The temps have no meaning to EAB. It is a nasty little bug that has a strong will to survive. I'm a landscaper/ nurseryman and since they discovered the bore in my area just this early spring I have had to do some quick and intensive study on this pest. The local municipality that I live close to is taking the same cut and run stance. After some meetings and talking to the head money launderers of the city it all boils down to a funding issue. It is cheaper to cut the trees down and be done with it than to try to treat them with a systemic to kill the EAB. That's all fine and dandy since I will sell and plant more trees but the head arborist for our town is pileing all the wood in a brush dump which is open for anyone to go cut fire wood from. From his own mouth he said that they are requesting that no one take the infected wood outside of the county. I know for certain that much of that wood has gone as much as 40 miles away. Basically what has happened is that Iowa has gone to a state wide ban on hauling wood OUT of state but you can transport it anywhere within the state since they think it is a done deal.
