Red-Back Spiders
HIGHLY VENOMOUS - DANGEROUS - CAN BE DEADLY
Toxicity of venom - the Red-Back Spider can inflict a painful bite which can be fatal, especially to the young and elderly. An effective anti-venom was developed in 1956. Only a small amount of venom can cause serious illness, as the poison attacks the nervous system. Medical attention should be sought as soon as possible.
White-tail Spiders
VENOMOUS - CAN BE DANGEROUS
White-tail spider bites can cause burning pain followed by swelling and itchiness. In some cases, blistering or local ulceration have been reported – conditions known medically as necrotising arachnidism. Minor bacterial infection of the wound caused by Mycobacterium ulcerans carried by the spider, may be a contributory factor in such cases. A debate continues about the involvement of White-tail spider bite in cases of severe ulcerative skin lesions seen in patients diagnosed as probable spider bite victims. Typically, in such cases no direct evidence of spider bite is available.
