What Is Mildew On Walls. What can be used to kill and treat mold? Mildew is the name for the most common type of black mould on walls, characterised by spots that can then spread over larger areas if left unchecked.
Mould on walls develops when mould spores hit damp walls.
One of the most important ways one can tell mold from mildew is how each fungus looks. Moulds appear in shades of black, blue, red, and green, whereas mildew is white. Mildew is also sometimes found on the floors, walls or ceilings of areas with lots of humidity, such as bathrooms, kitchens or basements. The white mold/mildew on my two dressers developed after i used a spray insecticide a number of times along the baseboards behind those dressers.
