There are five beasts, all of them are vicious and harmful and there is no sin for one who kills them (and these are): scorpion, crow, kite, rat and voracious dog.
Sahih Muslim Book 15, Hadith 79

Sahih Muslim Book 15, Hadith 78 Next Hadith → A person asked Ibn Umar which beast a Muhrim could kill. Thereupon he said: One of the wives of Allah's Apostle (ﷺ) told me: He (the Holy Prophet) commanded to kill rat, scorpion, kite, voracious dog and crow.
