Emerald Ash Borer
Posted on Nov 13th, 2014
The emerald ash borer is an invasive, Asian parasite that attacks both red and white Ash trees. The infestation began in northern America over five years ago and progressively made its way southward. Its estimated that over 25 million Ash trees have died as a result of this infestation.
From Lexington to Louisville and north to Cincinnati, ash trees are being wiped out from rural landscapes, parks, leafy subdivisions and urban corridors. Unfortunately, this problem has hit home here in Heritage Hill as the majority of trees along our streets are Ash trees. All of the Ash trees in the subdivision show signs of the pests ("D" shaped bore holes, thinning of the upper canopy, and larvae tunnels).
June Pearce, representing the board of directors, met with an arborist this past spring and determined that some trees were already doomed. However, it is not too late to save most of our remaining trees. Treatment options are available and once started require a long term commitment. It is estimated the cost of treatment to be about $200 every year or two, per tree. Additional information regarding your treatment options is available HERE.
Emerald ash borer
• Discovered in North America in 2002, after likely hitching a ride on cargo ships from Asia.
• During larval stage, borers feed under the bark of ash trees, destroying tissues that move water and nutrients.
• Tree death is within one to three years.
• Borer adults mate after emerging in the spring through D-shaped exit holes.
• Each female can lay up 90 eggs during their two- to three-week lifespan; eggs hatch in seven to 10 days.
• Healthy and vigorously growing trees with more than half their leaves may be saved with chemical treatment.
• Unhealthy trees with more than half of their leaves missing probably cannot be saved.
• Consult at least two certified arborists before making a decision.
• Expect to treat ash trees indefinitely.
• Buy firewood where you burn it. Moving infested ash spreads the borers.
