If you haven't heard about spotted lanternfly and you live in Frederick County, it's time to get familiar. The spotted lanternfly (Lycorma delicatula) has established itself in Maryland, and Frederick area properties are well within its current range. It feeds on a wide range of trees and plants, and while it prefers tree of heaven, it also attacks maples, black walnut, birch, cherry, and willow — trees that are common across Western Maryland landscapes.
The damage mechanism is what makes it a real concern for your yard. Spotted lanternflies feed by tapping into a tree's vascular system and extracting sap. They excrete a sticky residue called honeydew that coats the surfaces beneath the tree and promotes sooty mold growth. Heavy infestations weaken trees over time, reduce their vigor, and make them more susceptible to other stressors — drought, disease, and secondary pest pressure.
Right now in late April and May, adults are in the nymph stage and egg masses from last year's population may still be present. If you're seeing them or finding egg masses on smooth-barked trees (they look like gray putty smeared on bark), it's worth noting where and how many. Maryland residents are encouraged to report sightings and destroy egg masses when found. On a heavily infested property, professional assessment of affected trees can help determine what, if anything, needs intervention.

A photo of a spotted lanternfly or egg mass on tree bark would be the most effective visual — these are widely recognizable and stop the scroll. If no job photo is available, a photo of tree sap damage or honeydew residue on bark from a Frederick property works well. Note: spotted lanternfly images are widely available as public domain from USDA sources — check with Al before using any non-job photo. Authentic job documentation preferred.
