Found this googling bad odors and honey:

honey will rot as it ages. Spoiled
honey smells bad and the odor will eventually find
it's way into living areas. And if the bad smell
doesn't prompt a thorough cleanup, the damage
of it as it leaks through wall and ceilings most
certainly will. Aging honey combs will decompose
and as they break down, the rancid honey will
ooze through walls. Dark spots on walls and ceilings
are a sure sign of rotting honey and most nests
hold enough honey to cause this type of damage
following bee removal.
