Get to Know the Most Dangerous Spiders in Australian Homes and their Danger Ratings!

It’s common for us to encounter spiders in our homes. It is already a part of our everyday life in Australia. Spiders are everywhere and they do come in many varieties. There are tiny spiders like Whitetail, big ones like Huntsman to even dangerous and deadly spiders such as Funnel-web. 

To get a little background and be aware of their existence, we’ve put a list of the most dangerous spiders in the Australian backyard and what danger they bring in our homes. 

Australia's Most Dangerous Spiders

Daddy Long Legs

There is an urban legend that says daddy long legs spiders, one of the most dangerous spiders, are the most venomous spider in the world if their fangs could sink into our skin. This is actually 100% false. Daddy long legs rarely bite, and their venom is not strong enough to affect humans. The urban legend has never been proven. They can cause no more danger than a common house fly. 

They like to build their webs in sheltered areas like houses, sheds, and garages. They hunt other insects and spiders so they can likely keep your house pest-free. They can even hunt redback spiders! 

Funnel Web Spider

Funnel web spiders have a fearsome reputation as they are the most dangerous spider in Australia. And they are very common in our backyard! They have huge fangs and their venom is enough to kill an adult human. 

There have been no recorded fatalities since 1981, however, you should still watch out for these nasty critters!

TIP: Do not walk barefoot on grass in the late afternoon as this is the time the funnel web spider looks for a mate. After mating the female funnel web spider will eat their mate!

Huntsman Spider

These giant spiders are known for their scary and hairy look. However, despite their appearance, huntsman spiders are not considered to be one of the dangerous spiders. They will just give you a little scare than cause any damage or harm. Know that they can still give you a painful bite, but it’s still very uncommon as they would rather run away than attack you. 

Unsuspecting drivers have been known to be involved in car accidents due to these dangerous spiders. So the greatest danger from them is more in being caught off guard and being injured because of fright. 

They might be scary but they are also beneficial around our house as they often hunt and eat smaller bugs.

Garden Orb Weaver

Garden Orb Weaver spiders are found throughout Australia as they are the most common and dangerous spiders on our list. They are very active at night and would weave their long, vertical webs between branches of trees, waiting for their prey. 

These spiders are reluctant to bite and their venom is mostly harmless. However, once threatened, they can be aggressive and their bites can give a nasty sting and swelling. In this list, they have the most reported cases every year because aside from their bites, their huge webs can cause huge surprises and can lead to panic and injuries.

White-tail Spider

Many have developed a fear for white tail spiders over the past 40 years. Some believed that these dangerous spiders are extremely threatening to the point that they have flesh-eating venom. It’s a fact that their bites can cause initial burning pain followed by swelling and itchiness, however, it is an urban legend that they have flesh-eating venom. 

White tails are mostly active at night and based on a 2003 survey, 85% of bite incidents happened after 4 in the afternoon. Be sure to check and shake your clothes and towels as they like to hide in folded fabrics! 

If you do get bitten by a white tail, quickly apply an ice pack and get immediate assistance by contacting the Poisons Info Hotline (13 11 26).

Redback Spider

Redback spiders, one of the most dangerous spiders, are very common in Australia. They are often found in considerable numbers around houses and properties. Their favourite hiding places are garden sheds and mailboxes, and sometimes even under your toilet seat! 

Only one redback spider fatality has been reported in the last 70 years, but there are around 2000 redback bites every year! Their bites can cause headaches and nausea and are very painful. However, in most cases, redback’s fangs are too small to sink into your skin. Be sure to keep away from them even if their look can be unassuming. 

In most cases, spiders are not a serious threat to us in our daily lives. However, once unchecked, the most dangerous spiders in Australian homes can still lead to serious issues. Prevention is always the key.
