Effective immediately, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the Michigan Department of Agriculture and Rural Development (MDARD), is expanding the quarantine for the box tree moth (BTM, Cydalima perspectalis) to include all of Clinton, Eaton, Ingham, Jackson, Livingston, Monroe, Oakland, and Wayne Counties in Michigan.

Box tree moth will destroy most boxwood shrubs in the country if it becomes established. Growers and landscapers can help by protecting newly planted boxwoods.

In May of this year, USDA confirmed the presence of box tree moths in the U.S. The pests likely hitchhiked here via infested plant material imported from an Ontario, Canada nursery. APHIS has initiated an emergency response including a federal order halting host material from crossing the border pending risk analysis. Here is a set of resources supporting identification of this pest to help protect America's boxwoods.

A Federal Order is a legal document issued in response to an emergency when the Administrator of APHIS considers it necessary to take regulatory action to protect agriculture or prevent the entry and establishment into the United States of a pest or disease. Federal Orders are effective immediately and contain the specific regulatory requirements.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of box tree moth (BTM) (Cydalima perspectalis) at two residences in Clinton located in Lenawee County. Although not a threat to Michigan’s natural resources, extensive feeding from box tree moth can lead to significant defoliation and death of ornamental boxwood.  In May 2021, potentially infested boxwood plants were shipped to retail locations in several states including six in Michigan. The pest was then identified in three of the six Michigan facilities. It is not known whether the box tree moth populations detected in Clinton are linked or if the pest entered the state through another pathway.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of the box tree moth (BTM) near the border of Hamilton and Clermont counties.

A local resident submitted a photo of the insect to the USDA earlier this month, resulting in trapping in the area. Two specimens captured were identified as the BTM.
