The movement of beetles to new areas can also be influenced by the availability of food plants and natural dispersal. While this might be a temporary occurrence, it could also indicate a broader shift due to changing environmental factors,” he said.
A earlier employee of Tim’s, that at present does yard maintenance, noticed a buyer’s timber had really been “decimated” by the beetles and referred to as Tim to ask if he had really seen the pests round up to now.
