Spotted lanternfly egg masses look like a smear of gray putty stuck to bark, fence posts, or even outdoor furniture. Late summer is when adults start laying, so now is the time to start checking trunks closely.
They feed on the sap of a wide range of hardwoods, weakening a tree gradually over several seasons rather than causing damage all at once. Maples, black walnut, and tree-of-heaven are common targets in our area.
Scraping egg masses now, before they overwinter and hatch in spring, is one of the most effective things a homeowner can do. For heavier infestations, a professional monitoring plan makes sense.
Have you spotted any spotted lanternflies or their egg masses on your property this season?
