Asian Longhorned Beetle Quarantine Requirements

​​The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has imposed an exterior quarantine on items that could carry Asian longhorned beetle (ALB). An exterior quarantine restricts import of regulated plant products and other items from areas infested with ALB. DATCP regulations coincide with the federal quarantine and regulations for ALB imposed by the U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS).

Areas Covered by the Quarantine​

The quarantine applies to certain counties of Ohio, Massachusetts, New York, and South Carolina. All applicable counties are identified in the Code of Federal Regulations (CFR). Areas where ALB has been found but eradicated (Illinois and New Jersey) are not covered by the quarantine.

Items Covered by the Quarantine

  • Any living life stage of ALB

  • Non-coniferous firewood

  • Nursery stock, logs, green lumber, stumps, roots and branches from these genera: Acer (maple), Aesculus (buckeye), Albizia (mimosa), Betula (birch), Celtis (hackberry), Fraxinus (ash), Platanus (sycamore), Populus (poplar), Salix (willow), Sorbus (mountain ash), and Ulmus (elm)

  • Any other item that a pest control official determines poses a risk of spreading ALB

Exceptions ​

Regulated items can be imported into Wisconsin, if accompanied by a certificate signed by a pest control official in the state or province of origin who has inspected the items and certified that the items:

  • Originate from non-infested premises and have not been exposed to ALB, or

  • Were free of ALB at the time of inspection, or

  • Have been effectively treated to destroy ALB, or

  • ​Were produced, processed, stored, handled, or used under conditions that would prevent transmission of ALB
