The Michigan Department of Agriculture and Rural Development (MDARD) has confirmed the presence of spotted lanternfly populations in several counties across southeast Michigan, raising concerns about the potential impact on the state's agriculture and natural resources in 2026.

Why it matters

The spotted lanternfly is an invasive pest that feeds on a variety of plants, including grapevines, black walnut, maple, willow, birch, and sumac trees. As the populations continue to spread, they pose a significant threat to Michigan's wine industry and the overall health of the state's trees and forests.

The details

In 2025, MDARD detected spotted lanternfly populations in Jackson, Lenawee, Macomb, Monroe, Oakland, and Wayne counties. With established populations across the region, the agency expects the pest to spread further in 2026 along highways, shipping routes, and anywhere people move items, which could lead to widespread damage to plants and trees.

  • In 2025, MDARD confirmed the presence of spotted lanternfly populations in several Michigan counties.
  • MDARD is warning that 2026 could see a significant expansion of the spotted lanternfly's reach across the state.

The takeaway

The spotted lanternfly's continued expansion in Michigan poses a serious threat to the state's agriculture, particularly the wine industry, as well as the overall health of its trees and forests. Vigilance and coordinated efforts will be necessary to mitigate the impact of this invasive species in the coming year.
