Spiders in Your Home? Some of Them Are More Dangerous Than You Think.
Most people can live with the odd daddy long-legs hanging in a corner. What they can’t live with is finding a redback under the outdoor furniture, a white-tailed spider in the bedroom, or a funnel-web in the garden where their kids play.
Melbourne has a surprisingly diverse spider population, and while plenty of local species are completely harmless, several are genuinely dangerous and they’re all around us. The problem is that most people can’t tell the difference between a harmless garden spider and something that warrants a trip to hospital. And honestly, why take that risk?
Spider populations tend to build up quietly. Webs in corners, egg sacs tucked behind outdoor furniture, burrows near retaining walls it can go from a handful of spiders to a full-blown infestation without anyone really noticing until someone gets a nasty surprise. Autumn is particularly bad in Melbourne as spiders move indoors searching for warmth, and spring sees populations spike as eggs hatch across gardens and subfloor areas.
At Melbourne 24×7 Pest Control, we treat spider problems across homes, businesses, and outdoor areas throughout Melbourne. We identify the species on your property, treat existing populations, and apply barrier protection that stops new spiders from taking up residence. We’re available 24 hours a day, 7 days a week including same-day callouts for anything urgent.
Spider Species We Commonly Treat in Melbourne
Understanding what’s on your property makes a real difference to how we treat it. Here’s what we regularly deal with across Melbourne:
Redback Spiders are one of Australia’s most recognised venomous spiders and they’re extremely common in Melbourne particularly in sheltered outdoor spots like under garden furniture, inside letterboxes, behind retaining walls, in garden sheds, and around children’s play equipment. Their venom causes intense and prolonged pain, and bites require medical attention. They’re not aggressive but will bite if disturbed or pressed against skin.
White-Tailed Spiders are hunters rather than web builders, which means they roam often ending up in bedrooms, bathrooms, and living areas. They’re regularly found in folded clothing, bed linen, and towels. Their bite causes a sharp burning pain and in some cases leads to localised skin irritation and ulceration.
Funnel-Web Spiders are found in Melbourne’s outer suburbs and surrounding bushland areas. They’re burrow-dwelling spiders that become highly aggressive when threatened, and their venom is genuinely life-threatening. If you’re seeing burrows with distinctive funnel-shaped webs in your garden, don’t investigate yourself call us.
Black House Spiders are the ones responsible for most of the thick, untidy webs you see around window frames, wall corners, roof eaves, and brick crevices. They’re not considered highly dangerous but their bites can cause pain, nausea, and sweating. They also attract redbacks, which prey on them.
Huntsman Spiders are big, fast, and terrifying to encounter unexpectedly but they’re generally not dangerous to humans. That said, most people would rather not share their home with a spider the size of their hand, and we completely understand that.
Wolf Spiders are ground-dwelling hunters that live in lawns, gardens, and leaf litter. They’re fast movers and can end up inside through gaps at ground level. Their bite is painful but not life-threatening for most healthy adults.
Garden Orb-Weaving Spiders build large, impressive webs overnight across paths, between shrubs, and around outdoor entertaining areas. They’re not dangerous but the webs are a constant nuisance and the spiders can give a painful bite if handled.
Why Spider Numbers Build Up Faster Than Most People Expect
Spiders follow their food source. If your property has a healthy insect population which most Melbourne homes do spiders have everything they need to thrive. Gardens with dense ground cover, properties near bushland or water, homes with outdoor lighting that attracts insects at night, and buildings with lots of external crevices and gaps all tend to have higher spider activity.
The other issue is that spiders reproduce in large numbers. A single egg sac can contain hundreds of spiderlings. Left undisturbed in a garden bed, under decking, or in a roof void, a handful of spiders becomes a significant population within a single season.
Over-the-counter spider sprays can knock down individual spiders you spray directly, but they don’t deal with egg sacs, they don’t treat harbourage areas properly, and they have no lasting effect on new spiders moving in from surrounding areas. Professional treatment applies residual products to the right surfaces and locations the places spiders walk across rather than just the ones where you can see them sitting.
How We Treat Spider Infestations
We start with a full inspection of the property inside and out. That means checking roof eaves, window frames, subfloor voids, garden beds, retaining walls, decking, outdoor furniture, letterboxes, and garden sheds. Spider activity tends to concentrate in predictable spots once you know what to look for, and identifying those harbouring zones is what makes the treatment effective.
From there we apply a residual spray to all external surfaces, entry points, and known activity areas. Spiders pick up the treatment as they move across treated surfaces it doesn’t require direct contact with the spray itself. We also treat subfloor voids and roof voids where accessible, as these are major harbouring areas that most DIY treatments never reach.
Where egg sacs are present, we remove and treat them directly. Leaving egg sacs in place after a surface treatment is one of the most common reasons spider numbers bounce back quickly after treatment.
We finish up with practical advice specific to your property things like reducing outdoor lighting that draws insects in at night, trimming vegetation away from the building, clearing clutter from garden sheds and under decking, and sealing the gaps that give ground-level spiders easy access indoors.
