There are eight species of mouse spider found all across Australia and they’re typically found in burrows, often near rivers or waterways, and can occasionally be found in suburban areas.
Their venom is similar to the funnel-web spiders, although no deaths have been attributed to them; only one case of severe envenomation has been recorded. Studies have shown the funnel-web spider antivenom to be effective for mouse spider envenomation; and because it is sometimes difficult to tell the two species apart, the bites should be treated with the same precaution.
Mouse spiders are rather lethargic and rarely aggressive. The females generally remain in their burrow, while the males wander looking for them, generally in late summer to early winter. Unlike other spiders, mouse spiders are often active during the daytime, while other species from the same family prefer to wonder at night to avoid the heat and the day-active predators.
