Mold spores are very easily transported to different areas by attaching themselves to various hosts. These hosts would include people, animals, shoes and they even enter through open windows and doors. The spores then thrive and grow where it is damp and moist. Areas and substances where black mold can be found include water soaked wood, ceiling tiles, wall paneling, cardboard, even items made of cotton. Black mold can grow on drywall and insulation and can infest areas in the floors, walls and ceilings.
Moisture is essential to the growth of black mold, and when it is wet it is shiny in appearance.
If you were to physically touch a spot of black mold, it would feel slimy and would smear on the area. When you are contemplating clean up of black mold, you need to verify the extent of the problem. Many of the infested areas will be relatively small and be a result of small leaks or plumbing problems. After discovering the root of the problem and rectifying it, you can disinfect the area with bleach. A mixture of one cup bleach to a gallon of water is sufficient to disinfect the area.
