What is Emerald Ash Borer (EAB)?

Emerald Ash Borer, known as EAB, is an invasive insect that attacks ash trees. This wood-boring insect feeds under the bark of ash destroying the tree's vascular system, resulting in the decline of your tree's health and death within a few years.

Native to China, the Emerald Ash Borer was first discovered around 2002 in the Detroit area. It is believed to have been brought into the US from infested wooden cargo pallets.1 Since that time, the Emerald Ash Borer has moved into Canada through Windsor and has been detected across southern Ontario and as far East as the Montreal area.2

Is my ash tree at risk from Emerald Ash Borer?

The Emerald Ash Borer is an extremely mobile insect. A strong flyer, it is known to hitch a ride on vehicles or in ash fire wood. Given its mobility and aggressive feeding, experts agree that all ash trees in Ontario are at serious risk of Emerald Ash Borer infestation and elimination within the next 10 years.3,4

What can be done to control the Emerald Ash Borer or protect my tree?

In Canada, a natural insect control product has been developed that is showing success in protecting ash trees from the Emerald Ash Borer and controlling early stages of infestation. This product is produced from extracts of Neem tree seeds, which have been used for centuries to control insects.

This acts as a systemic control, as it is injected into the trunk area of the ash tree using contained capsules. The product is taken in by the tree's conductive tissues and moved upwards throughout the tree with water and nutrients. This application must be repeated every two years.5 It is an organic product which is exempt from Ontario's pesticide ban and is listed by the Organic Materials Review Institute (OMRI). This product cannot be purchased in stores and is only available by licensed professionals6, such as GreenLawn Canada.

Should I get my ash tree treated for Emerald Ash Borer?

An Emerald Ash Borer infestation will almost certainly kill your ash tree unless it is treated properly by a professional. However, decisions to remove or protect your ash tree may depend on several factors.

The first consideration is the relative health of the tree. The tree must be in good health for the treatment to be effective. If the tree is under stress from infestation, disease or other health problems, the tree will not effectively absorb the treatment and transport the product through its system.

Given the spread of Emerald Ash Borer, it is widely accepted that homeowners who have ash trees will eventually have to pay for removal or treatment of an Emerald Ash Borer infection. Either way, it will cost you. Your decision to either save your tree or remove it must take into account the value a majestic ash has to you, your home and the overall environment.

How much does Emerald Ash Borer control cost?

Treatment to control Emerald Ash Borer infestations depends on the size of the tree. A GreenLawn Canada Tree Specialist can measure and determine treatment pricing. The cost of treating an ash tree over the course of an Emerald Ash Borer outbreak can be less than the cost of removing, disposing and replacing it. Removal and replacement of an established ash tree on a home or commercial landscape can require 30 years before the replacement tree reaches the same size and contribution to the environment and your landscape value. This amount of time represents considerable loss to your home and the environment.
