The scratching is coming from behind your Los Angeles bedroom wall. You are ready to approve treatment, but then you picture a rat dying where no one can reach it. It is a reasonable concern. The method used, where treatment is placed, and how captures are monitored can affect that risk; no rat removal service can guarantee where a rat will die. What we can do is inspect first and discuss a plan that takes access and retrieval seriously.
Hearing movement in a wall tells us where you noticed activity, not necessarily where the rats enter, travel, or can be intercepted. We look for signs of activity and possible routes through areas such as attics, garages, and crawlspaces, as well as accessible spaces near the affected wall. The findings for your home should guide where treatment can be placed and how it can be checked without assuming a capture inside the wall is the only option.
If bait is proposed, ask where it would be used, how it would be secured, what exposure precautions apply, and how its use affects the possibility of a rat dying out of reach. California restricts many uses of anticoagulant rodenticides, but that does not mean every bait is banned. Any proposed product and placement need to be assessed for the home, the household, and applicable rules. We would rather explain a specific plan than offer a blanket assurance about hidden carcasses.

Settle the practical details before treatment begins
A useful conversation with us connects each treatment choice to your original question: if there is a capture—or an odor—how will we know, and what can we reach? Before you approve work, ask us to spell out the proposed plan and confirm its follow-up terms.
- Method and placement: What will be used, where will it go, and what inspection findings support those locations?
- Checks and retrieval: How often will activity and captures be checked, and which treatment locations can be accessed for retrieval?
- Household precautions: What should children and pets be kept away from, and for how long under the proposed method?
- Odor response: Whom should you contact if a smell starts, how will its source be investigated, and what retrieval and cleanup are included in the agreed service?
For a landlord or property manager, it also helps to establish who can authorize access if an odor is reported by an occupant. Check frequency, access arrangements, and cleanup coverage should be clear before treatment starts, not guessed at after a problem appears.
Removal needs checks before access is closed
Once active routes are identified, removal is not simply a matter of setting treatment and walking away. The plan needs a way to monitor activity, check accessible captures, and respond to what those checks show. If scratching continues or signs appear elsewhere, that information may change where we investigate next. Checking also creates an opportunity to retrieve captures before they become an odor problem.
Closing an entry point is important for preventing a return, but sealing too early while rats may still be inside can complicate removal and limit access. We want to establish whether activity has stopped before closing access, then address affected areas and cleaning needs identified during the job. That sequence protects the long-term result without treating a quiet wall as proof that every rat is gone.

If an odor starts during treatment
Who should you call, and what happens next?
Contact the person named in your service plan promptly and tell them when and where you first noticed the smell. An odor may call for another inspection to narrow down its source; it does not, by itself, pinpoint a carcass behind the wall. Depending on what the investigation finds, retrieval may require access that was not apparent at the outset, and some locations may remain difficult to reach. Ask in advance who will discuss any access decision with you and which retrieval and cleanup work your agreed terms cover.
At 360 Rodent Control, we want you to raise the hard-to-reach-wall concern before treatment, not feel stuck with it afterward. Ask us for an inspection-led plan for your home that explains the likely routes, family and pet precautions, monitoring arrangements, and what happens if an odor develops.
