Habitats
Redback (Latrodectus hasselti)
Redback spiders are very adaptable to their environments although they do prefer dry habitats such as deserts and sclerophyll forests, they will still find their way into urban areas where they can still thrive.
Wolf spider (Tasmanicosa godeffroyi)
Wolf spiders are adaptable to their surroundings as well, although they do prefer a wet/damp environment but they can still be found anywhere from in shrublands to urban gardens.
Funnel-web (Atracidae)
The Australian Funnel Web prefers moist and cool areas where they will burrow under things such as logs and rocks, and they are frequently found in urban settings.
Trapdoor (Arbanitis rapax)
Trap door spiders are most often found in dry terrain where they will burrow thin tunnels that reach up to 25cm of length that they inhabit.
Daddy-long-legs (Pholcus phalangioides)
The Daddy-Long-Legs spider prefers a warm and somewhat humid environment and is not suited for cold weather. This is why they are commonly found in human homes.
Behaviour
Redback (Latrodectus hasselti)
The Redback spider is a mostly nocturnal and highly venomous spider that spins a triangular shaped web. Once the redback starts its web it will most likely stay there for the rest of its life. Its web is so strong that it can hold small reptiles although they will mainly only eat small insects.
Wolf spider (Tasmanicosa godeffroyi)
Wolf spiders have a very interesting hunting method, as they will burrow a hole into the ground and put one small line of webbing across the burrow. It will then wait at the entrance of the burrow utilising its colour and hair as a method of camouflage and then wait for prey such as small insects which it will then attack as it is trapped in the webbing. Also, a bite from a wolf spider would not be life threatening but should still be treated like it is.
Funnel-web (Atracidae)
The Funnel-web is venomous, and a bite from one could potentially be life threatening. They also burrow underground but mostly under things like rocks and logs however in some cases they have been found in trees.
Trapdoor (Arbanitis rapax)
Trapdoor spiders also make burrows. In most cases they are not territorial and will back away in the face of danger, though in some cases they will stand up and show their fangs. They will rarely go far from their burrows but they will in some rare occasions wander during the night.
Daddy-long-legs (Pholcus phalangioides)
The Daddy-long-legs is capable of killing many of the most dangerous spiders to humans like Redback spiders, despite this they are still next to harmless to humans as their fangs are not long enough to inject their venom effectively. The Daddy-long-legs has many predators and some of which will simply jump on their web and attack the long-legs.
Addressing a Bite
If you are bitten by any spider, treat it as if it is a highly venomous bite even if you don't think it is and get it assessed by a doctor or health care professional.
No spider will go out of its way to bite or harm a human and they can actually be quite helpful to have around the house to kill insects.
However if you have a large spider problem, practise spider control or engage a pest controller. To avoid a spider bite, never attempt to approach, capture, or kill a spider.
