What are Japanese beetles?
Japanese beetles are invasive insects that feed on the leaves, flowers, and fruit of more than 300 different plant species. They are easy to identify by their metallic green bodies and copper-colored wing covers. Adult beetles typically emerge in late June and remain active throughout much of the summer.
How do I know if I have Japanese beetles?
The most common sign is leaves that look like they’ve been eaten away between the veins, giving them a thin, lace-like appearance. You may also notice clusters of beetles feeding together on leaves and flowers. As beetles release pheromones that attract more beetles, small infestations can quickly grow into larger ones.
Are Japanese beetles harmful to my trees?
Japanese beetles can cause significant cosmetic damage to susceptible trees and shrubs. While healthy, established plants can often tolerate some feeding, repeated defoliation can stress plants and reduce their vigor over time. Some plants and trees are more attractive to Japanese beetles than others, making them particularly vulnerable to damage.
Should I treat for Japanese beetles?
Treatment decisions depend on several factors, including the species affected, the extent of the damage, and your long-term landscape goals. Some properties may benefit from preventive measures, while others may only require monitoring. The best approach is one that is tailored to your specific landscape.
