“…while inactivated by the fumigation treatment, still remains toxic at the tested dosages.”

Charkravarty, P.; Evaluation of Five Antifungal Agents Used in Remediation Practices Against Six Common Indoor Fungal Species; Journal of Occupational and Environmental Hygiene

“It is very important that fungal growth be physically removed and contained to prevent cross contamination of the living space. Attempts to kill or inactivate fungal growth and spores with products such as fungicides, heat, or fogging does not eliminate spores.”

New York Committee for Occupational Safety & Health. Guidelines for Mold Remediation (Removal)

Disinfectants are usually not needed because physical removal of fungal growth is the most effective way to prevent exposure.

The use of gaseous, vapor-phase, or aerosolized (e.g. fogging) biocides for remedial purposes is not recommended. Using biocides in this manner can pose health concerns for people in occupied spaces of the building and for people returning to the treated space. Furthermore, the effectiveness of these treatments is unproven and does not address the possible health concerns from the presence of the remaining non-viable mold.
