You reach into the garden shed for the rake. Your fingers close around something that isn’t the rake.
You pull back. There’s a small, glossy black spider with a red stripe clinging to the handle. Your heart rate doubles in about half a second.
Was it a Redback? Was it dangerous? Should you go to hospital? Was that thing about the flesh-eating white-tail actually true?
If you’ve ever had that moment — or the equally alarming experience of finding a huntsman the size of your hand sprinting across the bedroom wall at midnight — you know the particular dread that spiders bring into a Melbourne home.
The problem is, most of what Australians think they know about spiders is either exaggerated, completely wrong, or missing crucial detail. And that gap between fear and fact is exactly what stops people from knowing when to act and when to relax.
This guide covers every spider you’re likely to find in a south-east Melbourne home — what it looks like, where it hides, how dangerous it actually is, and what to do about it.
Suburbs like Cranbourne, Berwick, Dandenong, Springvale, Noble Park, and Keysborough are prime spider territory — and there are specific reasons why.
The green corridors running through Cranbourne, along the Cardinia Creek and the Dandenong Creek valley, support enormous insect populations year-round. Spiders follow their food supply — and where insects thrive, spiders multiply. The established gardens, mature trees, and leaf-littered reserves that make these suburbs so liveable are, from a spider’s perspective, a five-star resort.
The older housing stock across Springvale, Noble Park, and parts of Keysborough adds another factor. Homes built in the 1970s and 1980s tend to have more unsealed roof voids, cracked brickwork, aged weatherboards, and gap-prone eaves — all of which are excellent spider entry points.
And then there’s the autumn migration. As Melbourne’s temperatures drop through April and May, spiders that spent summer living outdoors start looking for somewhere warmer. Your wall cavity, garage, outdoor shed — and occasionally your kids’ bedroom — are exactly what they’re looking for.
Here is what you need to know about each species — in plain English, not pest-industry jargon.
How to identify it: Glossy black body, red or orange stripe on the upper abdomen. Female up to 10mm. Males are much smaller, light brown, and harmless. The web is messy and funnel-shaped, built close to the ground.
Where it hides: Under outdoor furniture, inside letterboxes, in garden pots, along metal fence rails, under children’s toys left on the grass, inside downlights and outdoor electrical fittings, in sheds and garages.
How dangerous is it? The Redback is the most medically significant spider commonly found in Melbourne homes. Its venom causes intense, progressive pain, sweating at the bite site, nausea, and dizziness. Symptoms can last 24 hours or more. However — no deaths have been recorded in Australia since antivenom was introduced in 1956. The antivenom is effective and available at all hospitals.
If bitten: Apply an ice pack. Do NOT use a pressure bandage. Go to emergency immediately. Call the Poisons Information Centre on 13 11 26.
How to identify it: Dark grey, elongated body with a distinctive white spot on the tip of the abdomen. 12 to 20mm long. No permanent web — it hunts at night.
Where it hides: Folded clothing, towels left on floors, under bedding, behind curtains, in bathrooms, laundries, and wardrobes. It wanders inside hunting other spiders, particularly black house spiders.
How dangerous is it? Far less dangerous than its reputation suggests. A comprehensive Australian study of 130 confirmed white-tail bites found not a single case of the flesh-eating ulcers the spider is famous for. Bites typically cause localised pain and redness, resolving within 24 hours. The necrotic ulcer reputation is based on misidentified bites and has been scientifically debunked.
If bitten: Apply an ice pack, wash the area with soap and water, and monitor for 24 hours. Seek medical attention if symptoms worsen. The main risk is being bitten in bed or when getting dressed — the spider is not aggressive, it just gets accidentally trapped against skin.
Best prevention: Shake out clothing, towels, and shoes before putting them on. It takes two seconds and eliminates most white-tail bite risk.
How to identify it: Large, flat, hairy. Brown or grey. Leg span up to 15cm. Moves very fast. Does not build a web — it hunts prey directly.
Where it hides: Behind wall hangings, under furniture, in roof voids, inside cars, under bark and in garden structures. Enters homes through eaves gaps, open windows, and from outdoor vegetation.
How dangerous is it? Despite being the spider most likely to make grown adults scream and leave a room, huntsmans are not dangerous to humans. Bites are rare — they prefer to flee — and cause only mild localised pain and occasional nausea. Their biggest real risk is when they appear unexpectedly in moving vehicles. Multiple car accidents across Australia have been attributed to huntsmans emerging from sun visors while driving.
The upside: Huntsmans actively hunt cockroaches, flies, moths, and other insects. A huntsman in your home is, ecologically speaking, working for you. If you can tolerate its presence, consider letting it be.

How to identify it: Dark brown to black, robust body up to 18mm. Builds messy lace-like webs in corners, around window frames, eaves, and on outside walls.
Where it hides: Window frames, eaves, corners of rooms, outside brick walls, bark and rock crevices. Webs become very visible when left untreated — an indicator of growing activity.
How dangerous is it? Bites can cause localised pain, swelling, and occasional nausea, but are not considered dangerous to healthy adults. Their main issue is that web numbers multiply quickly, which indicates a growing population and an active prey insect supply in the home.
How to identify it: Brown, grey, or black with patterned markings. 8 eyes arranged in a distinctive three-row formation. Does not build a web. Fast-moving, ground-dwelling.
Where it hides: Lawns, garden beds, leaf litter, under rocks, in garages and under doors. Occasionally enters homes but prefers outdoor ground-level environments.
How dangerous is it? Bite causes mild localised pain, usually only occurs if the spider is accidentally stood on or picked up. Active across Berwick, Beaconsfield, Devon Meadows, and Langwarrin properties with large gardens.
How to identify it: Tiny, pale body with extremely long, thin legs. Builds fine, tangled webs in ceiling corners, garages, and sheds.
How dangerous is it? Not at all. The ‘world’s most venomous spider’ myth about daddy long legs is completely false and has been thoroughly tested. Their venom is almost entirely harmless to humans. Better still — they actively catch and eat Redback spiders. A corner full of daddy long legs webs is doing your home a service.
Most Melbourne households have a can of spider spray under the sink. Most of those same households still have spiders.
The problem isn’t the spray itself — it’s what it can and cannot do. A contact insecticide kills any spider it lands on, but it evaporates quickly and leaves no residual protection. More importantly, it does nothing about the three things that actually drive spider populations in your home:
Professional spider control is a whole-property approach, not just a spray. Here is how Abby’s handles a spider job:

Symptoms: Intense, spreading pain. Sweating at the bite site (characteristic sign). Nausea and vomiting. Headache and dizziness.
First Aid: Apply an ice pack only. Do NOT apply a pressure bandage. Go to emergency immediately. Antivenom is available and effective at all Australian hospitals.
Symptoms: Localised pain and redness. Mild swelling. Itching. Occasional nausea.
First Aid: Apply an ice pack. Wash the bite area with soap and water. Monitor for 24 hours. Seek medical attention if symptoms worsen. The flesh-eating myth is false — do not panic.
Symptoms: Mild localised pain. Minor swelling. Very occasionally nausea or headache.
First Aid: Apply an ice pack and rest. Seek medical attention if symptoms escalate. Bites are uncommon — huntsmans prefer to flee.
If you could not identify the spider: Stay calm. Catch the spider safely if possible to assist with identification. Apply a pressure immobilisation bandage only if a funnel-web or mouse spider bite is suspected. Go to emergency. Do not squeeze the bite site.

Yes — very. Redbacks thrive in suburban gardens, sheds, letterboxes, under outdoor furniture, and along fences across Cranbourne, Berwick, Beaconsfield, and Devon Meadows. The established gardens and green corridors in these suburbs are ideal habitat. If you have a garden, you almost certainly have Redbacks nearby.
No. This is one of Australia’s most persistent urban myths. A comprehensive Australian study of 130 confirmed white-tailed spider bites found not a single case of necrotic ulceration. Bites cause localised pain and redness, similar to a bee sting. Uncomfortable — but not flesh-eating.
Not about your safety — huntsmans are not dangerous to humans and actually hunt cockroaches and other insects in your home. If the sight of it is too much, call Abby’s for a safe same-day removal across Dandenong and surrounding suburbs on 0431 270 152.
Professional spider treatments provide 3 to 6 months of residual protection. Given the density of established housing and gardens in Springvale and Noble Park, we recommend treatment every 6 months — ideally in spring and autumn when spider activity peaks.
Over-the-counter sprays only kill spiders they contact directly — they do not treat egg sacs or address the underlying insect population that feeds spiders. Professional treatment uses residual products that work for months and targets the whole population, not just the spiders you can see.
Yes. Abby’s Pest Control covers all south-east Melbourne suburbs including Rowville, Heatherton, Mulgrave, Lyndhurst, Lynbrook, and Langwarrin. Call 0431 270 152 for same-day service or a free quote.
Autumn (March to May) is the most important time — spiders are moving indoors as temperatures drop. Spring (September to October) is the second peak, as egg sacs hatch and populations grow. Treating in early autumn, before spiders settle in for winter, gives you the best year-round protection.
