Mold Library

Complete Mold Library - Common Mold Species

 

There are many different types of mold species on this Earth—some toxic, others harmless. At Mold Busters, we believe that important mold-related information should be readily available to and easily accessible by the public.

Our team has created a database of the most common species of mold found indoors so that residents of Ottawa, Montreal and surrounding areas can learn about various molds—what they look like, where they grow and how hazardous they are to human health.

Access to the mold library is FREE and extremely valuable. For more information about any of the molds listed in the library, call us and talk to a mold expert.
