Japanese Beetle Discovery Prompts Quarantine and Eradication Efforts

The Utah Division of Plant Industry is announcing the immediate activation of a Japanese Beetle (JB) eradication program following the discovery of the insect in a small area in Orem, Utah. Japanese Beetles are harmless to humans, but are destructive to lawns, fruit trees, plants and various agricultural crops.

"This is a very small infestation," said Plant Industry Director, Clair Allen. "We are asking the public to be aware of this invasive pest and voluntarily help with the control and eradication," he added.

Utah Department of Agriculture and Food inspectors have collected more than 400 beetles in several traps located in a two square mile area in Orem. The area of concern is located within the following boundaries: 800 North on the north, I-15 on the west, 400 South on the south, and State Street on the east.

The presence of JB means a threat to lawns, fruit trees, ornamental trees, shrubs, vines, and home gardens. Adult beetles feed on the foliage of the plants and many species of fruit trees. Adults leave behind skeletonized leaves and large, irregular holes in leaves. The grubs develop in the soil, feeding on the roots of various plants and grasses and often destroying turf in lawns, parks, golf courses, and pastures.

Homeowners in the area are encouraged to protect their lawns and gardens by applying an approved insecticide. For information on how to treat for the presence of Japanese Beetle, and a list of products and cautions, visit the UDAF Japanese Beetle Info page. Users are advised to read and follow label directions exactly!

Questions regarding identifying suspect beetles can be directed to the State Entomologist at: 801-538-7123 or 801-538-7184.

The presence of JB in Utah may result in an agricultural quarantine placed on Utah nursery products exported to other states. The quarantine will require agricultural producers to treat their products prior to shipping. Some states may refuse to accept certain agricultural products. The quarantine should not affect Utah fruit exports.
