Articles that take a single question further than an FAQ answer can. The first covers the one with the least obvious answer: a dead-animal smell from inside a wall. Every statement of law or agency guidance carries its source and the date it was read.
Usually a mouse or a rat out of reach in the cavity. How to check above, below and beside the wall, why cutting is often not the first step, and what to expect while it fades.
Looking for the reference pages instead?
Articles here take one question at a time and go into it at length. For the quick version, start with who removes a dead animal in Missouri, the handling and disposal rules, or the locations page for the larger cities and counties.
Check the locations page first for a city or county route that covers it. If there is none, call with your ZIP code and where the animal is.
