These spiders are named after their habit of camouflaging the entrance of their burrow to trick their prey into falling inside. They measure about 1.5 to 3cm long and as is often the case, females are distinctively larger than males but males tend to be more aggressive when feeling threatened.
Found throughout Australia’s natural or urban environments, trap door spiders cause only minor symptoms for humans, generally inflicting only localised pain, but sometimes nausea, lethargy and malaise.
Just like the mouse spiders, trap door spiders are often mistaken for funnel-web spiders, especially since the early effects of their bites are similar; these spiders should therefore be treated with caution. While most spiders live for about one year, trap door spiders can live between five and 20 years.
