White mold is an example of the fungus, but it isn’t just one type of mold. White mold describes a wide range of mold species that can appear white in color. Because of the white color quality of such mold species, white mold might be tough to identify. But as is with any mold, it’s essential that you can identify its presence so that you can have the mold growth properly addressed, and removed, to prevent further issues.
What is White Mold?
White mold is not a specific type of mold – many species of mold may appear white. The species of white mold commonly found in homes are aspergillus, Cladosporium, and penicillium. All these molds may also appear gray, green, black or other tints. Moreover, all molds thrive in moist areas where a food source like wood is present.
Generally, it’s not necessary to determine the type of mold you have in your home – all molds have the same negative effects.
Some molds may appear white in their early stages of development. Later, these molds may change color after producing spores. Yet, many molds appear white regardless of age because their spores are not pigmented. The lack of spore pigmentation is caused by the type of material it’s growing on.
Also, white mold appears as powdery and may blend in with the materials it’s growing on, which makes it hard to tell that it’s actually molded.
White Mold vs Mildew and Efflorescence
Sometimes, people confuse white mold with mildew, which may also have a white appearance. However, mildew rarely grows on surfaces other than plants and doesn’t destroy materials. White mold, on the other hand, penetrates the surface of porous materials like wood or drywall and can ruin them.
It’s also common for people to confuse white mold with a substance called efflorescence. It’s a type of salt deposit caused by salty water that seeps through concrete, brick or stone. When the water evaporates, it leaves behind a white crystalline substance that looks similar to white mold.
Unlike white mold though, efflorescence does not pose any health risks and won’t grow or spread.
To tell whether a substance is a white mold or efflorescence, just look at the affected surface. If it’s masonry, it’s efflorescence. Also, put some of it into a drop of water and if it dissolves, it’s not mold. Lastly, squeeze some of the substance between your fingers and if it breaks into a fine powder, it’s efflorescence.
Is White Mold Dangerous?
All types of mold, including white mold can cause health problems. White mold should be removed as soon as possible to avoid health risks and structural damage. Even milder forms of white mold can endanger your health.
Since some people don’t realize that white mold is mold, it may put them at risk for extended periods. The symptoms induced by white mold include allergic reactions, respiratory infections, eye irritations, dizziness, nausea, headaches, and even depression. If you suspect you or a family member has been affected by mold exposure, consult a doctor and have the mold removed immediately. Call us 866.331.9111
