Rodent species recorded in Michigan

House mouse (Mus musculus) — Enters at 1/4 inch; 5-10 litters per year; eats about 200 small meals a night.
Norway rat (Rattus norvegicus) — Burrowing rat of basements, sewers and ground floors; tail shorter than head plus body.
Deer mouse (Peromyscus maniculatus) — Primary U.S. hantavirus carrier; lives throughout Washington and the interior West.

When rodents are busiest in Michigan

Rodents push into Michigan structures in fall; hantavirus exposure clusters in spring and summer cleanouts.

Michigan had no confirmed human hantavirus case until 2021, so the routine risk is contamination and structural damage.

For context, nationally

1/4 inch (the width of a pencil) — Smallest gap a mouse can enter. CDC
890; 35% fatal; 94% west of the Mississippi — Hantavirus cases reported since 1993 (through 2023). CDC
