Linda, There is no way to remove them easily. If I can grab them with a pair of pliers that has a rounded head, I will 'roll' them out by grabbing them and rocking the pliers backwards. For stubborn ones, I use an old screwdriver that I don't care about any more. Once I get the screwdriver underneath, I twist it from side to side rather than prying with it.
If your structural wood won't show, why not just pound the staples all of the way it and leave them?
