Quick Answer: Does Freezing Mold Kill It?

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.

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?
