Cold snap in BC will not kill the Pine Beetle infestation

"It's too little, too late," said Lindgren, an entomologist at the university.
Whatever pine was killed in the last season in the Prince George area, the beetle population coming out will be small and have little impact, he said.
The cold snap could possibly have some effect north of Mackenzie, but the beetle larvae, which grow under the bark of lodgepole pine trees, have already produced their natural anti-freeze at this time of the year making them less susceptible to the cold, noted Lindgren.
