Answered for Avon, Hendricks County.
It has already moved through Indiana and killed the overwhelming majority of untreated ash. An untreated ash here is on a clock, not at risk. In Avon, overwhelmingly young, nursery-planted stock: only 3.4% of Avon's housing predates 1960, so the typical "big tree" here is a 20-to-30-year-old subdivision planting rather than a legacy shade tree, with exceptions in the White Lick Creek bottomland and the fencerow remnants left when farm fields were platted. Ash is gone, and Avon's street tree ordinance actively steers right-of-way planting toward tall shade-producing species, reserving ornamentals for spots where space genuinely prevents a large tree. Treatable while the canopy is still mostly intact.

Thinning from the top down, D-shaped exit holes about an eighth of an inch across, sprouts low on the trunk, and pale flecking where woodpeckers have stripped bark to get at larvae.
Treatable while the canopy is still mostly intact. Once roughly a third of it is gone, treatment stops being worth the money and the tree becomes a removal — and a dead ash goes brittle unusually fast, which makes it both more dangerous and more expensive the longer it stands.
Trunk injection in spring or early summer, repeated every one to two years for the life of the tree. It is a permanent commitment, not a cure.
