Michigan officials are urging residents to squish and report an invasive species that was initially discovered in the state last year, as the insect is expected to reappear. This species, known as the spotted lanternfly, feeds on the sap of various plants and crops.
Its presence in the state was officially confirmed on August 11, 2022, by Gary McDowell, the Director of the Michigan Department of Agriculture and Rural Development. A small population of these insects was found in Pontiac, located in Oakland County. At that time, McDowell expressed concern about the potential negative impact on Michigan's grape industry. In addition to grapes, the spotted lanternfly poses a threat to over 70 different types of crops and plants. This includes apples, hops, and hardwood trees, according to the Michigan Department of Natural Resources (DNR). While native to Asia, this pest arrived in Pennsylvania in 2014.
More Spotted Lanternfly Damage
The damage caused by the spotted lanternfly occurs as it feeds on plant sap, secreting a sugary substance called honeydew. This honeydew accumulates on the ground and nearby vegetation. This leads to the development of a black mold that not only discolors but also kills plants. Moreover, the honeydew attracts other insects, including hornets and ants, which can further complicate the process of harvesting crops.
Although spotted lanternflies have limited flight abilities, they can easily hitch rides on items like firewood, tires, campers, and vehicles. They also lay eggs extensively in various locations, as highlighted by the DNR. These eggs resemble patches of old chewing gum.
What to do if you see a spotted lanternfly
If you come across a spotted lanternfly egg mass, nymph, or adult, the DNR requests that you take photographs and note the date, time, and location of the sighting. The next step is to report the sighting to the Michigan Invasive Species Information Network through their website or mobile app. Furthermore, you can effectively control the infestation by scraping egg masses into a plastic bag containing hand sanitizer or rubbing alcohol to eliminate them and limit their spread within Michigan.
The DNR provided the following recommendations to stop the spread:
- Inspect your vehicle: Prior to leaving a parking area, thoroughly examine your car for spotted lanternfly eggs or insects. Check areas like doors, sides, bumpers, wheel wells, grills, and roofs. If spotted, eliminate any eggs or insects by squishing them.
- Close windows when parking: Spotted lanternflies and their nymphs might enter vehicles without detection.
- Eliminate host trees: These insects favor the ailanthus tree, commonly referred to as the "tree of heaven." To prevent drawing spotted lanternflies, consider removing such trees from your property.
