It was narrated from Abu Saeed that the Prophet ﷺ said: "The one in Ihram may kill the snake, the scorpion, the aggressive predator, the vicious dog and the harmful mouse." It was said to him: "Why is it said that they are harmful?" He said: "Because the Messenger of Allah ﷺ woke up because of one, and it had taken the wick (of the lamp) to burn down the house."
