Why Mould Loves the Monsoon
Mould is a type of fungus, and like all fungi, it thrives in damp, warm, and poorly ventilated environments. The Indian monsoon provides the perfect conditions. As humidity levels soar, often exceeding 80-90%, moisture settles on walls, furniture, and fabrics.
This creates a breeding ground for mould spores, which are always present in the air, to land, multiply, and form visible colonies. Areas like bathrooms, kitchens, closets, and spaces behind large furniture are particularly vulnerable as they trap moisture and have limited airflow.
A Silent Health Hazard
Exposure to mould can be more than just a nuisance; it's a health concern. Inhaling mould spores can trigger allergic reactions, especially in sensitive individuals. Common symptoms include a stuffy nose, coughing, wheezing, itchy eyes, and skin irritation. For people with asthma, mould exposure can worsen their condition and lead to more frequent attacks. While most household moulds are not toxic, long-term exposure to any mould is best avoided to maintain a healthy living environment.
Know the Warning Signs
The most obvious sign of mould is seeing it—black, green, or white patches that look fuzzy or slimy. However, mould often grows in hidden places. A persistent musty or earthy smell is a major red flag, often indicating mould growth behind walls, under flooring, or inside cupboards, even if you can't see it. Other subtle signs include bubbling or peeling paint on walls, unexplained discoloration, or experiencing a flare-up in allergy symptoms only when you are at home.
Prevention: Your First Line of Defence
Keeping your home dry and well-ventilated is the key to preventing mould. Whenever the rain stops, open windows and doors to allow for cross-ventilation, which helps reduce indoor humidity. In kitchens and bathrooms, always use an exhaust fan during and after cooking or showering. It’s also wise to keep furniture a few inches away from walls to improve airflow. Promptly fix any water leaks from pipes or roofs. For closets and storage areas, consider using moisture absorbers like silica gel packets or even bowls of coarse salt to draw dampness out of the air.
How to Safely Remove Small Mould Patches
If you find a small patch of mould (less than 10 square feet), you can often handle it yourself. A simple and effective cleaning solution is white vinegar. Its natural acidic properties kill most species of mould spores. Pour undiluted white vinegar into a spray bottle, spray the affected area, and let it sit for an hour before scrubbing with a brush and wiping clean. A solution of baking soda and water can also be used. Always wear gloves and a mask to protect yourself from inhaling spores during cleanup.
When to Call a Professional
While DIY methods work for minor issues, some situations require professional help. If the mould-affected area is larger than 10 square feet, or if it returns despite your cleaning efforts, it's time to call a specialist. Professionals should also be called if you suspect mould in your HVAC system, as this can spread spores throughout the entire house. If mould growth is the result of major water damage or sewage backup, a professional remediation service is essential to ensure the problem is dealt with safely and thoroughly.
