Freezing temperatures can cause mold spores to hibernate, but it doesn’t kill them.
Immediately when temperatures rise after a winter spell, the spores will reactivate and grow into mold.
Molds even grow faster when the temperatures levels rise beyond room temperatures.
Can you kill mold in the freezer?
Extreme cold, freezing, and heat can deactivate spores but it does not kill them. They are resistant to desiccation (drying out). To sum it up, there are four critical requirements for mold growth – the presence of mold spores, available mold food, appropriate temperatures and considerable moisture.
What temperature will kill mold?
Heat and Mold

Can mold be killed with heat?
There are several methods of removing mold, many of which necessitate the use of harsh chemicals. Extreme heat or extreme cold can kill most mold spores. High or low temperatures can kill mold spores.
