A University of Montana professor of forest entomology and pathology says this prolonged and uncomfortable deep freeze probably won't be enough to kill Mountain Pine Beetles.

The rice grain-sized beetles are a native species that mass-attack trees. U-M College of Forestry and Conservation's Dr. Diana Six says hundreds or thousands of the insects can swarm a single tree, leaving it defenseless and essentially doomed.
