To get rid of spiders in a Sydney home, you need to remove the webs, treat the eaves and roof void where they shelter, and clear the garden clutter that hides them. Spiders follow their food, so a home with lots of insects will always have lots of spiders. Professional spider control targets webs, egg sacs and hiding spots around the whole building. Priority Pest Services treats Sydney homes with a residual spray that keeps spiders out for up to 6 months, backed by a 6-Month Warranty*.

Why does my Sydney home keep getting spiders?
Because spiders follow insects. If your home has ants, flies, moths or other crawling insects, spiders will set up webs nearby to catch them. Sydney's warm climate and bushland edges make it ideal for hundreds of spider species. Leafy suburbs like the North Shore and the Northern Beaches have the highest spider pressure because of the dense tree cover and bushland. The spiders you see inside are almost always following a food source, a mate, or shelter from rain.
Which Sydney spiders are dangerous?
Most Sydney spiders are harmless and actually help by eating insects. But two species require real caution, and one is the most dangerous spider in the world.
| Spider | Where it hides | Risk level |
|---|---|---|
| Sydney funnel-web | Moist soil, leaf litter, under logs and rocks | Highly venomous - call 000 if bitten |
| Redback | Sheds, fences, outdoor furniture, weepholes | Venomous - seek medical help |
| Huntsman | Inside homes, behind pictures, in cars | Harmless but startling |
| Black house spider | Eaves, window frames, sheds | Low venom, painful bite |
| White-tail | Bark, leaf litter, sometimes indoors | Low risk, often misblamed |
Funnel-webs are most active on the Northern Beaches, the North Shore and in bushland suburbs near national parks. Male funnel-webs wander after rain on warm nights, often ending up in garages, pools and shoes. Redbacks prefer dry, sheltered spots like sheds, letterboxes and under outdoor furniture. If you are bitten by a funnel-web, apply a pressure bandage and call 000 immediately.
How do professionals get rid of spiders?
Professional spider control works by removing the webs and egg sacs, then treating the surfaces where spiders rest and rebuild. We treat the whole building envelope so spiders have nowhere to shelter.
- Inspect: We find where spiders are nesting inside and out, including the roof void and subfloor.
- Web removal: We brush down webs from eaves, windows, door frames and light fittings.
- Treat surfaces: We apply a residual spray to eaves, window frames, doors and fences where spiders rest.
- Dust the roof void: We apply insecticidal dust to the roof void where spiders and the insects they eat both shelter.
"Spiders follow food. Treat the insects and the spiders stop coming back."
How long does spider treatment last?
A professional spider treatment lasts up to 6 months on external surfaces, depending on weather exposure. Indoors, the residual effect can last up to 12 months because it is protected from UV light and rain. It is normal to see a few spiders in the days after treatment as they are driven out of hiding. Spider treatment is covered by our 6-Month Warranty* on internal infestations.
| Method | Removes webs | Kills spiders | How long it lasts |
|---|---|---|---|
| Broom or vacuum | Yes (temporary) | No | Days - webs rebuild fast |
| Surface spray from the shop | No | On contact only | 1 to 2 weeks |
| Professional treatment | Yes | Yes, plus egg sacs | Up to 6 months |
Key tips to keep spiders out of your home
- Clear garden clutter - remove leaf litter, timber offcuts and stored items where spiders and their prey shelter.
- Trim plants away from walls - branches touching the house act as bridges for spiders and insects.
- Shake out shoes and gloves left in garages or outside before putting them on.
- Keep bins closed - flies attracted to bins are the main food source for web-building spiders.
- Fix exterior lighting - warm lights attract the insects that spiders feed on. Use cooler, yellow-toned bulbs near entry points.
- Book an annual spider treatment - many homes book in early spring before the breeding season starts.

Frequently Asked Questions
How much does spider control cost in Sydney?
A professional spider treatment for a standard Sydney home starts at $200. It includes web removal, a residual spray to external surfaces and a roof void dust. It carries our 6-Month Warranty* on internal activity.
Do you treat funnel-web spiders?
Yes. We treat the moist, sheltered areas funnel-webs prefer, such as garden beds, rockeries, under decks and in leaf litter. If you are bitten by a funnel-web, apply a pressure bandage and call 000 straight away.
Is spider treatment safe for pets and kids?
Yes. Keep pets and children away from treated areas until the spray dries, which takes about 2 hours. Once dry, the product binds to the surface. Cover fish tanks with a towel, as the active ingredient is toxic to fish.
How often should I get spider treatment?
Most homes book once a year, often in early spring before spiders start breeding. Homes near bushland or with heavy spider pressure may benefit from treatment every 6 months. Treatment carries our 6-Month Warranty*.
Will the treatment kill the egg sacs?
Yes. We remove webs and egg sacs by hand where we can reach them, and the residual spray and roof void dust target any sacs and spiderlings we cannot see. This stops a new generation hatching inside your home.
