If you live near Rockville, MD – or are a property owner in Montgomery County with ash trees – you are urged to get your ash trees treated immediately for emerald ash borers. If you wait for signs of infestation – it will be too late. May and June is the time to use preventive insecticides against the Emerald Ash Borer in Maryland.
An entire block of Twin Oaks Drive in Rockville, MD and Potomac Springs neighborhood have been infected and every single native ash tree will have to be removed this Spring (City Forester, Wayne Noll, reported to the mayor and council at their March 23, 2015 meeting). Ash trees die quickly and become a falling hazard for humans.
The State of Maryland is at infestation level and not much can be done. Natural predators, like woodpeckers, help prevent the spread of the Asian EAB (Emerald Ash Borers).
People shouldn’t transport firewood or wood products made from ash which is the primary way they get to different areas. EAB is now known to be in 22 states, including Maryland. The Emerald Ash Borer was first reported in Michigan in the 1990’s.
Scientists are studying the rare native elm that doesn’t become infested for clues in their resistance.
The adult EAB eats the ash’s leaves but it’s the larvae that kills the tree with its treacherous boring. (see image below).
Contact Wood Acres Tree Specialists if you still have a healthy native elm tree for a professional consultation and insecticide treatment.
