With the news that emerald ash borer has been found in northeast Iowa, ISU Extension experts encourage Iowa homeowners to evaluate their ash tree and hold off on any insecticide treatments at this time.
The movement of firewood throughout Iowa and to other states poses the greatest threat to quickly spread EAB even further. Areas currently infested are under federal and state quarantines, but unknowing campers or others who transport firewood can spark an outbreak. As a result, officials are asking Iowans to not move firewood and instead buy wood where they are staying and burn it completely.
The metallic-green adult beetles are a 1/2-inch long and are active from late May to early August in Iowa. Signs of EAB infestation include 1/8-inch D-shaped exit holes in ash tree bark and serpentine tunnels packed with sawdust under the bark. Tree symptoms of an infestation include crown thinning and dieback when first noticed, epicormic sprouting as insect damage progresses, and woodpecker feeding.
