As the season arrives of the rainy season 2026 humidity increases, causing many areas inside homes to unknowingly become breeding grounds for mold.

Rainy season 2026: Check these 5 damp spots in your home where mold frequently grows

1. Walls and room corners with poor ventilation

Areas like room corners, behind furniture, or walls regularly hit by rain often have high moisture buildup. If you notice black or green stains or unusual musty odors, it may be an early sign of mold growth.

Prevention methods : Open windows to allow air circulation, regularly move furniture away from walls, and frequently check for leaks in the roof or walls.

2. Bathrooms, especially tile grout lines and shower curtains

Bathrooms maintain high humidity constantly, making them prime mold habitats, particularly in tile grout, corners, and shower curtains that stay wet.

Prevention methods : Use exhaust fans or keep the bathroom door open after use, wipe floors and walls dry, and regularly wash or replace shower curtains.

3. Under the kitchen sink and inside kitchen cabinets

Many overlook the area under the sink where leaks or daily moisture buildup can foster mold growth unnoticed.

Prevention methods : Regularly inspect water pipes and joints; repair leaks promptly and occasionally leave cabinet doors open to air out.

4. Air conditioners and air filters

Uncleaned air conditioners can become reservoirs for mold, dust, and bacteria that disperse into rooms when in use.

Prevention methods : Clean air filters every 1-2 months and service air conditioners according to manufacturer recommendations.

5. Wardrobes and enclosed storage spaces

Clothes, books, or items stored in closed cabinets for long periods, especially during humid weather, may develop musty odors and mold buildup.

Prevention methods : Periodically open wardrobes to air them out, use moisture absorbers, and avoid storing damp clothes or items.

How does "mold" affect health?

Though mold spores are too small to see with the naked eye, they can float in the air and enter the body, causing sneezing, nasal congestion, coughing, eye irritation, skin rashes, or triggering allergies and worsening asthma.

The rainy season is especially favorable for mold growth. Regularly checking the five damp spots in the home—walls and corners, bathrooms, under kitchen sinks, air conditioners, and storage cabinets—helps reduce mold buildup and long-term health risks. If mold stains or musty odors appear, promptly clean and fix moisture sources.
