Then again, most of my experience also comes from places like powerlisting, where people don't necessarily have the firmest grasp on storytelling.

Your character is basically a demigod, so unless he goes entirely braindead, he shouldn't have much of a problem dealing with whatever infestations pop up.  My best bet would be to somehow hide the entirety of the infestation until it basically carpets the place when it finally reveals itself.  So just play a little whac-a-mole with the tunnels, and you'll be set.
