Stop Elm Leaf Miner Damage Before It Starts

Elm leafminers are tiny insects that live inside elm leaves and feed from within—causing brown, dry, papery spots and early leaf drop. If left untreated, they can weaken the entire tree year after year. Utah Tree Care recommends early action: planting resistant tree varieties and applying systemic insecticides before damage becomes visible. Once the leaves turn brown, it’s often too late to treat effectively. Protect your trees by spotting signs early and scheduling professional care.
