Japanese beetles cause damage to ornamental, garden, and agricultural plants. They are invasive to the United States and are not found here naturally. They often find plants in nurseries, orchards, greenhouses, and field crops to feed upon. The beetles can cause serious damage to leaves, fruit, and flowers on almost 300 different plants. Japanese beetles emerge from the soil in the summer to feed on plants. Their grubs also damage lawns.
Japanese beetles are mostly found in the eastern United States. They have been found in some locations in the western United States, usually near large cities. Over $460 million dollars are spent yearly to control larval and adult Japanese beetles.

Through its county agents, the Cooperative Extension Service gives individuals access to the resources at land-grant universities across the nation. These universities are centers for research in many subjects, including entomology (the study of insects) and agriculture. Each county within the United States has an Extension office, which is staffed with agents who work closely with university-based Extension specialists to deliver answers to your questions about gardening, agriculture, and pest control. You can find the phone number for your local county extension office in the local government section (often marked with blue pages) of your telephone directory or by clicking on the map below.
