Question: is the joro spider venomous?
Answer: "If bitten by the Joro spider, one would likely feel a localized pain and redness with blisters forming," Hoebeke told 11Alive in an email. "Its venom is 'potent,' but not necessarily lethal to humans. Someone who has severe allergies to insect/arthropod bites might react more severely to a bite from the Joro spider.
