Small holes and reddish boring dust on a Douglas fir usually mean bark beetles are active, and Snohomish County is starting to see more of them as summer-stressed trees head into fall.
Beetles target trees already weakened by drought, root damage, or overcrowding, so one affected tree is often a warning sign for others nearby.
Arbor Vet inspects conifers for early signs of infestation and, when beetles are confirmed, removes the affected tree quickly to protect the rest of the stand from spreading damage.
Noticed anything unusual on a conifer at your property? A quick inspection can confirm what's going on before it spreads.
