Emergency Spider Bite Information
If bitten by a funnel-web or mouse spider, apply pressure immobilisation bandage and call 000 immediately. Canberra Hospital has antivenom stocks. For redback bites, apply ice and present to Emergency.
Australia is home to some of the world’s most venomous spiders, and Canberra is no exception. While most of the estimated 10,000 spider species in Australia are harmless, several dangerous species thrive in the ACT region. Knowing how to identify them, understanding their behaviour, and knowing the correct first aid response could save a life.
Canberra’s Most Dangerous Spiders: Full Profiles
Where Dangerous Spiders Hide in Canberra Homes
Understanding spider behaviour helps you avoid unexpected encounters. Each dangerous species has preferred habitats:
Funnel-webs prefer moist, sheltered areas. After heavy rain — which Canberra experiences regularly in spring and summer — male funnel-webs wander in search of mates and frequently enter homes through open doors, gaps under garage doors, or ground-level windows. Rockeries, retaining walls, and densely planted garden beds are prime funnel-web territory.
Redbacks favour dry, undisturbed sheltered spots. They’re commonly found under outdoor furniture, inside seldom-used garden sheds, beneath the lips of pot plants, inside letterboxes, around pool pump equipment, and under playground equipment. Always check before reaching into dark, sheltered spaces.
White-tails are active hunters that don’t build webs. They roam at night hunting other spiders, which means they often end up inside homes, in clothing left on floors, in bed linen, and inside shoes. They’re found year-round across Canberra.
Seasonal Patterns of Dangerous Spiders in Canberra
Spider activity in Canberra follows clear seasonal patterns influenced by temperature, rainfall, and breeding cycles:
| Season | Active Species | Activity Level |
|---|---|---|
| Spring (Sep–Nov) | Redbacks emerging, funnel-webs becoming active | Increasing |
| Summer (Dec–Feb) | Peak redback activity, funnel-webs after rain, white-tails active | Peak |
| Autumn (Mar–May) | Male spiders wandering for mates — most indoor sightings | High |
| Winter (Jun–Aug) | Reduced activity, white-tails still present indoors | Low |

Frequently Asked Questions
The funnel-web spider is the most dangerous spider found in the Canberra region. While less common than in Sydney, funnel-webs are present in the ACT, particularly in moist garden areas and after heavy rain. Their bite is a medical emergency requiring immediate hospital treatment and antivenom.
Yes. Redback spiders are common across Canberra. They favour sheltered, dry locations like garden sheds, under outdoor furniture, inside letterboxes, and around pool equipment. While bites are painful, antivenom is readily available at Canberra Hospital and Calvary Hospital.
For funnel-web bites: apply a pressure immobilisation bandage and call 000 immediately. For redback bites: apply ice and seek medical attention — do NOT bandage. For other bites: clean the wound, apply ice, and see a GP if symptoms worsen. Try to capture or photograph the spider for identification.
Retail spider sprays can kill individual spiders on contact but won’t eliminate an established population. Dangerous species like redbacks breed in hidden areas that homeowners can’t easily access. Professional pest control uses targeted treatments in harbourage areas for lasting protection.
