A mum says she is terrified that she is now sharing her suburban home with one of the world’s most deadly spiders.

Michaela Egan, 24, took to Facebook to tell the tale of how she found a white ‘cocoon’ on the last banana in the bunch that she had purchased from her local supermarket.

The mother of two, from Rainham, Essex, was soon inundated with messages and suggestions that the webbing belonged to to a Brazilian wandering spider, ranked in the Guinness World Records as the world’s most dangerous, reports Metro.

The spider’s bite can kill in as little as two hours and male victims may suffer a painful erection that can last as long as four hours.

Michaela immediately put the banana in a sealed bag and took it back to supermarket Tesco but she is frightened that the spider has laid eggs and the family are living among them.
