The symptoms of allergies, including watery eyes, runny noses, sneezing, itching, coughing, wheezing, difficulty breathing, headaches, and fatigue, can be brought on by exposure to a lot of mold spores. A person's sensitivity may increase with repeated exposure to mold, leading to more severe allergic reactions.

Mold will develop in areas with a lot of moisture, such as near pipes, windows, and roof leaks, as well as in areas that have recently flooded. On cardboard, ceiling tiles, paper, and wood products, mold thrives. Dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery are other materials where mold can grow.
