Regards, dude! Two mating types are created during sexual reproduction, and because both mating types originate from the same mycelium, homothallic fungi can self-fertilize. Plan a yearly mold inspection at the very least. When mold develops in a small space, remove it. Do not wait for it to spread throughout the house. To lower the chance of mold growth, keep your house tidy and clear of debris. Fix any leaks right away in your house. Ventilate any wet spaces in your house, especially the laundry room and bathroom.
