White tail spiders are common in Australia and New Zealand and are often feared because of stories about painful bites and skin damage. These fast-moving spiders are recognized by the pale tip on the end of their dark abdomen. Although many people believe white tail spider bites are highly dangerous, research shows that most bites cause only mild to moderate symptoms. Learning how to identify white tail spiders, understand bite symptoms, and use proper treatment can help reduce fear and improve safety around homes and gardens.
