A routine annual problem on Indiana evergreen hedging. In Speedway, no public street-tree inventory has been published for Speedway, so species counts are UNVERIFIED. Because the residential core finished building out by the mid-1950s and has barely been rebuilt since, much of the yard canopy is likely of comparable age and large enough to close over narrow streets and 40-to-50-foot lots — an inference from build-out dates, not a measured finding. The exception is Main Street, where a town streetscape reconstruction installed all-new landscaping, so those trees are recent. An evergreen stripped by bagworms usually does not regrow those needles — arborvitae and spruce don't refoliate bare wood.
Speedway's canopy and what's at risk
No public street-tree inventory has been published for Speedway, so species counts are UNVERIFIED. Because the residential core finished building out by the mid-1950s and has barely been rebuilt since, much of the yard canopy is likely of comparable age and large enough to close over narrow streets and 40-to-50-foot lots — an inference from build-out dates, not a measured finding. The exception is Main Street, where a town streetscape reconstruction installed all-new landscaping, so those trees are recent.
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
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.
