They will continue to leave dead soldiers at the door all winter. Try not to disturb them. If they get too many, i take a twig and just flick them out of the way. Only open up if some are flying, otherwise try to leave them alone. I will sometimes listen at the hive side and hear the reassuring buzz and just leave them. If you do open, quickly, and sugar syrup is not recomended. search this site for candy board recipe. Only if its needed.
