Natural Habitat

Native to Asia but invasive worldwide; often found in residential homes seeking warmth during colder months, as well as in orchards and gardens.

Risks & Benefits

Risks: A major agricultural pest causing significant crop damage; a nuisance to homeowners due to smell and overwintering habits. Benefits: None significant in non-native ranges, though they are prey for some birds and generalist predators.
