The Michigan Department of Agriculture and Rural Development (MDARD) is asking area residents to watch for the invasive spotted lanternfly this summer.
As of June 2026, spotted lanternfly populations have been confirmed across southeastern Michigan, including areas close to Chelsea, such as parts of Jackson County. While populations are currently low, the insect is expected to become more widespread over time.
“Spotted lanternfly does not pose a risk to human or animal health, but it can be a major nuisance for Michiganders who enjoy spending time on their patios, in their gardens, or in the great outdoors,” said MDARD Director Tim Boring. “We’re asking Michiganders to help slow the spread of this unwanted pest by understanding what spotted lanternfly insects and egg masses look like, checking for the pest after you’ve been out on the trails or in your garden, and reporting new populations via the online Eyes in the Field tool.”
Spotted lanternfly generally does not kill plants, but heavy infestations can stress plants and cause localized damage.
What to do if you see spotted lanternfly
If you see spotted lanternfly while in Jackson, Lenawee, Macomb, Monroe, Oakland, or Wayne Counties:
- Squish it. MDARD is already monitoring confirmed populations in these counties and does not need a report.
- Use traps or insecticidal soaps and oils in areas where spotted lanternfly is most abundant.
- Contact a certified pesticide applicator for large infestations. If applying pesticide yourself, follow label instructions and wear appropriate protective equipment.
If you see spotted lanternfly in any other Michigan county, including Washtenaw:
- Take photos, note the date, time, and location, and submit a report using the Eyes in the Field tool.
How to identify spotted lanternfly:
- Nymphs are black with white spots, turning red with black spots as they develop. Look for nymphs from May through September.
- Adults are roughly one inch long and half an inch wide, with tan forewings marked by black spots. When wings are unfolded, distinctive scarlet hindwings become visible. Look for adults from August through October.
Spotted lanternfly prefers to feed on the invasive tree-of-heaven, but also feeds on grapevines and trees, including black walnut, river birch, willow, sumac, and red maple. When feeding, it produces a sticky liquid called honeydew that can lead to sooty mold growth, discolor plants, leave surfaces sticky, and attract flies and yellow jackets.
