Mold in houses is a health hazard, it's unsightly and also damages materials on which it is growing on. In houses mold can be found growing on walls, ceiling tiles, clothes, shoes, books, foodstuffs, and other valuable items.

What Is The Source Of Mold In Houses?

Mold in houses originates from outside environment in form of airborne spores and fragments. Outside the house, the molds grow on dead plant material (a few of these moulds are also capable of growing on living plants causing diseases) and produce spores which become airborne. The concentration of spores in the outside air reaches peak levels in summer. When we open our doors or windows, the spores and other mold fragments are blown into our houses by wind and settle on various surfaces. If the surface on which the spore has settled become wet, the spores germinate and if the material is organic such as paper, leather, and wood the germinated spores continues to develop into visible mold growth which in turn produces mores spores.

A number of molds are also soil borne. These can be carried into houses by flood water or soiled shoes, implements or other articles.

Frequent vacuum cleaning reduces spore load in houses.
