Summer increases risk of emerald ash borer exposure


CHAMPAIGN, Ill. – As the summer tourism season gets underway, The International Society of Arboriculture
cautions people about the possible spread of emerald ash borer among the urban tree canopy in cities and
forests across the U.S.
Considered the "Green Menace", experts say EAB is now in 21 states and has also been detected
in Canada. The beetle is native to Asia and strikes North American Ash trees. Scientists say those ash
trees destroyed by EAB create a damaging effect on the eco-system and can even impact homeowner property
values. Already, EAB destruction has cost municipalities, property owners, and the green industry tens
of millions of dollars.
"As people travel and make trip plans for the summer, the chances escalate for EAB movement to
unaffected areas, especially when people transport firewood," says Jim Skiera, ISA Executive
Director. "Woodlot management, planting trees that are resistant to EAB and hiring an ISA Certified
Arborist to protect trees with proper care and maintenance are all ways to prevent infestation."

To stop the spread of EAB, ISA recommends the following:
• Don’t move firewood – Obey quarantines on wood transportation if prohibited where you live. Be sure to
buy firewood near your camp site or from a firewood vendor who is certified.
• Recognize the signs of infestation – Did you know the EAB is green, skinny and about as long as a
penny? Improve your knowledge about this insect and find state hotlines to report a problem. Visit ISA’s
redesigned and updated consumer website,, for more on EAB and how to stop the
• Pre-treatment programs – There are ways to protect ash trees before they become infected with EAB.
Consult an ISA Certified Arborist to inspect ash trees on your property and suggest proactive measures
for curbing tree infestation.
