Each time the spider grows bigger, it has to widen its burrow and in the door-building species, add another rim to the door. They will then make their own miniature burrows. When the spiderlings have hatched, they remain for several months before dispersing on the ground. The female Trapdoor spider will lay her eggs several months after mating and protects them within her burrow. The male usually escapes being eaten in order to mate with several females, before dying. Mating takes place within the females burrow. Mature male Trapdoor Spiders wander during humid weather in search of a mate. Trapdoor spiders eat all types of insects even frogs, baby birds, baby snakes, mice and small fish. Sigillate Trapdoor spider burrows are made with soil or litter trapdoors. They can be distinguished from Funnel-web spider burrows by the absence of silk trip lines around the entrance. Often they are found scattered over lawns.

The spider detects the prey by vibrations and when it comes close enough, the spider jumps out of its burrow and captures it. Prey is captured when insects or other arthropods venture too close to the half-open trapdoor at night. The spiders, who are usually nocturnal, typically wait for prey while holding onto the underside of the door with the claws on their tarsi (the cluster of bones in the foot between the tibia and fibula and the metatarsus). The trapdoor is hinged on one side with silk. The trapdoor that these spiders construct is difficult to see when it is closed because of the plant and soil materials that effectively camouflage it. Sometimes they like to make their burrows beside creeks or rivers so they can catch little fish. A Trapdoor spiders burrow is around 30 centimetres deep and 5 centimetres across.
