Emerald Ash Borer in Connecticut

Updated: May 15, 2018

Connecticut is working to slow the spread of the emerald ash borer (EAB).  Slowing the arrival of the insect in new locations will give more time for cities and towns to prepare themselves. Everyone can help with "slowing the spread".  Find out what you need to know regarding EAB.

Homeowners who have ash trees on their properties are encouraged to know the signs of the emerald ash borer (EAB).  Unless the insect is known to be in the vicinity, pre-emptive removal of ash trees is not recommended.  Healthy trees provide a great many environmental benefits, including contributing to the value of a property. 

Trees infested by EAB or in the vicinity of an EAB infestation (about 15 miles) can be effectively treated with a systemic insecticide. Homeowners are encouraged to be aware of the health and condition of all of their trees.  Should there be any questions regarding the health of their trees or the presence of EAB, homeowners are encouraged to make use of services such as those provided by an arborist licensed by the State of Connecticut, such as Natural Systems Tree Removal in Southington.

Property owners who wish to cut down an ash tree, or any hardwood tree for that matter, and make use of it as firewood should be aware of the regulations regarding the movement of firewood.  In particular, property owners should know of the requirement for documentation regarding the transport of firewood.  The easiest way to meet this requirement is through a Self-Issued Firewood Transportation Certificate.

Woodland Owners in Connecticut are encouraged to be able to recognize signs of the emerald ash borer, as well as to know how to identify individual ash trees.  Overall, ash is a small but significant component of the forests within the state, but it may be a major component of any individual woodland owner's property. 

Further details regarding EAB regulations and the quarantine are available on the Connecticut Agricultural Experiment Station EAB Page.
