Proactive management efforts to minimize Emerald Ash Borer damage is indeed recommended. Proactive measures include monitoring neighborhood ash trees (Fraxinus spp.) for signs of decline or infestation; making sure your yard trees are healthy and vigorous (proper watering and soil nutrient regimen); monitoring distribution and movement of hardwood firewood; and educating yourself about this menacing beetle (lifecycle, movement, quarantines, etc.).
Please review the following document for insecticidal treatments for home/yard trees: http://www.mortonarb.org/plantinfo/plantclinic/EABInsecticidalManagement.pdf However, according to one of our entomologists here on campus, Dr. Phil Nixon, insecticidal treatments are not only expensive, but they also will kill non-target, beneficial insects.
The biggest burden facing municipalities is the overwhelming cost of monitoring and preventative measures. Unfortunately, I don't have a good answer as to whether the city/county should remove all ash trees on public property. Regrettably, I fear we may be beyond that point.
