PINE BARK BEETLE CONTROL SUMMARY ^ Pine bark beetles can be a problem for homeowners and land owners all around the world. Preventive treatment is best, as trees with existing beetle infestations are unlikely to survive. Removing as many infested trees as possible before the spring swarming starts is now critical. When a bark beetle penetrates the cambial layer, it chews out galleries, or tunneled lanes and grooves.Here the bark beetle lays eggs that hatch into larvae, which feed on the tree by gnawing out more galleries.Damage introduces fungi that can interfere with the tree’s ability to transport water. can modify the importance of bark beetle infestation drivers. Correct identification of attacking beetles is crucial. Salvage – This technique is usually feasible only when a relatively large volume of wood is available.Prompt action in salvaging large infestations is often necessary to prevent beetle expansion and to realize the best possible return from the sale of infested trees. Techniques for Bark Beetle Control. The beetle usually attacks weakened trees (e.g., drought or wildfire damage) or trees blown down by windstorms. It attacks its host in early summer. Reduce potential damage from pine bark beetles with well-timed thinnings and quick removal of wind- or fire-damaged conifers. Twenty-eight giant sequoias have died since 2014.
