Does mold odor go away when mold is killed? Or does it persist?

[Guest guest]

--or do you have to clean up all the dead mold before the odor goes

away?

I wrote yesterday about this--feel I'm being ripped off by a doctor's

office who sold me a device/oil to kill mold. Musty smell remains

after treating the area intensively.

Need scientific fact re: mold odor persisting or not when mold is

killed off. This was inside a kitchen cabinet, and also a musty

chair. I have not done other cleaning yet.

Thanks.
