Warm, Dry Winter Means More Mice, Scientists Say | News

The unusually warm, dry winter Minnesota has seen this year has meant a growing problem with mice.

According to University of Minnesota Urban Entomologist Stephen Kells, a typical winter kills approximately 50% of the mice population each year in what is known as "winter kill."

But this year, without the typical "winter kill," more mice are surviving inside, then making their way inside. Kells estimates the mice population to be 10% to 15% larger this winter as compared to a typical Minnesota winter.

According to the Centers for Disease Control and Prevention, mice can carry fleas, ticks and other parasites. They can also transfer foodborne illnesses and dozens of other diseases.
