Vinke,
Have never seen a publication that suggests that scientifically, though as you know there are scant documents even relating
to mitigation of bat guano and bird droppings and they stem from OSHA or CDC or a combo of both.
Neither of these outfits who put out the only real information are likely spending any funding on testing alternate methods of
mitigation or clean up related to histoplasmosis. Disease wise for CDC there are too many true threats to our health and emerging
threats to bother with something like histo that such a high percentage of our citizens have antibodies for showing they were exposed
and never developed anything life threatening, though some mortalities do occur.
On the "this seems logical" end of things, if you blow in 4-12" or more of modern cellulose insulation and completely entomb or cover
over a "small" (we all likely have a pic in our minds of what a small amount of guano is) pile of guano in an attic, that remains dry and undisturbed,
it would be unlikely without someone walking through it and stirring up the buried guano that it would become airborne which of course
would be the necessary route for us to inhale it as human beings.
A further step would be that though we treat all guano and bird droppings as though they could have histoplasmosis spores, ultimately not all
do and the percentage should vary based on a myriad of factors required for their propagation.
Last time I looked for anything new on histo was over a year ago, but again, when you have high level high mortality emerging diseases in foreign countries
and even things like west nile virus and others here that take more people every year, I doubt any of the major institutions is performing much in the way of
new research on histo...
Just my nickel on this, I'll be interested to see what anyone else has to say on this just out of curiosity.

I would add though, if a small amount and reachable, why not remove it, unless this is a strange circumstance and you want to leave out guano mitigation or removal and go with "encapsulation" via the blown cellulose... Of course the other thing going through my mind is that you've seen someone who has already done this and is stating it encapsulates and your wondering if they are out to lunch....
Anyway. .05
