Mice & Rats in Wisconsin

Weather-driven mice & rats risk forecasts for Wisconsin cities and counties.

Mice and rats are among the most common fall and winter pests in Wisconsin. Our rodent forecasts predict when dropping temperatures and rain will push mice into homes, garages, and outbuildings seeking shelter.

Seasonal Pattern

Rodent pressure in Wisconsin increases sharply from September through November as temperatures drop. Mice seek indoor shelter before the first hard freeze. A second peak occurs during mid-winter cold snaps. Spring activity focuses on outdoor foraging and breeding.

Weather Influence

The primary driver of indoor mouse entry is cold weather — temperatures below 55°F trigger strong shelter-seeking behavior. Rain compounds this by making outdoor conditions uncomfortable. Forecast freezing nights are the strongest predictor of new indoor rodent activity.
