Common House Spiders You May See Around Your Melbourne Home

Sharing your home with eight-legged intruders is rarely a welcome experience. While most spiders are more of a nuisance than a threat, Australia is home to some famously venomous species. For Melbourne residents, knowing how to identify common house spiders is the first step in understanding whether you’re dealing with a harmless guest or a dangerous pest.

Here’s a guide to the common spiders you might find in and around your home, and what you should do about them.

Harmless (But Unwelcome) Spiders

These spiders are generally considered low-risk to humans but can become a nuisance when their populations grow.

1. Daddy Long-Legs Spider (Pholcidae)

• Identification: Instantly recognisable by their tiny, pea-sized body and extremely long, delicate legs. They are often found in quiet, undisturbed corners of the house, in sheds, and under furniture.
• Risk: They possess venom to subdue their insect prey, but their fangs are too small and weak to penetrate human skin. They are not considered dangerous.

2. Huntsman Spider (Sparassidae)

• Identification: Large, fast-moving, and often alarming in appearance. Huntsman spiders are typically grey or brown with long, hairy legs that splay outwards. They are famous for entering homes and cars.
• Risk: Despite their intimidating size, huntsman spiders are not aggressive and their venom is not dangerous to humans, though a bite may be painful. They are excellent pest controllers, preying on cockroaches and other insects.

3. Black House Spider (Badumna insignis)

• Identification: A dark, robust spider that builds messy, lace-like webs in the corners of windows, on verandas, and in sheds. They are timid and will usually retreat when disturbed.
• Risk: They are not aggressive, but a bite can be painful and cause localised swelling. Professional treatment is often required to manage their populations due to their reclusive nature.

Venomous Spiders to Watch Out For

These spiders are less common inside homes but require extreme caution. A bite from these species needs immediate medical attention.

4. Redback Spider (Latrodectus hasselti)

• Identification: The female is a glossy black spider with the iconic red or orange hourglass-shaped stripe on her abdomen. They build messy, tangled webs in dry, sheltered places like mailboxes, under outdoor furniture, in sheds, and around pot plants.
• Risk: Highly venomous. A bite can be excruciatingly painful and cause severe symptoms. If bitten, seek immediate medical attention.

5. White-Tailed Spider (Lampona cylindrata)

• Identification: A slender, dark grey or black spider with a distinct white or grey tip at the end of its abdomen. They are nomadic hunters and are often found indoors after being brought in on firewood or clothing.
• Risk: A bite can cause initial localised pain, redness, and swelling. While past reports linked their bites to necrotic ulcers, recent studies have largely debunked this myth. However, bites can still be painful and may become infected.

 

What to Do About a Spider Problem

While a single spider can often be managed with a glass and a piece of paper, a recurring presence or an infestation requires a more robust solution. Spiders are a sign of a healthy insect population, which is their primary food source.

Frequently Asked Questions About Spiders

1. Is it true that you’re never more than a few feet away from a spider? While this is a popular saying, it’s an exaggeration for the inside of a clean home. However, in a garden or shed, it’s much more likely. Spiders are incredibly common in our environment, but they generally prefer to stay hidden and away from humans.
2. Do “daddy long-legs” spiders have the most potent venom? This is a popular urban myth. While they do have venom to kill other spiders (including Redbacks), there is no scientific evidence to suggest their venom is particularly dangerous to humans. Furthermore, their small fangs cannot effectively bite a person.
3. How can I prevent spiders from entering my house? You can reduce the likelihood of spiders entering by sealing cracks and gaps around doors and windows, installing fly screens, keeping your garden tidy, and turning off exterior lights at night, which attract the insects that spiders prey on. However, for a persistent problem, a professional barrier treatment is the most effective solution.
