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.

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.
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.
