The most desirable way to collect mold samples is to use transparent sticky tape. Sample collection is relatively simple so that it can be conducted by professionals and homeowners. An approximate two-inch strip of tape should be pressed to the surface of infested material. It should then be transferred to a standard microscope slide. I have had good results with tape fastened to plastic, metal or glass when homeowners have sent me samples.
Standard practice is to provide a laboratory report of results to individuals submitting the sample.
If your home inspector did not provide you with a laboratory report confirming that Stachybotrys was present, you should request one. If no such report exists, the home inspector s conclusion should not be accepted. As such, a second more qualified opinion is in order. Growth requirements for Stachybotrys are quite distinctive. Interestingly, it is not commonly found on wood.
