Emerald ash borer #797454

Asked June 23, 2022, 2:09 PM EDT

Do we need to continue treating our ash tree for the emerald ash borer? We've had it treated (injection) for around 12-13 years now. The ash tree is around 40 years old. It is a mainstay in our backyard that faces the north and is a great shade tree so we don't want to lose it.

Expert Response
"Although emerald ash borer will never be eradicated you only need to treat trees aggressively until all the untreated trees nearby have been killed. After that time you should monitor your trees for fresh signs of injury. Typically this will be fresh woodpecker holes in the upper canopy or a new canopy thinning." quoted from Purdue EAB publication
