Answered for Shelbyville, Shelby County.
Confirmed in Indiana and spreading, though not yet the everyday problem it is further east. Worth reporting a sighting to the state rather than just treating it. In Shelbyville, shelbyville is the only town of its size around here with real canopy data coming: the Planning Department hired Davey Resource Group under an Indiana DNR grant to inventory every tree on city property and in the public rights-of-way from April through Memorial Day 2025, recording species, size and health, flagging invasives, and marking dead or hazardous trees and stumps for removal. Age tracks the housing rings — full-size canopy over the 1853-1939 Westside and the 1950s additions, and by inference much younger stock on recently annexed ground north of the city — with ash functionally absent after emerald ash borer reached all 92 Indiana counties by 2017. Damages rather than kills most trees, but the honeydew and mould make a yard unusable.

Grey egg masses that look like smeared mud, sticky honeydew and black sooty mould underneath the tree.
Damages rather than kills most trees, but the honeydew and mould make a yard unusable.
Scrape egg masses in winter; treat nymphs in spring.
