I've had spore contaminated cases like that which gave me an asthma shock, no kidding. That stuff is vile if you're an allergic like me. Basses stink then too - my Triumph had that incense stench for a year or so (all the while standing exposed in a stand), but it eventually went away. Ultraviolet rays are a good idea. Yes, they bleach out the "fur" in the case, but who cares. Spores don't like it. And once they're dead, vacuum them out.
