Protecting Ash Trees With Insecticide Treatments

If you don’t want to lose your ash tree to emerald ash borer, you have the option to protect it with an emerald ash borer treatment plan. It is recommended that you consider protecting large, healthy, well-placed ash trees that are within 30 miles of a confirmed ash borer infestation.

ArborThrive can evaluate the ash trees on your property and recommend which trees should be considered for treatment and which trees may not be good investments. Not always does it make sense to treat every ash tree on the property due to condition, location, size, or cost. We can help you make an educated assessment and discuss your options.

Treatments On Infested Trees

It is best to start using insecticides when ash trees are still healthy, but proper insecticide treatments can stop the borer in trees already infested. Infested trees showing less than 40-50% canopy thinning or dieback may be treated with an insecticide to stop additional damage. Ash trees already infested when treatments are started can continue to decline the first year after treatment and will begin improving in year two after the tree has time to recover.
