Japanese beetle is an invasive species, that has no natural predators. It is easy to recognize with it metallic green and cooper shell.
Japanese beetle damage makes your leaves look like lace. An infestation of Japanese can leaves behind skeleton plants.
Fortunately they are slow and easily trapped by shaking the affected plants over a bucket of soapy water. To be effective, shake daily. An application of nematodes in the spring and fall can help control population. However, it is recommended to do a second application in the spring.
