Non-Chemical Management
- Avoid injury to trees, especially during spring and summer. Adult beetles are attracted to wounds.
- On elm, control of bark beetles is essential to prevent the spread of Dutch elm disease.
- Maintain plant health. Healthy plants are less susceptible to infestation. Select the proper plant for the site and provide proper cultural care.
- Remove damaged or infested limbs in spring before adult beetles emerge. Also remove dead or dying trees. Remove and destroy bark from freshly cut wood, or burn or bury wood.
