Where ever you travel in the world people ask about Australia’s deadliest spiders hiding in our homes. But for Australians it is about awareness and educating our children on spiders and what to do if bitten.
A lot of spiders found around the home are actually not that dangerous but the stress from seeing one drop from the fan in the bathroom when your showering or on the window of your car can be enough to scare most people. It is true what they say that nothing turns you into a karate master quicker then walking into a spider web crossing your path.
But what are the deadly spiders could you find hiding around your home?

Although the Australian Tarantula isn’t as deadly as some of the other Australian spiders it still can make you very ill with fever and vomiting that can last for 6 hours! However, these are considered deadly to our pets with bites causing death in some cats and dogs.
5. White Tail Spider

White tail spiders are found wondering throughout Australia. They enjoy living in linen such as clothes, towels and sheets. Which is a scary thought when tucking your children into bed for the night.
They are not web spinning spiders but will by night hunt out other spiders such as the black house spider for a late night snack.
Their bite has been a common subject of discussion as it is said that a bite from a White Tail Spider can cause arachnogenic necrosis, that is open sores caused by the death of the bites surrounding tissue. However, it is now believed that the bite itself causes localised pain and swelling with some mild general effects.
4. Trap Door Spider
Appearance: Females are bigger then the males both are covered with fine brown to dark brown hair.
