Mice are one of the most common and problematic pests found in Michigan homes. They are capable of entering structures through extremely small openings and can quickly establish nests inside walls, attics, and basements. Effective mouse control requires more than trapping. It involves identifying entry points, eliminating access, and preventing re-entry.
House Mice
Overview
The house mouse is the most common mouse species found in Michigan homes. They are active year-round and readily nest indoors.
Behavior
House mice are nocturnal and prefer to stay close to food and nesting areas. They reproduce rapidly and can spread throughout a structure in a short period of time. Activity is often highest at night.
How to Identify Them
House mice are small with gray to light brown fur, large ears, and long, thin tails. Common signs include droppings, gnaw marks, nesting material, and scratching sounds in walls or ceilings.
Why They’re a Pest
Mice contaminate food, damage insulation and wiring, and can introduce bacteria into living spaces. Their constant gnawing also poses a fire risk when electrical wiring is damaged.
Common Mouse Entry Points
Overview
Mice can squeeze through openings as small as a dime. Entry points are often overlooked and allow ongoing infestations even after trapping.
Behavior
They follow exterior walls, utility lines, and structural edges until they find access points into the home.
How to Identify Entry Areas
Common entry points include:
Gaps around doors and window frames
Openings around utility lines, pipes, and AC lines
Foundation cracks and siding gaps
Garage doors, especially worn weather stripping
Attic vents, soffits, and roofline penetrations
Why Entry Points Matter
Without sealing access points, new mice will continue to enter regardless of how many are removed. Exclusion is a critical part of long-term mouse control.
