Bleach
Houseflies can transmit disease by landing on contaminated surfaces such as garbage or feces, picking up pathogens, and then transferring them to food or other surfaces through their body parts or feces. When people come into contact with these contaminated surfaces, they can unknowingly ingest the pathogens and become sick.
Bleach is the most effective substance for killing mold and removing it from surfaces.
Organisms and pathogens travel quickly on wet surfaces
Substances used for removing pathogens from tools or surfaces are called disinfectants. These chemical agents are designed to kill or inactivate microorganisms, including bacteria, viruses, and fungi, on non-living surfaces. Disinfectants are essential in maintaining hygiene and preventing infection in various settings, such as hospitals, kitchens, and laboratories.
