White-tailed spider ( Lampona cylindrata )
WHITE - TAILED SPIDER BIOLOGY
White-tailed spiders seek cool dark areas under bark and leaf-litter. They often come into houses but are not often seen because the spider is most active at night. Bathrooms are a common area to find this spider due to the cool nature of this area. They are sometimes found in the folds of clothes, towels and shoes.
Bite symptoms are local pain, red mark, local swelling and itchiness, sometimes nausea, vomiting, or headache may occur. The bite from these has been linked with spreading skin ulcers and necrosis. Current treatment involves skin grafts to halt the spread of the necrosis. It is thought that the disease is caused by bacteria present on the spider's fangs rather than the venom itself.

SYDNEY FUNNEL WEB SPIDER BIOLOGY
Males tend to wander during the warmer months of the year looking for receptive females to mate with. They are attracted to water and therefore are found in swimming pools, into which they fall while wandering. The spiders can survive in the pool for up to twenty-four hours and can still bite when removed from the water.
The Common to Sydney, funnel-web spider bite is one of the most dangerous in the world. Bites can be fatal if not treated. An antivenom is available and no fatalities have been reported since its introduction. Seek medical treatment immediately if bitten.
