Answered for Cumberland, Marion County (town limits extend east and north into Hancock County) County.
A routine annual problem on Indiana evergreen hedging. In Cumberland, the biggest and oldest trees stand in Old Town along US 40, over houses on a corridor continuously settled since 1831 — that is where a crew will meet 100-plus-year specimens with structures under them on both sides. Buck Creek carries the bottomland canopy, the east-side Hancock County subdivisions date from the 1970s through the 2000s and their canopy is mid-life, and ash has been removed across central Indiana by emerald ash borer; no published street-tree inventory exists for the town. An evergreen stripped by bagworms usually does not regrow those needles — arborvitae and spruce don't refoliate bare wood.
Cumberland's canopy and what's at risk
The biggest and oldest trees stand in Old Town along US 40, over houses on a corridor continuously settled since 1831 — that is where a crew will meet 100-plus-year specimens with structures under them on both sides. Buck Creek carries the bottomland canopy, the east-side Hancock County subdivisions date from the 1970s through the 2000s and their canopy is mid-life, and ash has been removed across central Indiana by emerald ash borer; no published street-tree inventory exists for the town.
What to look for
Small spindle-shaped bags hanging from branches, made of the tree's own needles. Often mistaken for cones.
Whether the tree can be saved
An evergreen stripped by bagworms usually does not regrow those needles — arborvitae and spruce don't refoliate bare wood. Catching them early is the difference between a treatment and a replacement.
Timing in Marion County (town limits extend east and north into Hancock County) County
Spray in June when the larvae are small. After midsummer the bags are sealed and spraying does nothing — at that point picking them off by hand is the only option that works.
