Ann Arbor’s diverse climate is one of its many charms, offering residents the beauty of all four seasons. However, these changing weather patterns also contribute to the prevalence of mouse infestations in the area. Understanding how Ann Arbor’s weather influences mouse behavior can help homeowners take proactive steps to protect their properties year-round.

Understanding Mouse Behavior in Different Seasons

• Winter Months: As temperatures drop during Ann Arbor’s cold winters, mice seek warmth and shelter to survive. Your home becomes an attractive refuge, providing not just warmth but also ample food sources. Mice can squeeze through openings as small as a dime, making it easy for them to enter through cracks in the foundation, gaps around windows and doors, or vents.
• Spring and Summer: With the arrival of spring and summer, mice begin breeding, leading to population increases. While food is abundant outdoors, factors like heavy rainfall or landscaping changes can drive mice indoors. Additionally, construction and development can disrupt their natural habitats, pushing them to find new shelter inside homes.
• Autumn Transition: Autumn is a critical time as mice start preparing for the upcoming winter. They search for secure places to nest and store food. The cooler weather prompts them to find stable environments, and homes provide the perfect setting. This season often sees a spike in infestations as mice settle in before the cold hits.

Weather Patterns That Influence Infestations

• Heavy Rainfall and Flooding: Excessive rain can flood mouse burrows, forcing them to find drier ground—often inside homes.
• Temperature Fluctuations: Sudden changes in temperature can disrupt mice’s natural habitats, leading them to seek more consistent environments indoors.
• Snow Accumulation: Deep snow can cover food sources, driving mice to forage inside homes where food is accessible.

Preventative Measures for Homeowners

1. Seal Entry Points

• Inspect Regularly: Check your home’s exterior for cracks, gaps, and holes. Pay special attention to areas where utilities and pipes enter the home.
• Use Proper Materials: Seal openings with durable materials like steel wool, caulk, or metal mesh that mice cannot chew through.

2. Maintain Yard Cleanliness

• Trim Vegetation: Keep shrubs, trees, and grass trimmed away from your home’s exterior to eliminate easy access routes.
• Remove Debris: Clear out leaf piles, wood stacks, and other yard debris where mice might nest.

3. Secure Food Sources

• Indoor Food Storage: Store pantry items in airtight containers. Regularly clean up crumbs and spills.
• Outdoor Attractants: Keep garbage bins sealed and consider using rodent-proof bird feeders.

4. Reduce Clutter

• Indoor Clutter: Minimize clutter in garages, basements, and attics where mice can hide and nest.
• Storage Practices: Use plastic storage bins with tight-fitting lids instead of cardboard boxes.

5. Address Moisture Issues

• Fix Leaks: Repair leaking pipes and faucets promptly.
• Improve Drainage: Ensure gutters and downspouts direct water away from your home’s foundation.
