How are mold spores primarily transported indoors?

Mold spores are primarily transported indoors through clothing and pets. When individuals come into contact with mold in the environment, such as outdoor spaces or other contaminated areas, they can unknowingly carry mold spores into their homes on their clothing or through their pets. This passive transfer allows mold spores to enter living spaces and potentially settle, leading to mold growth if conditions are favorable.

Transport via plumbing systems, water leakage, or electrical wiring, while they can contribute to mold growth or moisture issues, is not a direct method for the transport of spores themselves. Instead, plumbing or water issues might create an environment conducive to mold growth after spores have been introduced into the indoor space. Understanding the primary ways in which mold spores can be introduced into homes is crucial for effective mold prevention and remediation strategies.
