Are White Tail Spiders Dangerous?
White tail spiders are one of the most talked-about spiders in Western Australia. Many homeowners become concerned the moment they spot one inside the house, largely because of long-standing myths about dangerous bites and severe skin reactions. But how dangerous are white tail spiders really?
At Pest Control Mandurah & Surrounds, we regularly help homeowners across Mandurah and the Peel Region deal with spider activity safely and professionally. Here’s what WA residents should know about white tail spiders, where they hide, and when it’s time to seek professional pest control.

What Is a White Tail Spider?
White tail spiders are medium-sized hunting spiders commonly found throughout Australia, including across Mandurah, Falcon, Dawesville, Halls Head and surrounding suburbs.
They are usually identified by:
A slim dark grey or black body
Long legs
A distinctive white tip on the end of the abdomen
Fast movement when disturbed
Unlike web-building spiders, white tails actively hunt other spiders for food, which means they often move around homes searching for prey.
Are White Tail Spider Bites Dangerous?
One of the biggest myths surrounding white tail spiders is that their bites cause flesh-eating skin ulcers. While this belief became widespread years ago, medical research has largely disproven the connection.
Most white tail spider bites result in:
Mild pain or irritation
Redness and swelling
Itching
Temporary discomfort
Serious reactions are uncommon and may instead be caused by secondary infection, allergic reactions or other underlying medical conditions.
That said, any spider bite should still be monitored carefully, particularly if symptoms worsen or signs of infection appear.
Where Are White Tail Spiders Commonly Found?
White tail spiders prefer dark, sheltered areas and are frequently found indoors, especially during warmer months.
Common hiding places include:
Inside shoes left on the floor
Clothing piles
Towels and bedding
Behind furniture
Garages and sheds
Wall crevices
Laundry rooms
Because they hunt other spiders, homes with existing spider problems may attract more white tail activity.
Why Are White Tail Spiders Common Around Mandurah?
Mandurah’s coastal climate creates ideal conditions for many spider species. Warmer temperatures, humidity and insect activity can all contribute to increased spider populations around homes and businesses.
White tail spiders are particularly common in:
Older homes
Coastal properties
Homes with gardens or dense vegetation
Areas with existing insect or spider activity
Storage-heavy garages and sheds
Suburbs throughout the Peel Region often experience increased spider activity during warmer weather and seasonal changes.
How to Reduce White Tail Spider Activity Around Your Home
There are several ways homeowners can help minimise spider activity indoors:
Reduce Clutter
Spiders love dark, undisturbed spaces. Keeping storage areas tidy reduces hiding spots.
Shake Out Shoes and Clothing
Especially if items have been left on the floor or outside.
Seal Gaps and Cracks
Prevent spiders from entering through doors, windows and wall gaps.
Remove Other Spider Activity
White tails hunt other spiders, so reducing overall spider populations can help.
Keep Outdoor Areas Maintained
Trim vegetation away from the home and reduce outdoor insect attraction.
When Should You Call Professional Pest Control?
If you’re regularly spotting white tail spiders inside your home, professional treatment may be the safest and most effective solution.
Professional spider control can:
Treat active infestations
Target hidden spider activity
Reduce food sources
Create protective barriers around the property
Help prevent recurring problems
At Pest Control Mandurah & Surrounds, we provide safe and effective spider treatments tailored to homes across Mandurah and surrounding suburbs.
Final Thoughts
White tail spiders may look intimidating, but the reality is often less alarming than the myths suggest. While bites can cause irritation and discomfort, serious complications are uncommon. However, no homeowner wants spiders regularly appearing indoors.
Maintaining a clean home, reducing hiding spots and organising professional pest treatments when needed can help keep your property safer and more comfortable year-round across Mandurah and the Peel Region.
