Why is specialist application method fogging deemed inadequate for serious infestations?

It might only treat the surface mold it settles upon and fails to address hidden or embedded growth within porous materials.

Fogging, which involves releasing the treatment product into the air via a machine, is often dismissed by specialists for serious mold problems because its distribution is inherently superficial. Airborne distribution means the product primarily contacts surfaces where the mist settles directly. Serious mold infestations, however, frequently involve growth embedded within porous building materials such as wood framing or drywall interiors, where the mold roots or hyphae have penetrated deeply. Since the fog cannot penetrate these dense materials effectively, it leaves the hidden colonies untouched, allowing the infestation to persist and re-emerge once surface conditions stabilize, thereby failing to resolve the root cause of the widespread biological activity.
