Q. Can mold make people sick?
A. Excessive mold spores indoors can trigger allergic reactions, breathing disorders, and asthma attacks. Mold spores can become elevated indoors when mold grows on surfaces or when insufficient ventilation or filtration is available to remove mold that comes in from outdoors. Mold can cause adverse health effects, whether the mold is alive or dead. This is the reason why mold growth should be cleaned up by professionals. If microscopic mold spores are spread throughout the indoors, people can react long after mold is improperly removed.
