Residents of a shared house in Vancouver, Canada, recently endured an extensive mouse infestation that persisted for nearly a year, illustrating the challenges of controlling rodent populations in multi-occupant urban dwellings.

In the winter of 2023, occupants of the nine-person household first noticed signs of rodent activity when one housemate heard rustling noises emanating from the ceiling of her basement bedroom. Reports of mouse sightings soon followed across the property, including a resident waking to the sound of a bedroom bin being disturbed. The infestation quickly escalated, severely impacting the residents’ quality of life and prompting multiple attempts at extermination.

The tenants described frequent encounters with mice throughout the home, including sightings in common areas such as the kitchen. Food contamination became a daily issue, with cupboards regularly gnawed and bread left with large holes. Several residents reported difficulty sleeping due to the persistent sounds of rodents moving above their rooms, and one occupant even experienced a mouse falling onto her face when hitting ceiling panels to scare them away.

Despite hiring professional pest control services and implementing physical barriers like steel wool to block entry points, the infestation persisted through changing seasons. The rodents grew increasingly bold, at times approaching residents unafraid before being shooed away. One particularly notable incident involved a housemate waking to find a mouse chewing on their hair.

The infestation appeared to subside coinciding with changes in the household rather than through any single successful eradication effort, underscoring the resilience of mice once established indoors. The experience left a lasting impression on the occupants, highlighting both the difficulty of dealing with urban rodent populations and the potential scale of infestations that may begin with a single animal.
