The Asian Longhorned Beetle (ALB), an invasive insect that kills 12 types of hardwood trees in North America, is currently in four states: Massachusetts, New York, Ohio, and South Carolina. If you work in a quarantine area, you must follow state and federal laws that restrict the movement of woody material and untreated firewood.
Federal and State officials work closely with the U.S. Department of Agriculture (USDA) to eradicate ALB using a combined approach including imposing quarantines, conducting tree inspections, removing infested trees (and sometimes high-risk host trees), using systemic insecticides when appropriate, researching best practices and new eradication methods, and involving and informing residents. Eradication efforts have eliminated infestations in Illinois and New Jersey.
The following provides information about current infestations from USDA APHIS.

All landscapers or landscape businesses performing work in the regulated area are required to comply with certain regulations. Companies doing pruning or removals, or in any way handling wood from ALB host trees within the regulated area must have a valid compliance agreement. Free compliance training is available and may be obtained by attending a 45 minute training session. Please be advised that Regulatory Officers conduct surveillance within the regulated area to enforce the quarantine, and fines may be assessed if businesses do not comply with Federal and State regulations. Training is held the second Wednesday of each month at 5:00 p.m. and the second Thursday of each month at 8:30 a.m. To register for an ALB compliance training in Massachusetts, please call (508) 852-8110 or email ALBWorcester@aphis.usda.gov.

Regulated material may not be removed from quarantine areas unless accompanied by a Limited Permit or Certificate authorizing such movement. Anyone handling ALB regulated material who wishes to obtain an AGM Compliance Agreement, enabling the movement of wood for purposes of disposal, may do so by contacting AGM. Free compliance trainings are offered by the New York State Department of Agriculture and Markets and are available for any businesses or individuals engaged in activities requiring the proper handling, movement, and disposal of regulated articles that are harvested within the ALB regulated areas. For more information about ALB compliance training in New York, call 631-288-1751.
* Brooklyn and Queens were eradicated in 2019, resulting in a reduction of the regulated area by 58 sq. miles. A new infestation detected in the Amityville area in 2013 resulted in an increase of the regulated area by 28 sq. miles. Manhattan (New York County) and Staten Island (Richmond County) were eradicated in 2013, resulting in a reduction of the regulated area by 26 sq. miles. Islip (Suffolk County) was eradicated in 2011, resulting in a reduction of the regulated area by 7 sq. miles.
Ongoing Research
USDA laboratories conduct research to learn more about the beetle. This information guides the approach used to fight infestations. Field studies, trials, and laboratory research over the years have been vital in developing the protocols used today to fight the beetle.
Current research includes regulatory treatments for wood and nursery stock, chip size and grinding techniques to deregulate host materials, traps to lure adult beetles, and the use of dogs to detect the insect’s presence. USDA is also studying how the insect spreads on its own and its host tree preference and range and conducting DNA analysis and various behavioral experiments.
