Report Spotted Lanternfly Egg Masses this Winter

New York State could use your help to watch for and report signs of the invasive spotted lanternfly (SLF). This time of year, be on the lookout for SLF egg masses. Freezing temperatures will kill off adult insects, but the egg masses they lay in the fall can be seen throughout the winter. Egg masses tend to be about 1.5 inches long and resemble mud that has dried and cracked. You can find them on just about any flat surface, including vehicles, firewood, outdoor furniture, etc.

If you believe you have found a SLF egg mass, take a photo and note the location. Then report it to the NYS Department of Agriculture and Markets by filling out their online reporting form. Together, we can slow the spread of SLF and catch new infestations early.

    Are the other two white spots lichen? If so, how can people tell them apart?

    Winter months are the best time of the year to spot and remove egg masses. Each egg mass has 30 – 50 eggs. Check around your property and eliminate as much as possible. Attached clip has more information. https://youtu.be/Nwe-2ocs0tk
