Michigan is strengthening its efforts to manage the spread of spotted lanternfly, an invasive insect that continues to expand into new areas of the state. Recently, the Michigan Department of Agriculture and Rural Development confirmed a spotted lanternfly population near Niles in Berrien County, marking the first confirmed population in southwest Michigan.
First detected in Michigan in 2022, spotted lanternfly feeds on more than 70 plant species and is especially attracted to tree of heaven. Large populations can become a nuisance in neighborhoods and communities, while also posing risks to important agricultural crops such as grapes and hops.
To address this growing concern, researchers and educators from Michigan State University Extension are working with residents, growers, and government agencies to detect new infestations, slow the insect’s spread, and prepare communities for future challenges.
One of the most innovative tools being promoted is the “lampshade” trap. Developed with guidance from research conducted by Deborah McCullough, MSU Forestry Entomology Researcher, and Tim Harrison, the trap is designed to attract female spotted lanternflies seeking locations to lay eggs. Research found that approximately 80% of egg masses at study sites were deposited on these traps, even when insect populations were relatively low.
The lampshade trap is inexpensive, easy to build, and does not require insecticides. Unlike sticky traps, it does not capture beneficial native insects. At the end of the season, egg masses collected on the trap can be removed and destroyed before hatching.
Encouraging public participation is another important part of the management effort. Lindsey Kerr, MSU Extension Consumer Horticulture Educator, has been conducting workshops across southeastern Michigan to help residents identify spotted lanternfly, recognize tree of heaven, and learn how to build and install lampshade traps.
Kerr believes community awareness can play a significant role in slowing the pest’s spread. These educational programs provide practical knowledge and encourage residents to actively monitor their local environments.
Community members have also become involved in outreach efforts. Kelly Konieczki, Grosse Pointe Park Resident, reported spotted lanternfly sightings and later participated in educational workshops. She now helps lead community programs aimed at increasing awareness and encouraging public involvement.
She said, "I also really valued the opportunity to connect with experts, as well as other community members."
Konieczki further emphasized public engagement by saying, "I want to empower others to make a difference and help them understand that science is for everyone. Any time I can connect with people in person and offer hands-on experiences, my hope is that it will leave them inspired to get involved."
The concern extends beyond residential areas. Michigan’s grape industry is particularly vulnerable to spotted lanternfly infestations. Heavy populations can weaken vines, lower fruit quality, and reduce future yields. Michigan’s vineyards cover more than 13,000 acres and contribute significantly to the state’s economy.
According to Rufus Isaacs, MSU Extension Berry Crops Entomologist, growers should remain vigilant and continue monitoring vineyards and nearby host plants. He stated, “The recent detection of spotted lanternfly in southwest Michigan is a new region of the state and in a county with many grape growers. Thankfully, these spotted lanternflies were found in a park and not on a crop, but growers should continue to monitor for this invasive pest on tree of heaven and their grapevines as they go about their fall activities.”
Michigan State University Extension is also educating gardeners, landscapers, and flower growers. Caitlin Splawski, MSU Extension Floriculture Educator, has been teaching participants how to recognize invasive pests and report sightings. These efforts help improve early detection and support statewide monitoring programs.
Experts encourage residents to watch for spotted lanternfly adults and egg masses, report sightings, inspect vehicles and outdoor equipment, and learn how to identify tree of heaven. Public reports have already played a major role in detecting new populations across the state.
As spotted lanternfly continues to spread, cooperation among researchers, farmers, gardeners, and community members remains essential. Through education, monitoring, and practical management tools, Michigan hopes to slow the insect’s expansion and reduce its impact on agriculture, natural resources, and local communities.
