Think our recent cold snaps might halt the Emerald Ash borer in its tracks? Not likely, according to the United States Forest Service. Even though the polar vortexes are creating havoc on our landscapes, one place that’s still cozy is deep inside the wood of trees.
For the cold to smack the Green Menace down, temperatures have to dip to at least minus 20-degrees F inside the wood, and even colder temperatures are needed to kill higher numbers of larvae. Boulder hasn’t seen those types of low temps, so don’t count on Mother Nature giving the cold shoulder to the emerald pest this winter.
