Redback spiders belong to the Family Theridiidae, which is found worldwide. A Redback’s bite occurs frequently, particularly over the summer months. Only the Female bite is dangerous to humans, causing serious illness or death. However, since Redback Spiders rarely leave their webs, humans are not likely to be bitten unless a body part such as a hand is put directly into the web. The venom acts directly on the nerves, resulting in release and subsequent depletion of neurotransmitters.
Keep an eye out where you’re walking, especially during the warmer seasons.
Fun Fact, the notorious Black Widow Spider, found in the United States, is a close relative of the Redback Spider, and only differs in appearance by the absence of a red dorsal stripe, as shown above.
