Woodlouse Spider
Dysdera crocota
The Woodlouse Spider is a striking, medium-sized spider that was introduced to Australia from Europe. It is a specialist predator, almost exclusively feeding on woodlice (also known as slaters or pillbugs). It is easily identified by its glossy reddish-brown head and legs, and pale, sausage-shaped abdomen. Its most notable feature is its enormous, forward-projecting fangs (chelicerae), which are specifically adapted for piercing the tough, armoured exoskeleton of its prey. It is a common resident of suburban gardens, living in moist, dark places where slaters are found. While its appearance and large fangs can be alarming, it is not aggressive and its bite is not dangerous to humans.
For effective control and prevention, professional pest management is recommended.
