Understanding Redding's Mold-Promoting Climate
Why Redding is Particularly Vulnerable

- Temperature swings: Creates condensation on surfaces
- Seasonal rainfall: October-April brings consistent moisture
- Clay soil: Retains moisture against foundations
- Wildfire aftermath: Smoke particles can feed mold growth
Mold Growth Requirements (All Three Needed)
- Moisture: Our focus for prevention
- Food source: Drywall, wood, dust, fabrics
- Temperature: 40°F-100°F (Redding's typical range)
Prevention Strategy: Control moisture → No mold growth
Comprehensive Prevention Strategies
1. Humidity Control - The #1 Priority
Target Humidity Levels
- Ideal: 30-50% relative humidity

Natural Dehumidification
- Ventilation: Cross-breeze when outdoor humidity lower than indoor
- Houseplants: Some species absorb humidity (Boston fern, peace lily)
- Charcoal bags: Natural moisture absorbers for closets, small spaces
