Spider Control in Melbourne
Melbourne homes share their walls, eaves, and gardens with a wide range of spiders through the warmer months. Most are harmless nuisance species that build webs around windows and fences, but a handful — the redback in particular — carry a genuine bite risk that makes hands-off tolerance a poor idea when children and pets are around.
Protech has been treating spiders across Melbourne since 2001. Our licensed technicians identify what is actually present at your property, clear the existing webs and egg sacs, and apply a residual barrier that keeps working for weeks after we leave. The result is fewer webs to walk into, fewer redbacks tucked into the shed, and a home that stays clear through the busy spring and summer season.
If you have spotted webs building up, found a redback outdoors, or keep meeting huntsman spiders on the wall, call us on 03 9449 4244 for same-day service and a pest-free guarantee.
Dangerous Spiders vs Nuisance Spiders in Melbourne
Knowing which spider you are dealing with changes how seriously to take it. Of the spiders that turn up around Melbourne homes, only two groups carry a real medical concern, and the rest are best treated as a nuisance that fouls windows and unsettles the household.
The redback — the one that matters
The redback is the spider of genuine concern in suburban Melbourne. Only the female's bite is medically significant, and according to the Better Health Channel it may require antivenom. Bites bring intense local pain that increases and spreads, along with sweating, headache, and muscle weakness. Redbacks favour dry, sheltered outdoor spots — under garden furniture, inside letterboxes and meter boxes, beneath the rims of pots, and around sheds — which puts them exactly where hands reach without looking.
The Victorian funnel-web — outer fringes only
A native funnel-web (Hadronyche modesta) lives in the wetter forested edges of Melbourne such as the Dandenong Ranges, and its bite is treated as medically significant. It is far less aggressive than its Sydney relative, and the Better Health Channel confirms the dangerous Sydney funnel-web does not occur in Victoria at all. Typical inner and middle-suburban gardens rarely see funnel-webs.
White-tailed, black house, huntsman and wolf spiders — nuisance biters
These species can bite and cause local pain and swelling, and they are the ones most people actually encounter indoors and around the yard. The white-tailed spider has long been blamed for skin ulcers, yet the Better Health Channel notes that medical studies have not been able to confirm any link between its bite and necrosis. Huntsman spiders, despite their size, are described as usually harmless. The health value in treating these species is mostly peace of mind and a home free of webs and egg sacs, rather than removing a serious danger.
Common Spiders in Melbourne Homes
These are the species Protech technicians identify most often across Melbourne's suburbs, from redbacks in the shed to huntsman spiders behind the sun visor. For deeper identification detail and biology, see our cited spider identification guide in the Pest Library.
Redback Spider
The one Melbourne spider most people worry about, and reasonably so. The female is a glossy black spider around a centimetre across the body with the familiar red or orange stripe down the back of the abdomen. She spins a messy, tangled web low to the ground and favours dry, sheltered spots — under outdoor furniture, inside letterboxes, in the folds of tarpaulins, beneath the rim of pot plants, and around sheds and garages. Only the female's bite is medically significant, and it is a common reason for antivenom use in Victoria.
White-tailed Spider
A slender, dark grey to reddish spider with a distinctive pale marking at the tip of the abdomen and a cigar-shaped body around 12 to 18 mm long. It does not build a web to catch prey. Instead it roams at night hunting other spiders — black house spiders in particular — which is why it turns up indoors, in bedding, in clothing left on the floor, and along skirting boards. Its bite causes local pain and swelling.
Black House Spider
A shy, robust dark spider that builds a lacy, funnel-shaped web with a distinctive entrance tunnel. You will find these webs in the corners of window frames, in the gaps between bricks, on fences, around external lighting, and under eaves. They rarely leave the web and account for much of the untidy webbing that builds up around a Melbourne home over spring and summer. Their presence also draws in white-tailed spiders that prey on them.
Huntsman Spider
Large, flat, fast, and alarming to find on a wall or ceiling, though largely harmless. Huntsman spiders are grey to brown with long legs that let them sit flush against timber and slip into narrow gaps. They wander indoors through open windows and roof voids, and famously appear behind sun visors in parked cars. A bite may cause brief pain and swelling and little more, but their size makes them one of the most frequent callouts we get.
Wolf Spider
A ground-dwelling hunter with a mottled grey, brown, and yellow body that provides good camouflage on soil and lawn. Wolf spiders do not spin a snare web; they chase prey across the ground and shelter in burrows or under leaf litter, timber, and garden debris. They are common in Melbourne gardens and around the edges of lawns, and occasionally move indoors through ground-level gaps, particularly after heavy rain.
Funnel-web Spider
The Victorian funnel-web (Hadronyche modesta) occurs in the wetter, forested fringes of Melbourne such as the Dandenong Ranges rather than in typical suburban gardens. It is a dark, heavy-bodied ground spider that shelters in burrows in moist soil. The far more dangerous Sydney funnel-web is not found in Victoria at all. A Victorian funnel-web bite is still treated as medically significant and warrants prompt medical attention.
Signs of a Spider Problem
Spiders are easier to spot than most household pests, but the early signs of a building population are easy to write off as ordinary. These are the indicators worth acting on:
Webs and funnel entrances
Fresh webbing that keeps reappearing after you clear it points to an established population. Black house spiders leave lacy webs with a funnel-shaped entrance in window corners, brickwork gaps, and around external lights, while orb-weavers string large round webs across paths and between shrubs overnight.
Egg sacs
Silken egg sacs are the clearest warning that numbers are about to climb. A single sac can hold well over a hundred spiderlings, and the female often guards it or fixes it to the web or a sheltered surface. Redback egg sacs are round, papery, and cream-coloured, tucked deep in the messy web.
Spiders indoors
Finding huntsman spiders on walls and ceilings, or white-tailed spiders in bedding and clothing left on the floor, means spiders are moving through the home. White-tails in particular follow their prey indoors, so their presence usually means black house spiders are nearby.
Plenty of other insects
Spiders go where the food is. A steady supply of flies, moths, and other insects around outdoor lighting or inside the roof void will support a growing spider population, so a rise in general insect activity often precedes a rise in spiders.
Our Spider Treatment Method
Effective spider control comes down to treating the places spiders harbour and creating a lasting external barrier at the source. Our technicians follow a consistent process built around the way each type of spider actually lives.
- Inspection and identification: We work through the property inside and out, identify the species present, and locate the harbourage points — eaves, weep holes, fence lines, sheds, garden edges, and roof voids — that drive the population.
- Web and egg-sac removal: Existing webs and egg sacs are knocked down and cleared by hand, which removes the current generation and lets us see quickly whether the treatment is holding at the follow-up.
- Residual perimeter spray: A residual surface treatment is applied to the external perimeter and known harbourage — around windows, eaves, doorframes, weep holes, and fencing. Spiders pick up the treatment as they cross these surfaces, so the barrier keeps working for weeks after we leave.
- Targeting the hunters: Nomadic spiders such as huntsman and white-tailed spiders never sit on a sprayable web, so we manage them by treating their harbourage and reducing the black house spiders and insects they feed on, rather than blanket spraying open ground.
- Prevention advice and follow-up: We point out the entry points and conditions drawing spiders in, and set a follow-up schedule where pressure is high — commonly a spring treatment with a summer top-up.

Spider Season in Melbourne
Spider activity in Melbourne follows the warmth. Numbers climb through spring and peak across summer, roughly October to February, as breeding accelerates and the insects spiders feed on become abundant. This is when webbing builds up fastest around eaves and windows and when redbacks fill sheltered outdoor spots in the garden and shed.
Autumn brings a second flush of activity as mature males wander in search of a mate and females lay their egg sacs, which is when many people first notice large spiders moving indoors. Through the cooler months spiders slow down and shelter, and some overwinter until the following spring.
The practical upshot is timing. A treatment applied at the start of spring puts the residual barrier in place before the population takes off, giving the longest run of protection through the busiest part of the year. Homes backing onto reserves, creeks, or bushland tend to face higher pressure and benefit from a summer top-up.
How to Keep Spiders Away
Professional treatment does the heavy lifting, and a few habits around the home keep pressure down between visits:
- Clear webs and egg sacs as they appear, especially around window frames, eaves, and external lighting.
- Swap bright white outdoor globes for warm or yellow lighting, which draws in fewer of the insects spiders feed on.
- Cut back branches, shrubs, and climbing plants that touch the walls and give spiders a bridge indoors.
- Seal gaps and cracks around doors, windows, weep holes, and service penetrations, and fit or repair door and window screens.
- Reduce clutter and garden debris — timber stacks, leaf litter, and stored boxes against the house all make ideal harbourage.
- Shake out shoes, gloves, and clothing that has been left on the floor or stored in the garage before putting them on.
- Keep sheds, garages, and subfloor areas tidy and check them regularly, since these are prime redback territory.
Damp, poorly ventilated subfloors also attract the insects that feed spiders. If your home has a musty or moisture-prone underfloor, improving airflow with subfloor ventilation reduces the conditions spiders and their prey rely on.

Frequently Asked Questions
Which spiders in Melbourne are actually dangerous?
The redback is the spider of genuine medical concern in suburban Melbourne — only the female's bite is dangerous, and it is a common reason for antivenom in Victoria. The Victorian funnel-web found in the outer forested fringes is also treated as medically significant, though the far more dangerous Sydney funnel-web does not occur in Victoria. White-tailed, black house, huntsman, and wolf spiders can bite and cause local pain and swelling, but they are best described as a nuisance rather than a serious health risk. According to the Better Health Channel, the historical link between white-tailed spiders and skin necrosis has not been confirmed by medical studies.
What does professional spider control actually involve?
A Protech technician inspects the property inside and out, identifies the species present, and knocks down and removes existing webs and egg sacs by hand. We then apply a residual surface spray to the external perimeter — around window frames, eaves, weep holes, fence lines, and other harbourage points — which continues working for weeks as spiders walk across the treated surfaces. For web-building species this is highly effective. Nomadic hunters like huntsman and white-tailed spiders are managed by targeting their harbourage and reducing the black house spiders they feed on, rather than by blanket spraying open ground.
When are spiders worst in Melbourne?
Spider activity climbs sharply through spring and peaks over summer, from roughly October to February, as warmth drives breeding and the insects they feed on become abundant. This is when webs build up quickly around eaves and windows and when redback numbers rise in sheltered outdoor spots. Autumn brings a second flush as males wander in search of a mate and egg sacs are laid. A treatment going into spring gives the longest protection through the busiest months.
How long does a spider treatment last?
A professional external treatment typically keeps webbing spiders under control for several months, with the residual barrier gradually breaking down through weather and UV. Most Melbourne homes do well with a treatment at the start of spring and, where pressure is high, a follow-up over summer. Protech will recommend a schedule based on your property, the species present, and how exposed the building is to surrounding gardens and bushland.
Are the treatments safe for children and pets?
Yes. Protech uses products applied at label rates by licensed technicians, with treatment focused on external harbourage and web zones rather than living areas. Your technician will let you know if any surface needs a short time to dry and will advise on any brief access restrictions. We hold HACCP, NPMA, and AEPMA accreditation and have been treating Melbourne homes since 2001.
Can I get rid of spiders myself?
You can reduce numbers by removing webs regularly, clearing clutter and garden debris against the house, sealing gaps around doors and windows, and swapping bright white external globes for warm or yellow ones that draw fewer insects. Supermarket sprays kill spiders on direct contact but leave no lasting barrier and do little for redbacks tucked into sheltered spots or hunters that never touch a treated web. A professional residual treatment is what keeps numbers down through the season.
