Deer Mice in Calgary – Are They Harmful?

Deer mice are common in Calgary, especially in rural and suburban areas. As the weather gets colder, these small rodents often seek warmth inside homes, garages, and sheds. While they may look harmless, deer mice can pose serious health and property risks if left unchecked.

Why Deer Mice Are a Concern

Unlike house mice, deer mice are known carriers of Hantavirus, a rare but potentially severe respiratory illness transmitted through contact with their droppings, urine, or saliva. When contaminated materials are disturbed—such as during cleaning—airborne particles can spread the virus. Proper protective equipment and professional cleanup are essential if deer mice are found indoors.

Signs of Deer Mice Infestation

• Small, rice-sized droppings in cupboards, basements, or attics

• Gnaw marks on food packaging or wiring

• Shredded paper or fabric nests in hidden areas

• Noises in walls or ceilings at night

Prevention and Control

• Seal entry points: Close gaps around doors, vents, and foundations.

• Store food securely: Keep all food and pet food in sealed containers.

• Reduce clutter: Eliminate nesting spots in garages, basements, and storage areas.

• Professional treatment: A licensed pest control technician can inspect, safely remove droppings, set traps, and apply exclusion measures to prevent re-entry.
