Bites and stings

Victorian Poisons Information Centre – 13 11 26

There are many Australian species that bite or stings, such as insects, bees, wasps, ants, mosquitos, ticks, scorpions, caterpillars, centipedes, spiders, snakes and sea creatures. Some bites and stings may be harmless and not require treatment, others may be venomous or cause a severe allergic reaction (anaphylaxis) and require medical treatment promptly.

Allergies to venoms from stinging insects (bees, wasps and ants) are one of the most common causes of severe allergic reactions (anaphylaxis) in Australia. Symptoms of anaphylaxis include:

  • A rash.
  • Swelling of the tongue or throat.
  • Trouble breathing.
  • Abdominal pain.
  • Diarrhoea.
  • Vomiting.
  • A drop in blood pressure (shock).

Anaphylaxis from stinging insect allergy results in an average of three deaths per year in Australia. Those with a known allergy should be seen by a medical specialist (clinical immunology/allergy specialist) to develop a strategy for managing subsequent bites or stings and have two adrenaline auto-injectors (e.g. EpiPen®, AnaPen®) readily available to treat anaphylaxis.

People at greater risk of severe reactions to spider venom include babies, young children, the elderly and people with an existing heart condition.

In the event of a venomous bite or sting –

  • Call triple zero (000) for an ambulance in an emergency.
  • Keep casualty as still as possible.
  • Use the Pressure Immobilisation Technique (PIT) for venomous bites/stings and other bites if allergic. Apply pressure to the wound with a firm (10-15cm wide) elasticised bandage – use a second wide bandage starting at the toes or fingers and bandage up the limb as far as possible.
  • Do not apply a tourniquet.
  • Do not remove the bandage at any stage and mark the bandage at the site of the bite or sting. This will enable medical staff to locate the site for inspection without removing the bandage.

If the person collapses or stops breathing, you will need to apply CPR (cardiopulmonary resuscitation) until medical help arrives.

If needing more information call the Victorian Poisons Information Centre on 13 11 26 – seven days a week, 24 hours a day.

Important Note: Applying firm pressure immobilisation with a bandage to a Red Back spider bite can cause more damage to the tissue around the bite site. It is recommended to apply a cold pack to help with the pain. Ensure that ice doesn’t come into direct contact with the skin for more than 20mins and seek medical help.

Fast facts:

  • Many Australian species can bite or sting, some may be harmless, and others may be venomous or cause allergic or anaphylactic reactions.
  • If you’re known to have a severe allergy to the bite or sting of a species – have a management plan and carry an adrenaline auto-injector (EpiPen® or AnaPen®).
  • Don’t use tourniquets on bites, cut the puncture site or try to suck out the venom.
  • Seek medical assistance immediately
  • Call triple zero (000) for an ambulance in an emergency.
