Mold will grow in places with a lot of moisture, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.

What environment does mold grow in?

Water: Molds thrive in damp, humid, and wet conditions. They require water to grow and spread, which is why it is recommended to keep homes – especially walls and carpets – as dry as possible. Water leaks, flooding, high humidity, and condensation all provide moisture mold can use to grow and spread.

What causes mold to grow?

Causes and growing conditions. Mold is found everywhere and can grow on almost any substance when moisture is present. They reproduce by spores, which are carried by air currents. When spores land on a moist surface suitable for life, they begin to grow.
