the person is unresponsive and not breathing normally. Leave the bandage on for paramedics.

Use the complete pressure immobilisation technique for the illustrated bandaging sequence.

Treat uncertainty as part of the emergency

Funnel-web spiders occur mainly in eastern Australia, with several medically important species—not only the Sydney funnel-web. Mouse spider bites can produce a similar clinical picture and are managed with the same first-aid caution. A large dark spider may also be a harmless trapdoor or house spider, but a bystander cannot safely resolve that uncertainty while serious envenomation is developing.

If a bite from a funnel-web or other big black spider is possible, call 000 immediately. Do not wait for the spider to be identified, for symptoms to appear or for a photo to be posted online. Keep the person flat and still and apply pressure immobilisation to a bitten limb. The cost of treating a harmless bite cautiously is small compared with delaying first aid for a dangerous one.

Clues from the setting—without overconfidence

Funnel-webs favour cool, moist shelter and may be encountered around burrows, gardens, logs, rocks, shoes, garages, sheds and swimming pools. Wandering males are more likely to be seen after humid or wet weather. These clues can raise suspicion, but location does not prove species and a dry indoor setting does not rule one out.

Symptoms

Severe pain may occur at the bite site. Early systemic effects can include tingling around the mouth, sweating, nausea, vomiting, drooling, breathing difficulty, muscle twitching, agitation, confusion, weakness and collapse. Deterioration can be rapid, so first aid starts on suspicion—not after a symptom checklist is complete.

The first ten minutes: assign roles and reduce movement

1. Move people away from the spider. Do not chase, handle or trap it.
2. Have the casualty lie flat and remain completely still.
3. Call 000 on speaker and clearly say “suspected funnel-web spider bite”.
4. Bring broad roller bandages and a splint to the casualty rather than moving them.
5. Apply pressure immobilisation, note the time and keep monitoring response and breathing.

If several people are present, one should manage the emergency call, one should bandage, and another can guide paramedics to the location. Keep pets and onlookers away. Unlock gates, turn on outside lights and send location details without asking the casualty to stand or walk.

Applying pressure immobilisation with purpose

Venom from a limb bite can move through the lymphatic system, which is strongly influenced by muscle movement. The bandage provides firm tissue pressure while the splint and complete stillness reduce movement. Cover the bite area, then bandage the whole limb from the fingers or toes upward. Apply firm, even pressure comparable to bandaging a sprained ankle—not a tourniquet.

Leave fingers or toes visible when practical so colour and warmth can be observed. Splint the limb and secure it without repeatedly lifting or bending it. Mark the bite location on the bandage if known and write down the application time. The complete illustrated sequence belongs in the shared pressure immobilisation guide; the emergency principle here is to bandage promptly and move the person as little as possible.

Common errors that weaken first aid

• Letting the person walk to a vehicle or bathroom before bandaging.
• Wrapping only a short area around the bite instead of the whole limb.
• Using a narrow, extremely tight band that acts like a tourniquet.
• Skipping the splint and allowing the limb to keep moving.
• Removing the bandage to check the bite or because symptoms seem absent.
• Delaying 000 while trying to capture or identify the spider.

Recognising the emergency pattern

Funnel-web spiders are large, dark and glossy, but visual identification under stress is unreliable and other spiders can look similar. ANZCOR advises treating a suspected bite from a funnel-web or big black spider as a medical emergency. Never put hands near the spider or attempt capture.

Symptoms can become severe quickly

A funnel-web bite may cause immediate pain and visible fang marks, but the danger is the developing whole-body pattern. Warning signs include sweating, tingling around the mouth, nausea, vomiting, abdominal pain, drooling, watery eyes, goosebumps, muscle twitching or spasms, agitation, confusion, breathing difficulty and collapse. Severe effects can progress rapidly, which is why first aid begins before symptoms.

Do not use the person’s current ability to talk as proof that the bite is mild. Keep observing without asking them to move. Note changes in speech, alertness, breathing, sweating, saliva, vomiting and muscle control. If the person becomes unresponsive and is not breathing normally, begin CPR. Leave the pressure bandage in place while following the 000 call-taker’s directions.

Children may show distress differently

A young child may be unable to describe tingling, spreading symptoms or the bite itself. Persistent crying, drooling, vomiting, unusual agitation, drowsiness or collapse after contact with a suspicious spider should be taken seriously. Do not allow a child to walk around while adults decide what the spider was. Use the same emergency pathway and tell 000 the child’s age and observed changes.

Do not wash, cut or manipulate the bite

Do not cut the wound, suck venom, apply chemicals or use a tight tourniquet. Avoid washing the bite because material on the skin may assist later assessment. Do not massage the limb or repeatedly test movement. If the person vomits, protect the airway with the least movement possible and follow emergency call instructions.

What not to do

• Do not let the person walk or sit up unnecessarily.
• Do not wash, cut or suck the bite.
• Do not use a tourniquet or place ice on the bite.
• Do not remove the pressure bandage when symptoms change.
• Do not delay 000 while searching online for spider identification.

Hospital treatment and antivenom

Paramedics and hospital teams provide airway and breathing support, monitoring, symptom treatment and antivenom when clinically indicated. Early pressure immobilisation and rapid emergency care buy time; they do not replace medical treatment.

Give paramedics a concise handover

State the time and location of the bite, where on the body it occurred, what the spider looked like only if actually seen, and whether the person moved afterward. Give the time pressure immobilisation was applied and describe every symptom or change. Mention medicines, allergies and relevant health conditions. Show a safe photograph if available, but never transport a live spider with the casualty.

What happens at hospital

Hospital teams continue resuscitation monitoring and assess for signs of envenomation. Funnel-web antivenom is available for clinically significant bites and is administered in a setting prepared to manage severe illness and treatment reactions. The bandage is removed under clinical control rather than casually in the field, because releasing pressure and moving the limb can change venom movement.

The absence of immediate symptoms does not authorise a person to remove the bandage and go home. Observation and discharge decisions belong to the treating clinical team. The person may need repeated assessment even if early first aid appears to have contained symptoms.

Preventing bites without creating new risk

Wear gloves when gardening or moving rocks, logs and stored materials. Keep footwear indoors or shake it out before putting it on, especially after damp weather. Use care around pool filters and objects retrieved from pools; a spider that appears drowned may still be alive. Reduce damp clutter close to the house and use a torch when working in dark outdoor spaces.

If a funnel-web is found, keep people and pets away. Do not handle it for identification or attempt a capture unless there is no risk and you already know a safe method. For most households, professional removal is the sensible choice. Prevention is about avoiding accidental contact, not proving bravery around a medically important spider.

Funnel-webs around pools and after wet weather

Funnel-webs can wander after humid or wet conditions and may fall into swimming pools. A spider on the bottom of a pool should not be assumed dead; funnel-webs can survive submerged for a considerable time by trapping air. Keep swimmers away, use long-handled equipment only if it can be done safely, and seek professional assistance when uncertain. Never pick one up by hand.

After storms, check shoes, towels, pool equipment and objects left on the ground. Use gloves for debris and a torch in dark, damp spaces. These precautions are especially useful where children or pets use the same areas and may reach into hiding places without looking.

When ambulance access will take time

Tell 000 immediately about remote access, locked gates, steep tracks, building levels or poor phone reception. Send an uninjured person to guide responders while someone stays with the casualty. Do not carry or walk the person toward the ambulance unless directed because muscle movement can accelerate lymphatic venom movement.

Keep the scene safe without collecting the spider

Identification is secondary. If a photograph can be taken from a safe distance, preserve it, but do not put a jar, shoe or hand near an agitated spider. A second bite creates another casualty and distracts from bandaging and observation. Paramedics can treat the suspected exposure without receiving the spider.

Following the event, replace bandages, review how promptly 000 was called and practise the full pressure-immobilisation sequence. Rare emergencies are exactly the skills most likely to fade without rehearsal.
