How does mold spread?

Mold produces microscopic cells called “spores” that are easily spread through the air. Spores can also be spread by water and insects. Live spores act like seeds, forming new colonies whenever they find the right conditions. Many people researching FAQs about how mold spreads wonder if it’s something they have done that causes mold growth. Living in overly humid environments or keeping your indoor conditions more moist than normal could contribute to mold spreading.
