Mold typically emits a musty, stale odor that is often likened to the smell of wet socks or rotting wood. This distinctive scent is a byproduct of mold metabolism, releasing various microbial volatile organic compounds (mVOCs) into the air as it grows. These mVOCs can vary, producing a range of smells from damp and earthy to pungent and sour. The intensity and character of the mold smell can depend on the type of mold, the level of infestation, and where it's growing. For instance, black mold is notorious for a stronger, more noxious smell, akin to the earthiness of decaying leaves. If you notice a persistent odor that lingers despite cleaning, especially in areas that have been exposed to moisture, it may be an indication of mold presence.
