Male Spiders produce the toxins to help with their own hunting, but they make such a diluted version that they're not harmful to most people. Female black widows, on the other hand, have quickly evolved super concentrated venom that can kill a person. Each year, about 2,200 people report being bitten by a black widow, but most recover within 24 hours with medical treatment. Many people who are bitten develop few symptoms since the spider may not inject its venom. Black widows are not especially aggressive spiders, and they rarely bite humans unless startled or otherwise threatened.[16
Contrary to popular belief, most people who are bitten suffer no serious damage, let alone death. Fatal bites were reported in the early 20th century mostly with Latrodectus tredecimguttatus, the Mediterranean black widow.[
Since the venom is not likely to be life-threatening, antivenom has been used as pain relief and not to save lives.[18] However, a study demonstrated that antivenom and placebo added to standardized pain medication had similar improvement in pain and resolution of symptoms.
