How Calgary's Construction Boom Is Increasing Rodent Activity
Calgary's rapid growth means more construction—and more displaced rodents seeking new homes. Here's what homeowners need to know.
The Construction-Rodent Connection
When developers break ground on new communities, they disturb established rodent habitats. Mice and rats that lived in fields and natural areas are suddenly displaced, and they need somewhere to go.
These rodents don't travel far—they move to the nearest available shelter, which is often nearby established homes. Homeowners in communities adjacent to new developments are seeing significant increases in rodent activity.
The Numbers
Properties within 500 meters of active construction sites report 3x higher rodent activity compared to areas without nearby development.
Most Affected Calgary Areas (2025-2026)
- Seton & Mahogany (SE)
- Livingston & Cornerstone (NE)
- Glacier Ridge & Rockland Park (NW)
- Belmont & Pine Creek (SW)
- Legacy & Walden (SE)
Signs of Displaced Rodents
- New scratching sounds in walls after nearby construction starts
- Droppings appearing in garage or basement
- Gnaw marks on stored items
- Sightings of mice during daylight (indicates large population)
What You Can Do
Seal Entry Points
Mice can enter through gaps as small as a dime. Check foundations, utility entries, and garage doors.
Remove Attractions
Secure garbage, clean up fallen fruit, and store pet food properly.
Monitor Activity
Set up monitoring stations to catch problems early before populations establish.
Act Quickly
One pair of mice can produce 60+ offspring per year. Early intervention is critical.
