So, we apparently have had a rodent or some other critter die inside one of the interior walls in our guest bathroom. The odor is terrible. I've been under the house and confirmed it's not coming from the crawlspace, so it must be inside one of interior walls though I cannot pinpoint which one. We had a pest control guy come out. He did the same sort of inspection I did and couldn't find it, either. He basically told me that he's had folks ask him to knock a bunch of holes in their drywall in the past, and still been unable to locate the source. His advice was just to let it runs its course and that the smell will dissipate in time. At this point, I have the room closed off and running the ventilation fan 24/7. I put several odor-absorbing pouches inside but not sure if they are actually helping. At this point, I can't think of a better plan than what he suggested but to the group, anything I'm missing?Thanks,
Erik
