Mold spreads by creating reproductive cells called spores and sending them into the environment. Mold spores are too small to detect with the naked eye. They are everywhere around us and you cannot avoid being exposed to them.
Mold spores travel in the air and attach to people’s skin, clothing, shoes, shopping bags and belongings. Other ways spores can enter your home invisibly are:
- through open doors and windows
- through your home’s heating, ventilation and air conditioning system
- on the fur of a pet
Once spores enter, they can settle onto carpeting or other surfaces inside your home. You cannot keep spores out of your home, but regular home cleaning and maintenance often can prevent mold problems before they arise.
