Emerald Ash Borer

Ash BorerEAB Quarantine Extended to All of Connecticut

The quarantine for the invasive, non-native emerald ash borer (EAB) was extended to include all eight Connecticut counties effective December 5, 2014. This was in response to the detection of EAB in Middlesex and New London Counties. EAB is already established in numerous towns in New Haven, Fairfield, Hartford, and Litchfield Counties. The movement of ash (ash logs, ash materials, ash nursery stock, and other regulated articles) within and between the eight counties of Connecticut are no longer subject to state or federal quarantine. However, out-ofstate transport of ash and the transport of firewood of all tree species, including ash, within Connecticut continue to be regulated. Connecticut was added to the federal EAB quarantine around the same date. More information about the emerald ash borer and related quarantines can be found on these websites: DEEP, Connecticut Agricultural Experiment Station.

Emerald ash borer insecticide treatment considerations. Several insecticide products are available to homeowners for control of emerald ash borer (EAB). Since the presence and infestation level of EAB is quite difficult to determine at early stages of an infestation, insecticide treatments may be merited to mitigate damage by EAB. However, not all ash trees should be treated as some may be too extensively compromised or in poor condition to receive treatment. Tree location, value, and health, as well as the cost of treatment are all factors to consider. Due to the expense of yearly insecticide treatments, one should consider the value of a particular ash tree in relation to insecticide treatment costs before making any treatments. In addition, consider the health of each tree before treating. Research suggests that insecticide treatments are significantly more effective on EAB-infested ash trees with less than 50% canopy thinning. Insecticide treatments are not suggested for trees with greater than 50% canopy thinning. Trees with greater than 50% canopy thinning should be removed and destroyed.
