The mouse appears diminutive, its coat a soft gray that reflects a subtle sheen. Eyes are black, wide, and alert, conveying heightened vigilance. Ears are proportionally large, rotating independently to capture ambient sounds. The tail is slender, tapering to a fine point, and often held in a relaxed curl.. Date latest changes:
Safely Removing a Mouse Stuck in a Suspended Ceiling
Mice become confined in suspended ceiling spaces for several predictable reasons. Their small size and natural tendency to explore tight openings allow them to enter and remain hidden where access is limited. Gaps around HVAC ducts – Unsealed joints or damaged ductwork create entry points that lead directly into the plenum.. Date latest changes:
How to catch a mouse in an apartment without using a mouse trap
