Carpet can smell moldy before you see any growth because mold spores are microscopic and can thrive deep within the padding or backing, where moisture gets trapped. The odor comes from microbial volatile organic compounds (MVOCs) released as mold begins to colonize. By the time you spot visible fuzz, the problem has likely been developing for days or weeks, often hidden under furniture or along baseboards where air doesn't circulate well.
