Question

Why is household mold/mildew smell worse at night than during the day?

Answer 1

Its prob the humidity.

Answer 2

Because it is more humid at night. Get rid of the mold and mildew by putting bleach in a spray bottle and diluting it, then spraying the mold and mildew. it will stop the smell, and the stain will go away. I don't recommend this on wood or porous places. I would do this for maybe tiles, or a bathroom.

Answer 3

They are fungi and multiply fast during the cold humid night. Wash it up then use Lysol after rinsing then sundry it,
