Where it appears
In Toronto properties, pest pressure often follows food, warmth, moisture, storage and access routes. Condos and commercial spaces may also involve shared walls, service rooms or neighbouring activity.
Preliminary identification
House Mouse
House Mouse identification should be treated as a preliminary visual estimate until a technician confirms the evidence.
Common signs
Repeated sightings or evidence in the same area
Activity near food, moisture, storage or exterior access
Signs that return after cleaning or temporary fixes
Unclear evidence that needs inspection confirmation
What to do now
- Keep droppings undisturbed for inspection if safe, or take clear photos before cleanup when immediate sanitation is needed.
- Check door sweeps, pipe penetrations, utility gaps and storage edges, but avoid sealing suspected access before the travel path is understood.
What not to do
Avoid spraying over evidence, sealing active entry points or discarding useful samples before inspection. Those steps can hide the pattern a technician needs to confirm the pest.
