Bark Beetle Treatment

Bark Beetle Treatment

We offer short-term and long-term treatment to protect Washington native trees from bark beetle attacks.

Your forest is in decline and you suspect bark beetles. What is the best course of action?

Bark beetles, engravers and other wood boring pests can invade and cause damage to forests across the United States. In Washington, our Douglas-fir, hemlock, fir and pine trees are susceptible to a variety of wood boring pests. Luckily these pests can be treated and controlled.

We protect trees against bark beetle attacks across all of the Puget Sound and Western Washington. Treatment normally occurs in early spring, prior to beetle emergence.

What are the symptoms of a bark beetle attack?

Key features of Douglas-fir bark beetle attacked trees include: significant amounts of frass in bark cervices and around the base of the tree, pitch streams high on the stem, and root disease. It is important to note that Douglas-fir bark beetles generally attack larger trees >14in diameter at breast height).

How can you prevent an attack on trees or stands of trees?

We combat Douglas-fir bark beetle damage with the use of beetle pheromones to control their behaviors.  These pheromones are used by beetles naturally to communicate with each other.  We target individual pheromones to interrupt beetle aggregation on specific trees and avert attacks on high value trees.

Where We Apply Anti-Aggregation Pheromones

Prevention is key when it comes to protecting significant trees or stands of trees from a Douglas-fir Bark Beetle attack.  Pheromone treatments are successful on an individual tree basis to <1 acre to 1-500-acre scale and are appropriate for trees when Douglas-fir bark beetle-initiated tree mortality could significantly affect high value trees or resource management objectives.

Integrated Pest Management Program

Pheromone treatment methods are only one part of an Integrated Pest Management (IPM) program and are most efficient when used in conjunction with a larger management strategy. Additional IPM activities include removing or burning infested trees, thinning and promoting size class diversity of trees, and monitoring beetle activity until their activity subsides.
