Maple Sap Dripping: Aphids or Cicada Damage?

Diagnosing Sticky Residue

Clear/brown sticky liquid on cars under a sugar maple: check leaves. Sticky leaves = aphid honeydew. Treat with systemic soil-applied insecticide. Non-sticky leaves + cicada egg-laying slits in twigs = sap from cicada wounds. No treatment needed; cicadas won't return for years.
