I planted Hyacinth Bean Vines and they are just sprouting. Has anyone had trouble with deer eating them?

We are putting up an electric fence around our garden because the deer eat everything, but the H. Bean Vines are not in the garden. I hate to have to keep them sprayed, but if the deer are a potential problem, I will have to spray them with something to keep the deer from devouring them...and the rabbits.
