Also, don't reach for the head. Reach around towards the back. For snakes, predators come from overhead, i've found that if I reach behind, to get the coils and avoid the head, my grumpy/scaredy snakes don't strike as often.
http://youtu.be/Heqx7dYdBZ4 this vid is, imo, gold, and goes over snake behavior and instinct and handling. I'd recommend giving it a watch and remember, to your snake you're a huge predator who might want to eat her/him. Be patient and think of how you'd feel if the role was reversed. She freaked you out, but you terrified her to the point of striking out to protect her life.
