Bites appear to cause surprisingly mild pain, given the spider's size, and no systemic problems. Mouse spiders Ground dwelling spiders with large fangs, and venom which is reported to be more toxic than that of the funnel web spider - in mice. Apart from a single case from Queensland, all reported bites by these spiders have been minor. The Queensland case had some similarity to envenoming by a funnel web spider. Centipedes These have fangs and venom glands at the head end and bites may cause severe local pain.
Infection sometimes occurs.
Scorpions None of the many species of Australian scorpions is dangerous to humans but most cause intense local pain when they sting. This usually lasts only a short while, and systemic symptoms rarely occur and are never severe. The most important ticks are those which cause paralysis, discussed under the section on tick antivenom . Many other ticks may bite humans causing a variety of local reactions, usually local irritation or pruritis. A few may sometimes cause a mild systemic illness, including malaise, nausea or headaches.
