Temperatures well below zero in the Midwest in late January and early February may help stop the pest in its tracks.
Several articles point to the cold temps causing 85 to 95 percent of larvae to die. Japanese beetles and gypsy moths also may succumb to the cold weather.
Even if a high percentage die off, it still won’t stop the hundreds of thousands of EABs and other species from spreading.
An article in the Journal Sentinel estimates EAB has caused the death of tens of thousands of square miles of ash trees in Wisconsin alone.
More information on the EAB and ways to preserve ash trees will be available in the February 2019 issue of Irrigation & Green Industry magazine.
