Can mice climb walls?
Yes. Mice are excellent climbers and move easily through wall cavities, plumbing pipes, and spaces between floors. This is why nighttime noises in walls or ceilings are a classic sign of infestation.

With professional intervention including sealing off access points, allow 7 to 21 days. Without sealing, mice typically return within 2 to 4 weeks.
