While Australia only ranks ninth in terms of contact with venomous spiders, per capita, at .14 deaths per 1,000,000 people, it is still a place with plenty of deadly spiders. In fact, many feel that Australia may have the most deadly spiders on Earth.
Just some of the spiders found in Australia that can harm humans include:
• The Australian Funnel-Web Spider is one of the most dangerous in the world and will often bite rather than run away. It is typically found within 100 km of Sydney and its toxin is highly toxic to primates. Males have more potent venom than females and are often encountered in the summer time. Bites from the males have resulted in death if medical attention is not sought.
• The Redback Spider does not bite often but when it does it is highly toxic and dangerous for the elderly and children. Roughly 20 percent of those bitten by the spider require treatment. There have been no deaths since 1956 when the antivenom was created and most of the bites are from female spiders. Typical symptoms usually involve mild pain that is short-term. Of course, bites can also cause extreme pain and sweating, as well as swelling and swollen lymph nodes. Other issues that can result from the bite include seizure, coma, respiratory failure and more depending on the person who was bitten.
• The Mouse Spider is a burrowing spider that has a deadly venom, which can cause serious harm to humans. Severe symptoms can develop, which require emergency medical treatment but bites are rare and there have been no recorded human deaths.
• The Australian Huntsman Spiders are not very aggressive but they will defend their nests and make threat displays to humans who tread too closely. They can move rapidly and they will often enter houses. IF you are bit, they symptoms are very unpleasant but not life-threatening.
• The White-Tailed Spider is not as dangerous as other spiders, but it is still not pleasant to be bit by one. Its bite usually causes the same type of symptoms as a bee sting, but on occasion nausea, vomiting and headache can develop.
