Spotted lanternfly confirmed in Berrien County

The Michigan Department of Agriculture and Rural Development, in partnership with the U.S. Department of Agriculture, confirmed a population of spotted lanternfly (Lycorma delicatula) in Berrien County. Monitoring was conducted by the Southwest x Southwest Corner Cooperative Invasive Species Management Area, with funding from MDARD to support trapping and surveillance efforts. Spotted lanternfly generally does not kill plants, but heavy infestations can stress plants and cause localized damage, potentially impacting crop yields if infestations occur.

MDARD Director Tim Boring noted that the detection helps prepare fruit growers to spot this invasive pest. Berrien County is a major grape‑producing region of Michigan, and although the detection was not found in a vineyard, MSU Extension urges producers in the area to remain vigilant and alert for spotted lanternfly. Producers are encouraged to monitor for signs of the pest and report findings.

The new population in Berrien County joins confirmed populations in Jackson, Lenawee, Macomb, Monroe, Oakland, Washtenaw, and Wayne counties. Michigan’s Invasive Species Watch List Viewer enables residents to see where spotted lanternfly has been confirmed across the state. Since the first detection in 2022, MDARD and its partners have monitored more than 100 locations throughout Michigan.
