    Hi Billie Jean – according to Wikipedia, it sounds like the black widow spiders in North American can potentially kill a human with their bite, though this is rare. It sounds like the black widows in Australia, New Zealand and Europe are not quite that dangerous – they can make a human quite sick, but not kill them.
