Terrible "sap" on cars/driveways = honeydew from aphids or scales on area maples. Sticky, sugar-rich, attracts sooty mold.
Apply Bayer Advanced Tree & Shrub Insect Control (imidacloprid) as soil drench to each tree. Roots translocate to canopy—kills feeding insects. Season-long control.
Product: Bayer Advanced Insect Control
