Gardeners Be On Alert For The Box Tree Moth

ESSEX, CHESTER, DEEP RIVER, CT —According to the U.S. Department of Agriculture website, the USDA's Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of box tree moth in the continental United States, and has implemented an emergency response to find and eradicate this pest. This invasive pest can significantly damage and potentially kill boxwood (Buxus species) plants if left unchecked. The insect is native to East Asia and has become a serious invasive pest. The caterpillars feed mostly on boxwood and heavy infestations can defoliate host plants. Once the leaves are gone, larvae consume the bark, leading to girdling and plant death.

Here’s how you can help prevent the box tree moth from spreading. Please allow State or Federal agricultural officials to inspect your boxwood trees and place an insect trap if they visit your home. If you bought a boxwood plant within the last few months, please inspect it for signs of box tree moth and report any findings to your local USDA office or State agriculture department.
