It might work but why guess? I'd be more inclined to identify the culprit and deal with it directly. If you can isolate areas that contain the offending fungi and spores you could make contact with someone knowledgeable, perhaps at a university in your area with a good biology department or forestry department. If they could grow the material they could help evaluate the effectiveness of various toxic remedies. Most home inspectors do not have specific knowledge, the have opinions.
It may well be that something else is easier to apply and more effective than cyanoacrylates. A quick Google search yielded the site below that suggests that for at least one species borates are effective.
