A quarantine for box tree moth (Cydalima perspectalis) was implemented on April 10, 2023, to limit the spread of this destructive and invasive pest of boxwood. The
infestation in Michigan is only the second known infestation of box tree moth in the United States, the first was found in New York in 2021.
The quarantine restricts any movement of whole plants, plant parts, and nursery stock of the genus Buxus, including all living and dead material, from movement within or outside of the quarantined zone. The quarantine zone includes the entire counties of Lenawee and Washtenaw, the county of Monroe west of US-23 and north of River Raisin, and the county of Jackson that is south of I-94 and east of US-127.
Buxus articles may be moved within the quarantine area only under a compliance agreement between the seller and the Michigan Department of Agriculture and Rural Development (MDARD). It is the responsibility of the seller to enter into a compliance agreement with MDARD if they wish to move Buxus articles within the quarantine area
