Spotted lanternfly has established itself in Frederick County, and early summer is when the nymph stage becomes most visible and most active.
While spotted lanternfly doesn't kill trees directly, the damage it causes is cumulative and significant. The insects feed heavily on sap from tree-of-heaven, black walnut, red maple, apple, and a number of other Maryland species, weakening trees over repeated seasons and leaving a sticky honeydew residue that promotes sooty mold. Trees already stressed by drought, heat, or disease are particularly vulnerable.
Physical removal of egg masses in late winter is the most effective control step, but if you missed that window, now is the time to be watching your trees and your property for signs of infestation.
