Fight for survival: British man bitten by poisonous spider - species also in Germany. The false widow is small, almost inconspicuous.

But the venom of the spider genus can even be dangerous for humans. Such an infection can turn into sepsis, which can be extremely painful and lead to a serious bacterial infection, a research team from the University of Ireland has found. Until recently, experts believed that those bitten by the false widow were responsible for their own bacterial infection. However, Fritz Wepper also died as a result of a bite from a false widow.
