No, mold spores won't continue to grow in truly dry places, but they can remain dormant and viable until moisture is introduced.
Here's a more detailed explanation:
Mold requires moisture to thrive. Without sufficient water, active growth stops. However, the spores themselves are incredibly resilient. They enter a dormant state, almost like a seed waiting for the right conditions to sprout.
Here's a breakdown:
- Dormancy: Mold spores can survive in dry environments for extended periods, even centuries. They simply stop growing and "wait" for moisture.
- Activation: When moisture becomes available (through humidity, leaks, spills, etc.), the spores reactivate and begin to grow again.
- Suitable Surfaces: Even in otherwise "dry" places, localized moisture can provide enough sustenance for mold to grow, especially on surfaces like drywall, wood, and fabric.
- Examples of "Dry" Places with Potential for Mold:
- Attics: While generally dry, roof leaks or condensation can introduce moisture.
- Basements: Even with dehumidifiers, basements are often more humid than other areas of a home.
- Closets: Poor ventilation can trap moisture.
- Storage Units: Fluctuations in temperature and humidity can lead to condensation.
Therefore, while mold requires moisture for active growth, "dry" places are not immune to mold problems, especially if there's any intermittent or localized source of dampness. Addressing moisture sources is key to preventing mold growth.
