Integrated Pest Management Strategies
Effective control requires a multi-pronged approach:
-
Monitoring: Regularly inspect trees, especially during spring and early summer when bugs are most active.
-
Mechanical Control: Physically remove and destroy egg masses and nymph clusters by hand (wear gloves). This can be highly effective for small-scale infestations.
-
Biological Control: Promote natural predators. Certain species of parasitic wasps (like Anastatus spp.) target stink bug eggs, and birds can help reduce nymph and adult populations.
-
Chemical Control: Use insecticides only as a last resort and with precision. Target young nymphs, which are more vulnerable. Always follow label instructions to protect beneficial insects and the environment.
