Emerald Ash Borer

This wonderful creature, Emerald Ash Borer (or referred to as EAB), has now been found up in the Western NY area. This finding has created a lot of panic and concern, some of it justifiably so.

Understanding what EAB does and how it moves is crucial. The insect is originally from Asia and came into the US through Ship Deliveries in the Detroit area. It has moved while 'sitting' or 'hiding' in wood material, namely Ash. It has moved through out the USA through movement of Ash Trees and Wood. Timber and Firewood are currently the main carriers as many growers no longer grow or ship Ash Trees to nurseries. The beetle can only fly 3km a year naturally, but through timber and firewood, it can go long distances quickly.

Western NY is widely populated with Ash trees. There are currently no natural predators, but it is being studied. There are some preventive treatments that have been fairly effective. Sometimes these measures can be applied by the homeowner, but for big trees you need to get a professional tree service, with knowledge of EAB, involved.

We have an actual sample of damage to a tree (in Michigan) and the actual insect, both larvae and adult form, on display at Van Putte Gardens. Come see the display and we can answer your questions.
