Debugging A House: What Rodent Exclusion Taught Me About Root Cause Analysis

Rodent Control Inc. — Mon, 20 Jul 2026 12:27:25 +0000

We do rodent control across California, and the job is closer to debugging than most people expect.

A customer calls because they hear scratching in the attic. The obvious fix is to remove what is making the noise. Set traps, catch the rats, problem gone. Except it is not, and it comes back in a fortnight, because catching the rats treats the symptom and not the cause.

The cause is a gap somewhere in the building envelope, often no wider than a quarter. Until that is closed, you are not fixing anything, you are just clearing the queue faster than it fills.

The parallel to software is almost exact. Restarting the service clears the symptom. It does not tell you why memory climbed in the first place. If you never find the leak you will restart forever and call it maintenance.

What the job actually looks like:

1. Reproduce. Where is the noise, at what time, how often? Roof rats are nocturnal and follow fixed routes, so the pattern tells you where to look.

2. Trace the path. They climb: branches to the roof, cables, the gap where a pipe enters the wall. You follow the evidence, which is droppings and greasy rub marks along the route.

3. Fix the root cause. Seal every entry point, not just the one you found first.

4. Clean up the state it left behind. Contaminated insulation comes out.

5. Verify. If it returns through something you sealed, you did not fix it.

The failure mode we see most often is someone doing step 1 and step 5 and skipping the middle. That is a house running on restarts.
