V, the chlorine, even better when mixed with ammonia!, is fine and dandy but the guy is dead already. I want to collapse the gallery so it is uninhabitable. More of a pipe dream really since a major part of the gallery is under my shed and my and my contiguous neighbor's lawns and gardens. The last infestation was a few years ago and my neighbor at the time gassed them in their dens. I think the corpses kept the galleries vacant for a few years. Anyway, shooting them is all good fun and practice for the Woodchuck Zombie Apocalypse.
Ortho, thanks for the offer to help with my quackulations.
