The world’s second most venomous snake, the Eastern Brown snake, was found in a woman’s house in Queensland, Australia on Sunday. The woman had reportedly mistaken it for a harmless carpet snake.

After the woman saw the snake crawl past her bathroom, she contacted the authorities. The Sunshine Coast Snake Catchers responded to the spot after instructing the woman to seal the bathroom door with a towel.

The owner of the snake catching firm, Stuart McKenzie, confirmed that the snake was very dangerous. He added that after the snake catchers reached the house, they went through the bathroom but were unable to find the snake initially.

McKenzie told the local sources that the snake catcher, named Donnie, speculated the snake to have gone into the drain but was found curled up inside a drawer in the washroom. The snake was identified as the eastern brown snake.

The inland taipan, found in central Australia, is considered the most venomous snake in the world.
