Can Mold Grow in Desert Environments?

When you typically think about mold growth, heat and moisture might come to mind. The humidity present throughout Palm Springs, CA creates an ideal environment for mold growth in homes and buildings. But can mold grow in desert environments throughout southern California, where moisture may be less of an issue?

The simple answer is yes, mold can grow in desert environments. But it’s a little more complicated than that. To better understand how mold remains present in dry, warm climates, it’s important to understand exactly what mold is and how it grows.

How Does Mold Grow?

According to the United States Environmental Protection Agency (EPA), molds are a type of fungi that occur naturally and play an important role in breaking down dead organic matter like fallen leaves, dead trees, and other debris. Mold growth begins with two simple ingredients: water and oxygen. Wherever both are present, no matter the environment, the opportunity for mold growth presents itself.

And while there are many types of molds, they all require moisture to grow. So while mold may be less present in the desert, the fungal spores that lead to larger mold outbreaks still exist naturally, especially in desert soil.

Dry winds can move these spores, which are just waiting for a source of water or a moisture rich environment to spread further. Or in the case of your home, anywhere moisture gets trapped like wood, drywall, or tiling.

So while mold may be less naturally present in desert environments, modern plumbing and temperature-controlled homes can still create the perfect storm for mold growth.

Does Mold Grow in Heat?

Again, moisture and oxygen are mold’s two main ingredients. And humidity—the combination of heat and moisture—speeds up the mold growth process. So yes, mold not only grows in heat but thrives with the right amount of moisture.

Mold starts growing on damp surfaces within just 24-48 hours, even if the spores themselves may not be visible for weeks after. When visible, mold appears as slightly fuzzy, discolored, or slimy patches that will continue to spread and increase in size, accompanied by a musty odor that causes respiratory symptoms.

Does High Heat Kill Mold?

Extreme heat can kill mold, but it’s usually through the lens of food preparation. According to the United States Department of Agriculture (USDA), most yeasts and molds are heat-sensitive and destroyed by heat treatments at temperatures of 140-160°F. Fortunately, the summer temperatures in California deserts never quite reach those heights.

Mold Growth in Cold Areas

The EPA states that molds can be found almost anywhere and grow on virtually any substance, if some form of moisture is present. Like hot, dry climates, the environments many cold-area homes create can still provide the perfect setting for mold.

Condensation and poor ventilation in basements, crawl spaces, leaky pipes, or cold walls from outside moisture are all areas prone to mold in cold environments.

Mold Growth: Preventative Tips for Homeowners

You can’t always predict when a mold outbreak will strike, but you can put yourself in the best possible position to keep the likelihood of mold growth as low as possible, no matter what type of climate your home is in.

Here are a few steps you can take in your home to mitigate your mold risk:

• Keep your home dry in general; don’t allow water build up anywhere, including shower walls or wet clothes in the washing machine.
• Use mold-killing cleaning products on shower curtains and bathroom tiles regularly.
• Be mindful of indoor plants and the mold that can grow in soil.
• Use exhaust fans in the kitchen and bathroom to limit moisture in the air.
• Act quickly: fix any leaks when you notice them and address water damage before mold can settle in.
• Keep basements and garage areas well-ventilated and consider utilizing dehumidifiers in hot or humid seasons.
• Use waterproof materials in areas that may have regular exposure to water (windowsills, exposed plumbing, bathroom rugs, etc.).
• Consider investing in a moisture detector if you suspect there may be water behind your walls or under your floors.
