Mac Pearce is an environmental health consultant in St. Paul, Minn.
Q: I've come across a product that was created to combat the anthrax spore and was later found to be effective against mold as well. It's fogged throughout the job for 24 hours, with no access allowed. The product is said to eradicate mold, not just put it in a dormant state. Does this work?
Even if it isn't a problem (and it might be), do you really want to try to persuade a client that it's no big deal?
You bet it can: When it comes to this pervasive fungus, a little can go a long way toward wrecking a job.
