Quick Answer
Nevada has several scorpion species, with the most common being the Desert Hairy Scorpion (largest in the US, 4-5 inches, mild venom) and the Striped Bark Scorpion (2-3 inches, mild venom, most common in homes). The Nevada Bark Scorpion, a close relative of the Arizona Bark Scorpion, is found in southern Nevada (Las Vegas area) and has more potent venom.
