Most guys will remove the bark if they have time and seal. If you don't remove the bark you need to spray the bark real good with a bug spray that killsthe borers that hatch when it warms up. I have some in my garage from last winters cutting that I did not remove bark or spray and haven't noticed any bugs eating it but I'm sure if I leave it that way it won't be long.
I actually like to leave the bark and sapwood on for the first year of drying but that's just me.
