How to Get Rid of Spiders in Sydney
Getting rid of spiders takes two things: removing the food and shelter that attract them, and laying down a residual barrier treatment that keeps working for months. This guide covers how to identify Sydney species, what DIY can and cannot do, and the professional treatment that fixes the root cause.
The Short Answer on Getting Rid of Spiders
Squashing spiders one by one and knocking down webs will lower how many you see, but it will not clear the problem, because new spiders keep arriving to hunt the insects around your home. What actually gets rid of spiders is a residual barrier treatment that leaves a long-lasting layer on the surfaces they walk across, combined with cutting off the food and shelter that drew them in.
So the honest answer to "does pest control kill spiders" is yes, a professional residual treatment does, and it keeps working for months in a way that a can of surface spray cannot.
Step 1: Confirm You Have Spiders
Redback
Glossy black with a red stripe on the abdomen. Hides in dry, sheltered spots such as letterboxes, under outdoor furniture and in shed corners. A dangerous bite, so treat sightings seriously.
Funnel-Web
Large, dark and aggressive, favouring moist burrows in garden beds and under logs. One of the most venomous spiders in the world and a genuine emergency if it bites.
White-Tail
Slim, dark grey with a pale tip on the tail. A roaming hunter that wanders indoors and shelters in clothing and bedding, delivering a painful bite.
Black House & Huntsman
Black house spiders spin messy webs around window frames and eaves; huntsmans are large, fast and mostly harmless, turning up on walls and behind curtains.
Before you treat anything, work out what you are dealing with, because a harmless huntsman on the wall and a redback in the letterbox call for very different urgency. Check the usual hiding places: under the eaves, along fence lines, inside the letterbox, in the shed, under outdoor furniture and around window frames. Webs strung across corners, egg sacs tucked in sheltered spots and spiders active after dark all confirm a resident population rather than a one-off visitor.
If you find a redback or suspect a funnel-web, keep children and pets clear of the area and arrange treatment promptly. Our guide on whether spiders are dangerous explains which Sydney species warrant real caution.
Step 2: Remove What Attracts Them
Spiders follow their food, so the single most useful thing you can do is reduce the insects they hunt. Swap white outdoor globes for warm or yellow-toned lighting, which draws far fewer moths and midges to the walls at night, and keep lights off when they are not needed.
Then take away the shelter. Clear leaf litter, timber piles and clutter from against the house, trim shrubs so they do not touch the walls, and keep the garage and shed tidy so there are fewer dark corners to hide in. Sweep away webs and egg sacs as you find them, seal gaps around windows, doors and vents, and keep the garden perimeter tidy. None of this eradicates a population on its own, but it makes your home far less inviting and helps any treatment last longer.
What DIY Methods Can and Cannot Do
Retail products have their place, but it is a limited one. A supermarket surface spray kills the spider it lands on and little else, since it dries out quickly and leaves no lasting barrier on the surfaces spiders travel. Within a week or two, fresh arrivals move straight back in.
Home remedies such as peppermint oil, vinegar or conkers are popular online, yet there is no reliable evidence they clear an infestation. At best they briefly discourage a spider from one spot. Foggers and bombs are worse than useless for spiders, as the mist rarely reaches the sheltered cracks where they actually sit.
DIY can genuinely help with prevention, tidying, sealing gaps, adjusting lighting and removing webs, and it is fine for the occasional harmless spider. What it cannot do is deliver the long-lasting, professionally applied barrier that stops spiders returning, or safely handle a redback or funnel-web problem.
Step 3: Professional Treatment That Works
A professional treatment fixes the root cause rather than the symptom. The technician applies a residual product to the surfaces spiders walk across, the eaves, window frames, fences, doorways and other harbourage, so any spider crossing that treated zone picks up a dose and dies over the following days. Because the product stays active for months, it keeps clearing new arrivals long after the visit, which is the part DIY simply cannot match.
Accessible webs and egg sacs are knocked down and removed as part of the job, and indoor hotspots such as garages, subfloors and roof voids are treated where redbacks or white-tails are active. A licensed NSW technician carries out the work, and the products chosen stay gentle on children and pets while remaining tough on the spiders themselves.

Keeping Them Gone
Once the treatment has done its work, a few habits keep the property clear through the warmer months. Do a quick web sweep of the eaves and corners every couple of weeks, keep outdoor lighting warm-toned and switched off when not needed, and hose down the exterior now and then to remove dust and the tiny insects spiders feed on.
Keep the garden perimeter open, with shrubs trimmed back from the walls and firewood stored away from the house, and re-seal any new gaps that appear around windows and doors. For homes near bushland or reserves, where pressure is highest, a scheduled treatment through spring and summer keeps the barrier fresh. Our dedicated advice on how to prevent spiders goes deeper on year-round habits, and the full menu of treatments sits on our Sydney pest control services page.
When to Call a Professional
Some situations should go straight to a licensed technician rather than a spray can. Call if you find redbacks or a funnel-web anywhere near living or play areas, if spiders keep returning no matter how often you clear the webs, if you are seeing egg sacs and multiple spiders indoors, or if someone in the home is anxious about a bite. In each case the fast, safe fix is a professional barrier treatment that deals with the whole property at once.
Getting rid of spiders is a mix of tidying up their food and shelter and laying down a treatment that keeps working after you finish. Do the groundwork yourself, then let a licensed technician handle the barrier and the dangerous species, and your home stays clear well into the season.
