Some mouse spiders have a very toxic venom which is potentially as dangerous as that of the Sydney Funnel-web Spider. However, few cases of serious envenomation have been reported, the most serious resulting from the bite of a male Eastern Mouse Spider, Missulena bradleyi near Brisbane. Although the males are often sighted, bites by Red-headed Mouse Spiders are rare, probably because the spiders occur in less densely populated areas. Because of their potential toxicity to humans, first aid treatment should be provided as recommended for funnel-web spider envenomation. Fortunately, funnel-web spider antivenom has proven effective in cases of mouse spider bite.
