During the last month I’ve been getting my fair share of questions about Japanese Beetles. This beetle is known to be the most devastating pest of urban landscape plants in the eastern United States. The Japanese beetles were first found in the United States in 1916 in New Jersey. Before, it was known only to occur in Japan where it is not considered a major pest.
The eastern United States provides a great climate, large areas for developing grubs, and hundreds of different plants for the adults to feed on. There are also no natural effective enemies to control these beetles. All these conditions make it possible for the Japanese beetle to continue to thrive.
