Dangerous or Just a Nuisance? The Key Spiders to Know
The Gold Coast’s warm climate is perfect for a wide variety of spiders. While most are harmless and beneficial for controlling other insects, a few require caution.
The Dangerous Ones
Redback Spider (Latrodectus hasselti)
This is the spider that warrants the most respect. The female is the dangerous one, and her bite can be medically significant.
- Identification: A pea-sized, black, velvety body with a prominent red or orange stripe on the upper side of her abdomen. Her web is a messy, tangled-looking structure, usually built in dry, sheltered locations like under outdoor furniture, in mailboxes, or among stored rubbish.
- Threat Level: High. If bitten, seek immediate medical attention.
Funnel-Web Spiders (Atrax robustus & relatives)
While the Sydney Funnel-web is not native to the Gold Coast, several other species of funnel-web spiders are found here. They should all be treated with extreme caution.
- Identification: Large, dark, heavily-built spiders from black to brown. They have a shiny, almost glossy carapace (the front part of their body). They build silk-lined burrows in the ground, often with trip-lines radiating from the entrance.
- Threat Level: High. Any bite from a large, dark spider of this type should be treated as a medical emergency.
The Harmless (But Scary) Ones
Huntsman Spider (Sparassidae family)
This is the spider most likely to cause a fright by appearing on a wall inside your home.
- Identification: Large, fast-moving, and typically grey or brown with flattened bodies. They are known for their long, hairy legs that are spread out to the sides. They do not build webs to catch prey.
- Threat Level: Very Low. Despite their intimidating size, they are timid and reluctant to bite. They are more likely to run away. They are excellent at controlling cockroaches.
Golden Orb Weaver (Nephila species)
These are the master architects of the spider world, often found in gardens.
- Identification: Known for their huge, impressive webs of golden-coloured silk that can span several metres between trees. The female is large with a long body and banded legs. The male is tiny and often found in the same web.
- Threat Level: Very Low. They are not aggressive, and their venom is not considered dangerous to humans.
What to Do When You Find a Spider
- Don’t Panic: Most spiders are harmless. Keep children and pets away from the area.
- Don’t Handle It: Never attempt to catch or handle a spider unless you are 100% certain it is not dangerous.
- The “Glass and Card” Method: For common spiders like Huntsmans, you can safely place a glass or container over them, slide a piece of stiff card underneath, and release them outside.
For more detailed identification resources, the Queensland Museum provides an excellent online guide to local species.

Frequently Asked Questions
What is the most common spider on the Gold Coast?
The Huntsman spider is arguably the most commonly encountered spider inside homes. In gardens, the Golden Orb Weaver is extremely common.
Are huntsman spiders friendly?
While not “friendly,” Huntsman spiders are not aggressive. They are very timid and will almost always flee rather than bite. A bite would only typically occur if they were being handled roughly or were trapped against your skin.
How do I keep spiders out of my house?
The best methods are to seal up cracks and gaps around windows and doors, ensure your fly screens are in good repair, and reduce outdoor lighting at night, which attracts the insects that spiders feed on. A professional pest control barrier is the most effective long-term solution.
Summary: Spider Identification Gold Coast Checklist
✓ Identify: Look at the spider’s shape, colour, and web. Is it a black, velvety spider with a red stripe (Redback), or a large, flat, grey spider on your wall (Huntsman)?
✓ Assess the Risk: Is it in a high-traffic area? Is it a species known to be dangerous?
✓ Act Safely: Do not handle spiders you can’t identify. Use the “glass and card” method for relocation of harmless spiders.
✓ Consider Prevention: Trim back vegetation from the house and seal entry points.
✓ Call a Professional: For peace of mind and to manage a large or dangerous population, contact Pesties.au for a professional spider treatment.
