How to Get Rid of Spiders in Adelaide

Spiders are Australia’s most common household pest concern—and for good reason. With over 3,000 spider species in Australia, including some of the world’s most venomous, it’s natural to want them out of your home.

The good news? Most spiders are harmless, and many are actually beneficial predators that help control other insect populations. But if spiders are making you uncomfortable, or you’ve spotted concerning species, here’s everything you need to know about getting rid of spiders in your Adelaide home.

Understanding Adelaide’s Spiders: Which Ones Matter?

Common Household Spiders in Adelaide

Spider Type	Risk Level	What to Know
Huntsman spiders	Low (non-venomous to humans)	Large, fast, intimidating but harmless. Common in Adelaide homes.
Orb-weaver spiders	Very low	Build distinctive webs. Harmless to humans.
Daddy long-legs / cellar spiders	Very low	Harmless, often found in corners.
Redback spiders	Moderate (venomous)	Recognisable by red stripe on back. Bites painful but rarely serious with treatment.
White-tail spiders	Low-moderate	Recognisable by white tip on abdomen. Bites can be painful.
Funnel-web spiders	High (venomous)	NOT found in Adelaide—they’re restricted to eastern NSW/QLD.

Important: If you’re in Adelaide, you don’t need to worry about funnel-web spiders. They don’t occur in South Australia.

Which Spiders Should Concern You?

The main spiders that warrant attention in Adelaide:

1. Redback spiders — Venomous, found in sheltered areas (sheds, debris, under furniture, mailboxes). Recognisable by the red/orange stripe on the female’s back.

1. White-tail spiders — Venomous but bites rarely cause serious issues. Greyish with a white tip on the abdomen. Often found hunting other spiders at night.

1. Large huntsman spiders indoors — Not dangerous but understandably alarming. They enter homes seeking prey or shelter.

How to Get Rid of Spiders Naturally

For minor spider problems, these methods can help:

1. Remove Webs and Egg Sacs

Use a broom or vacuum to remove webs, paying attention to corners, behind furniture, and in sheds/garages. Destroy any egg sacs you find (small, silken balls). This removes current spiders and prevents new generations.

2. Reduce Outside Lighting

Lights attract insects, which attract spiders. Switch exterior lights to motion-sensor or yellow-light bulbs (less attractive to insects). Keep windows screened when lights are on.

3. Declutter and Clean

Spiders hide in clutter. Reduce storage piles, cardboard boxes, and piles of clothing. Regular vacuuming removes spiders, webs, and the insects spiders eat.

4. Seal Entry Points

Check for gaps around windows, doors, pipes, and vents. Seal with caulk, weather-stripping, or mesh. This reduces spider entry.

5. Reduce Other Insects

Spiders follow their food source. Reducing flies, mosquitoes, and other insects reduces spider attraction. Keep food sealed, clean up crumbs, manage waste, and reduce moisture.

6. Natural Repellents (Limited Effectiveness)

Some people report success with:

• Peppermint oil spray: Mix peppermint essential oil with water and spray around entry points. Theoretically repulsive to spiders, but scientific evidence is limited.
• Vinegar spray: Equal parts vinegar and water sprayed in corners and entry points.

Realistic expectation: Natural methods may help reduce spiders somewhat, but they’re not as effective as professional treatment for established problems.

How to Get Rid of Spiders Fast: Direct Removal

Catch and Release (Humane Method)

1. Get a clear container (glass or plastic cup)
2. Place it over the spider
3. Slide a piece of paper/card underneath
4. Carry the spider outside and release

This works well for individual spiders and doesn’t harm them. For large huntsman spiders, this is often the preferred approach—they’re harmless and can be returned to the garden.

Vacuum Removal

Use a vacuum with a hose attachment to remove spiders, webs, and egg sacs. Empty the vacuum canister or dispose of the bag afterward to prevent spiders from returning.

Professional Spider Control: When and How It Works

For persistent spider problems, professional spider treatment is the most effective solution.

What Professional Spider Treatment Includes:

1. Inspection: Identifying spider types, activity areas, and potential entry points
2. Interior treatment: Application of residual insecticide to walls, corners, behind furniture, under benches, around windows, and other spider harbourages
3. Exterior treatment: Treatment of foundations, eaves, window frames, pergolas, garden edges, and other exterior areas where spiders dwell and enter
4. Webbing removal: Physical removal of webs where practical
5. Advice: Recommendations for reducing spider attraction and entry

How Professional Spider Treatment Works:

Professional spider sprays use residual insecticides that remain effective for weeks after application. When spiders crawl over treated surfaces, they absorb the insecticide through their legs and are eliminated.

Key advantage: Unlike DIY products that only kill spiders you spray directly, professional treatment creates a lasting barrier that kills spiders over time as they contact treated surfaces.

How Long Does Spider Treatment Last?

A professional spider treatment typically remains effective for 2-3 months, depending on products used, weather conditions, spider pressure, and prevention measures.

Most Adelaide homeowners benefit from spider treatment every 6-12 months, ideally before spring when spider activity increases.

Spider Treatment Cost in Adelaide

See our pest control cost guide for detailed pricing. Typical spider treatment costs:

• Targeted treatment (specific area): $100-$200
• Full interior spider spray: $150-$300
• Full property (interior + exterior): $200-$350

Adelaide-Specific Spider Seasonality

• Spring (September-November): Spider activity increases as weather warms. Good time for preventive treatment.
• Summer (December-February): Peak spider activity. Warm temperatures and abundant insect prey.
• Autumn (March-May): Some spider species mature and become more noticeable.
• Winter (June-August): Reduced spider activity, but indoor spiders may still be present.

Best time for preventive spider treatment: Late winter/early spring (August-September) before activity peaks.

Special Considerations for Adelaide Homes

Garden Beds Against Walls

Garden beds, mulch, and vegetation against your home’s walls create ideal spider habitat. Spiders live in the garden and easily move indoors. Where possible, maintain a gap between garden beds and walls.

Patios and Verandahs

These structures provide shelter for spiders and are common places for webs. Regular cleaning and treatment helps control spiders.

Sheds and Garages

These are common spider habitats, especially redbacks. They offer sheltered, undisturbed environments. Regular inspection and treatment of these areas is important.

When to Call a Professional Spider Controller in Adelaide

Consider professional spider treatment if:

• You have spiders regularly appearing indoors despite DIY efforts
• You’ve spotted redback or white-tail spiders (venomous species)
• Spider webs are recurring quickly after you remove them
• You have a phobia or strong dislike of spiders
• You want peace of mind before a special event
• You’re selling or renting your property

How to Keep Spiders Away Long-Term: Prevention Tips

After treatment, these steps help keep spiders away:

1. Reduce insect prey: Fewer insects = fewer spiders
2. Reduce shelter: Declutter storage areas, remove cardboard
3. Seal entry: Maintain weather-stripping, seal gaps
4. Manage exterior lighting: Reduce lights that attract insects
5. Maintain garden: Keep garden beds away from walls where possible
6. Regular cleaning: Vacuum regularly, remove webs when you see them
7. Consider regular professional treatment: Annual treatment keeps populations controlled

Frequently Asked Questions

What’s the best way to get rid of spiders in my house? For persistent spider problems, professional pest control treatment is the most effective solution. It uses residual insecticides that create a lasting barrier. For occasional spiders, catch-and-release, vacuuming, web removal, and sealing entry points can help.

Are spiders in Adelaide dangerous? Most Adelaide spiders are harmless. The main venomous species are redbacks and white-tail spiders, whose bites are painful but rarely serious with appropriate first aid. Funnel-web spiders (the most dangerous Australian spiders) are NOT found in Adelaide.

How do I get rid of huntsman spiders? Huntsman spiders are harmless to humans. The most humane approach is catch-and-release: trap the spider under a container, slide paper underneath, and release it outside.

Does peppermint oil really repel spiders? There’s limited scientific evidence that peppermint oil repels spiders. Some people report success, others don’t. It’s unlikely to solve an established spider problem but may provide some deterrence.

How much does professional spider control cost in Adelaide? Professional spider treatment in Adelaide typically costs $150-$350 for a full property treatment, depending on property size. Targeted treatments cost $100-$200.

How often should I get spider treatment? Most Adelaide homeowners benefit from spider treatment every 6-12 months. Spring (September-October) is an ideal time for preventive treatment.

What attracts spiders to my home? Spiders are attracted by: prey (other insects), shelter (clutter, webs, undisturbed areas), and entry points (gaps around windows, doors, vents). Reducing insects, decluttering, and sealing entry points all help reduce spiders.

Can I get rid of spiders permanently? Complete permanent elimination of all spiders is unlikely and arguably undesirable—spiders are part of the ecosystem. However, professional treatment combined with prevention measures can keep spider activity at manageable levels and keep them out of living spaces.
