Should You Treat or Remove an Ash Tree with Emerald Ash Borer? 🌳🪲

Emerald ash borer has killed hundreds of millions of ash trees across North America, and now it's arrived in Portland. When the city confirmed the invasive pest in fall 2025, many homeowners realized they could no longer ignore the threat to their ash trees and had to decide whether to treat them or remove them. Both options have real costs and trade-offs depending on your tree's health and your property's needs.

Unlike Eastern states, where emerald ash borer arrived a decade ago and most ash trees were already heavily infested or dead before homeowners could act, Portland homeowners in 2026 still have time to decide. Understanding when treatment is worthwhile—and when removal is the better investment—can help you make that decision with confidence.
