The Texas A&M Forest Service, after operating an extensive monitoring network since 2012, has confirmed that the emerald ash borer is present in Harrison County, Texas. This insect kills ash trees, be they healthy or stressed trees, and we encourage citizens to report findings of beetles that look like emerald ash borer. This means any shiny green, elongated beetle that looks like what is pictured below. This devastating pest can be slowed or contained, but it essential to know where it is. The Texas A&M Forest Service has some very good information on emerald ash borer.
