Emerald Ash Borer FAQs

What is the Emerald Ash Borer (EAB)?

The EAB beetle is a non-native invasive insect, it attacks and kills most varieties of ash trees (white and green ash). EAB is confirmed in the Town of Ajax. Adult EAB beetles lay their eggs on ash trees in the summer. When the eggs hatch into larvae, they tunnel under the tree's bark to feed. The tunnels prevent the flow of water and nutrients, causing the tree to die.

How will EAB impact the Urban Forest in Ajax?

Ash trees make up approximately 7% of the town's urban forest, on both private and public property. The Urban Forest has an inherent value and provides us with numerous benefits - helping clean the air we breathe, shading us from harmful UV rays, beautifying our town and many others. Untreated ash trees are expected to be impacted or killed by EAB over the next 10 years.

What is the Town of Ajax doing about EAB?

The Town is currently implementing its EAB Management Strategy, which aims to reduce the significant aesthetic, environmental and financial impacts of the EAB. This is being done through a combination of monitoring, treatment, ash tree removal and replacement, and public education. Private property owners are responsible for trees on their property.

What should I do if an ash tree on my property is infested?

Property owners who suspect an EAB infestation are encouraged to contact a professional arborist, certified with the International Society of Arboriculture (ISA) or the American Society of Consulting Arborists.
