If disturbed it will hiss loudly and strike quickly. Hikers are at risk, especially when placing hands onto rocks where one of these snakes may be sheltering. The venom of this snake is both neurotoxic and cytotoxic and in addition to pain and swelling may also cause respiratory distress. There is no antivenom for the venom of this snake and victims are treated symptomatically.
