Interestingly, one of the new study's authors had dealt with a case in which a person who claimed to have been bitten by a white-tailed spider eventually admitted the bite was faked, and the necrosis that occurred was self-inflicted, with a chemical called sodium hydroxide. The study added further evidence to the 135 previously documented, verified cases of white-tailed spider bites in which no necrosis was found, the researchers said. And, after following the patient for more than a month, the researchers found no sign of necrosis.

"He told me he was scared to death, because on the Internet, there are statements still persisting that these cause necrotic arachnidism, and there is a good chance you'll need a skin graft" after a bite, Weinstein said.Ī few days after being bitten by a white-tailed spider, the man developed a rash, which disappeared after a couple of weeks. The 42-year-old male patient whose case is described in the new Toxicon study turned out to be one of those people. The white-tailed spider is a medium-size spider that owes its name to the off-white tip at the end of its abdomen, and is commonly found in homes in urban areas in Australia.Īlthough previous studies have shown no verified evidence of necrosis resulting from the bites of the white-tailed spider, many people are misled by information online not based on credible sources or research that says white-tailed spider bites can, indeed, kill human tissue. Growing evidence from such studies suggests these a few spiders stand wrongly accused of being able to cause necrosis, experts say. In general, the strongest evidence of the effects of spider bites comes from studies in which researchers looked only at cases of "verified spider bites," meaning patients actually caught the spiders that bit them and brought them to the researchers, who examined the bites and the spiders.
