Under a crate of bananas originating from South America, a supermarket worker discovered a spider so deadly that the UK supermarket had to be closed until the creature was hunted down.

25-year-old Kate Whitmore said, “I looked down and noticed this thing. I screamed for my supervisor,” the shop worker told the [Daily Mail of London]. “I’m not usually scared of spiders, but it was huge and creepy and had long hairy legs.”

Animal welfare workers were brought in to hunt down the Brazilian Wandering Spider, a species so deadly, it is credited with killing more humans than any other species of spider. It has even earned a spot in the Guinness Book of World Records for being the most venomous animal in the world.

A worker from the Royal Society for the Prevention of Cruelty to Animals was called in to capture the hairy legged beast. “It was very aggressive and trying to go for me when I was putting it in the box, it was really jumping around and trying to attack me.”
