Pine beetle experts say the latest cold snap will help — but they doubt it will be enough to wipe out the pest that has already chewed through hundreds of thousands of hectares of B-C wood. Forestry consultant Tom Lacey says cold weather, especially early in the winter, is one of the most effective ways of wiping out the voracious bug. However, he says the current deep freeze may be too little, too late to have a major impact. Mr. Lacey says he would be disappointed if Mother Nature let humans beat the beetle so easily.
