Variegated Maple, Sticky Deposit

Guysgrandpa added on July 3, 2015 | Answered

Our variegated maple drops tiny sticky deposits on cars parked beneath it. The leaves look quite shinny and are slightly sticky. Is this something that can be treated?

Maples are susceptible to the cottony maple scale, which sucks the moisture out of the leaves and excretes a sticky substance called honeydew.
This can attract black mold. The best way to treat this is to apply a systemic insecticide applied to the soil.
