You may find that no matter where you live or what temperature it is, mould may grow anywhere in your home. Whether it is humid or dry, these organisms are resilient and adaptable and can thrive across different climates.

At ICE Cleaning, our thorough mould remediation services can effectively remove mould from any surface in your home, providing a clean environment and better indoor air quality.

Read on to learn more about preventing growth hotspots and tackling climate-induced changes.

Understanding mould and its resilience

Mould is a type of fungus that is ever-present in our environment and shows remarkable resilience. This is because it adapts well to various conditions, thriving even in places where it may seem uncommon.

It can grow on any organic material, provided there is moisture present. Mould also has unique survival mechanisms, allowing it to persist under challenging climates.

The resilient nature of mould stems from its reproductive spores, which can survive harsh conditions. These microscopic particles float around, waiting for favourable conditions to start creating new colonies.

Mould in humid climates

Humid climates are ideal for mould growth. The constant warmth and high humidity let mould spores thrive, leading to rapid colonisation of surfaces.

This is because mould needs moisture to grow. In humid regions, like Western Europe, it is more common. Moisture from rainfall, fog, and dew provides an endless supply.

The problem gets worse indoors, where ventilation can be poor during winter. High indoor humidity combined with organic materials such as wood or fabrics gives mould everything it needs to multiply quickly.

Mould in dry climates

Despite popular belief, mould can survive and even thrive in dry climates. A genus of mould, Aspergillus, is the most common type to be discovered in dry conditions; it has over two hundred species.

Moulds have developed unique strategies, such as producing spores that remain dormant until they get access to water to cope with the lack of moisture. Dormant or dead mould can still pose a threat and continue to spread, so you must be vigilant despite this.

Places where mould can grow

Mould can grow in areas like kitchens and bathrooms, which are mould hotspots because of their high moisture levels. It can also grow on your houseplants, as overwatering creates the perfect damp environment for mould.

In colder climates, poorly insulated walls become cold spots where condensation forms, attracting mould growth. In warm weather conditions like those in the UK summer, humid air can lead to the accumulation of mould on windowsills.

Wooden structures or garden sheds are also vulnerable to spores and mould. Vehicles, including motorhomes, are often forgotten as we use them daily and think closed windows can prevent mould when it can actually encourage it.

Preventive measures against mould growth

Mould prevention starts with moisture control. You must keep indoor humidity levels below 60%. A dehumidifier can maintain humidity levels below this level, and you can measure this with a hygrometer.

Good ventilation also helps, like exhaust fans in kitchens and bathrooms and standing fans, to help reduce moisture build-up. Try to clean damp areas regularly and remain vigilant for leaks: fix them promptly to avoid mould growth.

The science behind mould's persistence

Mould is built for survival as its spores can stay dormant until conditions are right for growth. Spores have a tough outer shell that protects the inner genetic material from harsh environments. This lets them survive in both hot climates and freezing winters.

When they find favourable conditions - moisture, warmth, organic matter – they start growing again. This ability of mould spores to go into dormancy when environmental conditions are not ideal is one of its survival strategies. The process helps ensure their longevity across various climates.

Impact of climate change on mould growth

Climate change is shifting the world's weather patterns, affecting mould growth. Warmer temperatures and increased humidity are favourable for mould spores to thrive. Rising global temperatures lead to more humid conditions, creating an ideal environment for mould. 

Moreover, with a changing climate comes unpredictable weather events like floods. These leave behind excess moisture, therefore contributing to mould accumulation. As we grapple with climate change, we may also need to deal with increasing instances of mould growth.

Frequently asked questions

What is the best climate to avoid mould?

The driest climates with low humidity are generally the best for avoiding mould, as it thrives in moist conditions.

What climate does mould grow best in?

Mould grows optimally in warm, humid environments. It particularly likes tropical and subtropical regions where moisture levels are high.

What climate is needed for mould?

A damp environment is key; any region that's regularly exposed to moisture can host mould growth. Cold or hot doesn't matter much if there's enough wetness around.

Is mould a problem in dry climates?

Mould is not typically common in dry areas due to lack of moisture, but if there are leaks or poor ventilation, it can still pose an issue.
