Millions of tiny critters fight over food and a comfortable place to settle and multiply. Fortunately you can't see them, because most are too small to be seen. Biological contaminants are either living organisms, such as bacteria, viruses, fungi and dust mites; or are organic dead substances, such as animal dander and dried insect droppings.
Like you and I, these little polluters like to live in comfort. While we, however, may not like warm and humid conditions, most of them do. But some don't care about the temperature and also thrive in cool and damp places. The nastier ones, like viruses and bacteria, prefer a living host as their home.
Another condition for the living organisms to survive is the availability of food - nutrients. In that instance they aren't very fussy. A bit of damp wallpaper or fabric will do fine.
