Top 7 Dangerous Spider Species in Sydney and How to Keep Them Out

Sydney is home to a wild mix of spiders. It has some of the most venomous ones you’ll find anywhere. Most Australian spiders are harmless and don’t pose much of a threat to us humans. Although there are a handful that can pack a punch if you mess with them. If you’re in Sydney, we’ve got you, don’t worry. Here are seven of the ones you should avoid at all costs, and how you can keep them out. 

White-Tailed Spider

White-Tailed Spider

White-tailed spiders often get a bad rap. Even though people often think of them as having necrotic bites, their venom typically just causes a bit of mild pain and some swelling. These poisonous spiders in Sydney are like the night owls of the arachnid world, loving to hang out in dark, quiet spots.

Redback Spider

These notorious little critters are known for their painful bites. Redback spiders love to hang in cosy spots like mailboxes, sheds, and under furniture. But watch out cause their venom can pack a punch, leading to some serious pain, nausea, and sweating. Luckily, antivenom has turned those serious situations manageable.

Mouse Spider

Mouse Spider

Mouse spiders, though less aggressive, have venom similar to the funnel-web spider. You'll often spot them hanging out by rivers and in those cosy suburban neighbourhoods. Male mouse spiders tend to go on little adventures, especially when it’s time to find a mate!

Huntsman Spider

Huntsman Spider

Huntsman spiders are big, fuzzy, and can definitely give you a scare when you see one. But don’t worry, their venom isn’t really a threat to us humans. These spiders help control insect populations in homes. Which actually makes them more of an ally than making them more of than a foe.

Sydney Funnel-Web Spider

Sydney Funnel-Web Spider

Did you know that the Sydney funnel-web spider is one of the most dangerous spiders in Sydney that you can find? This spider is notorious for its highly toxic venom and its feisty attitude when it feels threatened. You’ll often spot it hanging out in gardens and those nice, humid spots. Its venom can lead to some pretty serious reactions, but don’t worry! With prompt medical help and the right antivenom on hand, we can easily prevent any fatalities.

Trapdoor Spider

Trapdoor Spider

Even though trapdoor spiders hardly ever bite, people often mix them up with funnel-web spiders because they look so alike. While their venom isn't really a threat, getting bitten might leave you with some localised pain.

Garden Orb Weaver Spider
