"Even if these photographs are genuine, they create an exaggerated sense of the danger posed by brown recluse spiders. As Phillip Anderson, a Missouri physician who specializes in brown recluse spider bites, explained in an article for the medical journal Missouri Medicine, "Almost all brown recluse spider bites heal nicely in two to three months without medical treatment at all. Also the long-term medical outcome is excellent without treatment." Furthermore, says Anderson, "We are not aware of any verifiable deaths caused by the bite of the North American brown recluse spider." (He noted that several deaths from such wounds "had been reported in medical journals, but none of the reports is convincing.") He also reported that out of "about 1,000 credible recluse spider bites," he was only aware of "about a dozen cases of impressive, sustained hemolysis."
