Mold is a type of fungus that thrives in damp, humid environments. It can grow on a variety of surfaces, including walls, floors, and ceilings, and is commonly found in areas with water damage, such as basements, bathrooms, and kitchens. While mold can appear harmless, it can pose significant risks to your health. Exposure to mold spores may cause respiratory problems, allergies, and other health complications, particularly for individuals with pre-existing conditions like asthma or weakened immune systems.
