A likely entry route needs building-approved exclusion
A gap around pipes, cabinets, doors, or wall penetrations near activity may be part of the route, but sealing must avoid trapping animals or damaging building systems.
Why this result fits
- A gap connects to a wall, pipe chase, cabinet void, or common area.
- Signs cluster along that route.
- The opening is part of the building rather than a movable belonging.
What to do now
Photograph and measure
Document the opening with a ruler nearby without inserting fingers or tools.
Keep the route clear
Move food and loose belongings away if safe, but do not disturb waste or nesting.
Request inspection before sealing
Ask maintenance or pest control to confirm activity and choose a durable, fire-safe, building-compatible exclusion method.
Stop and escalate if
- The gap contains wiring, hot pipes, gas equipment, or active moisture.
- A rodent or nest is inside the opening.
- The opening is in a fire-rated assembly or shared utility chase.
What not to do
- Do not fill holes blindly with foam or fabric.
- Do not seal an animal inside a wall.
- Do not alter pipe, electrical, ventilation, or fire-rated penetrations.
Message you can send to maintenance
A possible mouse entry opening is at [location], approximately [size], near [signs]. Please inspect for activity and use an appropriate building-safe exclusion repair after control is underway.
Help prevent a repeat
- Recheck repaired routes for new signs.
- Keep food away from utility penetrations.
