Nobody loves finding a big huntsman on the wall, or spotting a redback in the letterbox a second too late. If you live in Canberra, you know spiders come with the area. The suburbs sit right next to bushland, so they’re bound to turn up.
The good news? You don’t have to just put up with them. With a bit of prevention and the right treatment, seeing a spider can become a rare thing. Let’s go through it: what they are, why they show up, how to deal with them, and when it’s time to call a pro for spider control in Canberra.
Two Types of Spiders: Web-Builders and Runners
Canberra’s spiders fall into two main groups, and each one needs a different approach.
Web-building spiders sit in their webs and stay put. These are your redbacks, black house spiders, and the garden webs you sometimes walk into. Because they don’t move much, they’re easier to treat.
Running spiders are the ones that move around, like huntsmen, white-tails, and wolf spiders. They roam looking for food and dark places to hide, which makes them harder to target.
Funnel-webs are a bit of both. They live in burrows in the ground, but in autumn the males wander off looking for a mate, so we treat them like runners.
Once you know which type you’ve got, you’re already on the right track.
Common Spiders You’ll See in Canberra
Most spiders are harmless, and many even help by eating flies, mozzies, and cockroaches. But a few spiders with venom are worth watching out for:
- Redback – Black with a red stripe. The female’s bite can be serious, but there is antivenom. Likes dry, hidden spots like sheds, letterboxes, and rockeries.
- White-tailed spider – Slim, with a pale tip on its back. The bite hurts, but the “flesh-eating” story you may have heard isn’t true.
- Funnel-web – Not common here, but sometimes arrives in firewood or timber from the coast. A bite is a medical emergency, so get help straight away.
- Huntsman – Big and fast, which makes it scary, but it’s shy and would rather run than bite.
- Black house spider – Builds messy webs around windows and eaves. The bite hurts but isn’t deadly.
- Mouse and wolf spiders – Live on the ground and have a painful bite.
One simple rule: if you’re not sure what you’re looking at, don’t touch it. Leave it to someone who knows.
How to Know If You Have an Infestation
One or two spiders is normal. But a real spider infestation in Canberra usually shows a few clear signs:
- Webs building up around eaves, windows, corners, and fences.
- Small white egg sacs in more than one spot. Each one can hatch hundreds of baby spiders.
- Seeing the same kind of spider again and again, week after week.
- More activity in autumn, when spiders come inside for warmth, and through the warmer months.
A good rule: lots of web spiders means lots of insects for them to eat, and that food is exactly what brings the runners inside too. If you’re seeing several of these signs, it’s worth booking a professional spider inspection before it gets worse.
How to Keep Spiders Out
Stopping spiders before they settle in is much easier than getting rid of them later. A few things help:
- Keep garden beds and mulch back from the walls, and trim plants so they don’t touch the house.
- Keep clothes and shoes off the floor. Runners love hiding in a pile of washing or an old shoe.
- Clear the clutter in the garage, shed, or basement. Boxes and woodpiles against the house are perfect spider hideouts.
- Seal gaps around doors, windows, vents, and pipes. Weather strips under doors help too.
- Cut back on outdoor lights, or use warm-toned globes. Bright lights attract insects, and insects attract spiders.
How to Get Rid of Spiders
If they’re already inside, here’s what works:
- Treat the web spiders where they live. Spray the webs and their hiding spots. Then wait a day or two before brushing the webs away. This gives the spider time to walk across the spray and pick up a proper dose. Brush the webs off instead of hosing them, so the spray stays put and keeps working.
- Cover the sheltered spots. Spray around doors, windows, vents, eaves, and guttering. These areas are protected from sun and rain, so the treatment can last for months.
- Starve the runners. Running spiders walk on the tips of their legs and often don’t pick up spray. The trick is to treat the web spiders and other insects instead. No food around means no reason for runners to come in.
- Vacuum up egg sacs. Quick and easy, and it stops the next batch before it hatches.
For a proper, whole-home result that lasts, though, a professional treatment is still your best bet.
When to Call a Professional
DIY works fine for the odd spider. But if the webs keep coming back, if egg sacs show up in a few rooms, or if you spot venomous spiders near where the kids play, it’s time to get help.
A pro will work out what species you have and where they’re nesting, then use the right treatment. They use sprays for web spiders and dust for burrowing ones like mouse and funnel-web spiders, and they can reach the eaves, subfloors, and wall cavities you shouldn’t be poking around in yourself.

Frequently Asked Questions
Are spiders insects? No, they’re arachnids. Spiders have two body parts and eight legs. Insects have three body parts and six legs.
Are Canberra spiders dangerous? Most aren’t. But redbacks, white-tails, and the odd funnel-web do carry venom. If a venomous one bites you, get medical help quickly.
Do supermarket sprays work on spiders? They help with the odd spider, but they rarely reach the nests or egg sacs. A professional treatment goes deeper and lasts longer.
What does a spider bite look like? Usually two small puncture marks close together, with some redness and swelling. How much depends on the spider, and on the person too. Everyone reacts a little differently.
When are spiders most active in Canberra? The warmer months, and again in autumn when they move indoors. That’s also when male funnel-webs go wandering.
Is professional spider treatment safe for kids and pets? Yes. Good providers use approved, low-toxicity products applied to Australian standards. Just keep the kids and pets off treated spots until everything’s dry.
