What is a wolf spider?
TL;DR — Quick Answer
Wolf spiders are ground-hunting spiders from the Lycosidae family. Unlike web-building spiders, they actively chase or ambush their prey and usually live in gardens, lawns, leaf litter and burrows. They are common across Australia and generally avoid humans, but may bite if threatened or handled.
How Do I Know If It’s a Wolf Spider?
That big hairy spider you saw — especially if dozens of tiny babies scattered from its back — is almost certainly a wolf spider. Check these key features:
- Up to 35mm body length; leg span can reach 70mm
- Colours: brown, black, grey or orange with camouflage patterns
- 8 eyes total — 2 very large central eyes give them excellent night vision
- Robust, hairy body and strong, prominent fangs
- Females carry white egg sacs then hatchlings on their abdomen
There are over 200 known wolf spider species across Australia, with many common throughout Greater Sydney. Their camouflage makes them almost invisible against soil, leaf litter or paving — until they move.

Where Do Wolf Spiders Live Around Sydney Homes?
Wolf spiders are ground‑dwellers found worldwide — and right in your own backyard. They do not build webs to catch food.
Common outdoor spots include:
- Silk‑lined burrows in soil or under paving
- Piles of leaves, mulch, rocks, firewood and garden debris
- Long grass and dense low vegetation near walls
When they move indoors, they usually stay near ground level — garages, doorways, window sills, subfloors and basements. They enter for warmth, shelter or to hunt insects drawn to lights.
How Do Wolf Spiders Hunt and What Do They Eat?
These are active nocturnal hunters — they stalk, chase and pounce on prey like wolves, hence their name.
- Excellent night vision and very fast over short distances
- Ambush or chase insects, other spiders, and small invertebrates
- Large females can even eat tiny frogs, skinks and geckos
- They grip prey with strong legs then inject venom to subdue it
Research from the Australian Museum shows wolf spiders help control pest insects like flies, aphids and cockroaches — making them beneficial in gardens.
Are Wolf Spiders Dangerous to Humans in Sydney?
They are not aggressive and would rather flee than fight. Bites happen only if you accidentally squeeze, trap or handle them.
Their venom is not lethal to humans. Typical bite effects:
- Local redness, mild swelling and itchiness
- Short‑term pain similar to a bee sting
- Very rarely: mild nausea or headache in sensitive people
One exception: a mother separated from her babies may be more defensive and stand her ground — but even then, she will not chase you.
First aid: wash the area with soap and water, apply a cold pack, and see a doctor if symptoms worsen or you have known allergies. This follows NSW Health guidelines.
How Can You Deter Wolf Spiders From Your Property?
Make your yard and home less attractive by removing what they need most:
- Clear leaf litter, firewood piles, rocks and debris away from walls
- Keep lawn short and trim bushes back from the house
- Seal cracks in foundations, skirting boards and around pipes
- Fit insect screens to doors, windows and vents
- Reduce outdoor lighting at night — it draws the insects they hunt

Frequently Asked Questions
Why do wolf spiders carry their babies on their back?
After hatching, spiderlings climb onto mum’s abdomen for protection and moisture. They stay there until big enough to hunt alone — usually 1–2 weeks.
Do wolf spiders jump at you?
No — they jump only to catch prey or escape. They do not leap toward people intentionally.
Can wolf spiders climb walls or beds?
They are poor climbers on smooth surfaces but can grip rough textures. They rarely climb high; they prefer staying close to the ground.
How do I tell a wolf spider from a funnel‑web?
Wolf spiders have a distinct camouflage pattern and two huge central eyes. Funnel‑webs are shiny black with larger, downward‑pointing fangs — if unsure, keep your distance and call professionals.
