Rodent Activity in Autumn and Early Winter: What Indiana Homeowners Need to Know

 “Don’t hire the big guys, hire the right guys.”

Why Rodents Invade Indiana Homes in the Fall

As temperatures drop across Evansville, Boonville, Newburgh, Chandler, Poseyville, and nearby communities throughout Warrick, Vanderburgh, and Posey Counties, rodent activity increases dramatically. Fall and early winter are peak seasons for mouse infestations and rat intrusions as rodents search for warm, safe shelter inside homes, garages, barns, and businesses.

Why Rodent Activity Spikes in Autumn and Early Winter

1. Cold Weather Drives Rodents Indoors

When nights turn chilly, mice and rats begin searching for warmth. Homes and commercial buildings offer ideal temperature stability, protection, and food sources.


2. Natural Food Supplies Decline

Seeds, insects, and vegetation diminish as fall progresses, pushing rodents to seek out pantries, kitchens, garages, and storage areas.


3. Peak Population Season

Young mice and rats disperse in the fall, looking for nesting sites—making this the most common time for homeowners to notice activity.

Signs of Rodent Activity in Your Home

•           Droppings in cabinets, basements, attics, and garages

•           Scratching or scurrying noises in walls or ceilings

•           Chewed wires, insulation, or food packaging

•           Grease marks or rub trails

•           Shredded nesting materials

•           Strong ammonia-like odors

Why Ignoring Rodents Is Dangerous

Rodents cause:

•           Electrical fire risks from chewed wiring

•           Contaminated food and surfaces

•           Damaged insulation and stored items

•           Structural issues from gnawing and nesting

A small fall problem can become a severe winter infestation quickly.


How Indiana Homeowners Can Prevent Rodents This Season

Seal Entry Points

Close gaps in siding, foundations, soffits, and door sweeps.


Remove Food Sources

Store food in sealed containers and clean up spills.


Clean Outdoor Areas

Move firewood, reduce clutter, and manage vegetation.


Watch for Activity Early

Addressing rodent signs early saves money and prevents structural damage.
