Trapdoor Spiders Trapdoor spiders are found across most of Australia and consist of many different species from several families. Trapdoor spiders are robust spiders and black or brown in colour. Some species have paler markings or a silky covering of hair. They range in size from one to five centimetres depending on the species. Different species of trapdoor spider are found in all parts of Australia including Tasmania. They are more diverse in moist forest habitats. Trapdoor spiders live in silk-lined burrows which they dig in the soil. The burrow protects the spider from predators, parasites and provides semi-constant conditions of temperature and humidity. Some trapdoor spiders reach a large size and can deliver a painful bite with large fangs. However, symptoms are usually no more than local pain and swelling. Seek medical attention if symptoms persist and use caution to collect the spider for a positive identification.
