The MDARD (Michigan Department of Agriculture and Rural Development) recently sent out a reminder regarding the Spotted Laternfly.
The Laternfly is an invasive pest. As of July 2025 the populations of these plants have been confirmed in Lenawee, Macomb, Monroe, Oakland, and Wayne counties. You do not need to report sightings if you live in these areas. If you live outside these areas and suspect you have seen the Spotted Laternfly take a picture, note the date and location and report it to MDARD.
Adults are approximately one inch long and half an inch wide with tan wings and black spots. When they spread their wings the red and black hindwings are visible. They pose no threat to humans or pets (They do not sting or bite).
They feed on 70 types of trees and plants. These insects feed on the sap from host plants and then secrete a large amount of honey water. This sweet, sugar rich water affects the appearance of plants, sidewalks, and other outdoor surfaces with black sooty mold growth. It also attracts unwanted pests such as yellow jackets, flies, and ants.
If you suspect you have the Spotted Laternfly in your trees or plants call an arborist who is certified in applying pesticides and knowledgeable about the treatment methods. If you choose to treat this yourself be consistent and research the best way to apply pesticides.
