Maple Honeydew Deluge: Neighborhood-Wide Aphid/Scale Outbreak

First summer with extreme sticky drippings from maple covering yard, driveways, neighbors' cars. Multiple maples on street all affected. Asks if seasonal, weather-related, when it stops.

Cause: Aphids or Scale

Sucking insects → honeydew → sooty mold.

Solution for Large Trees

Soil systemic: Imidacloprid (Bayer Advanced Garden Tree & Shrub Insect Control) — best coverage, lasts months. Spraying large trees impractical.
