Maple Dripping Sap: Aphids or Scale and Systemic Fix

Sticky Sap = Insect Honeydew

Your 8-year-old sunset maple dripping sticky sap with bees/wasps attracted means sap-feeding insects (aphids, soft scales, or whiteflies) are excreting honeydew. Sooty mold may follow.

Solution: Soil Systemic

Bayer Advanced Tree & Shrub Insect Control (imidacloprid) applied to soil:

Roots carry to leaves/twigs
Insects die when feeding
Season-long control
No spray drift or coverage issues

Application

Follow label rates (based on trunk diameter)
Apply to moist soil, water in
Allow 2-3 weeks for uptake

Result

Honeydew stops → sooty mold disappears → bees/wasps leave → clean patio/pool.
