ALB Update - Amy Stone

August 25, 2023

USDA works closely with Federal and State officials to eradicate Asian Longhorned Beetle (ALB) using a combined approach that includes imposing quarantines, conducting tree inspections, removing infested trees and sometimes high-risk host trees, using a systemic insecticide when appropriate, researching best practices and new eradication methods, and involving and informing residents. The following provides information about current infestations. 


Tree Check Month

August is almost over but it’s not too late to help the eradication programs by checking your trees for the Asian longhorned beetle and the tree damage it causes. Watch the video on how to spot the signs and report anything suspicious here.


USDA Under Secretary Jenny Moffitt recently visited the program in Ohio where APHIS and the Ohio Department of Agriculture are working to eradicate the insect.

ALB in the United States

ALB is in 4 states: Massachusetts, New York, Ohio, and South Carolina. Eradication efforts eliminated infestations in Illinois and New Jersey. If you live in a quarantine area, please keep this tree-killing pest from spreading. Follow state and federal laws, that restrict the movement of woody material and untreated firewood.

* 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.


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.

If you live in a quarantine area, you can help by allowing program officials access to your property to perform tree surveys and remove infested and, in some cases, high-risk host trees. Hire companies that have compliance agreements with the eradication program for working on host trees. And never move wood out of regulated areas, because it can spread the beetle and other tree pests and diseases.

Report ALB

If you think you’ve found ALB or an infested tree, record the area, capture the insect, and take digital pictures. Then contact the eradication program operating in your state, or call the ALB hotline at 866-702-9938, or report online.

Asian longhorned beetle eradication programs are cooperative programs. USDA’s Animal and Plant Health Inspection Service works with the U.S. Forest Service, the Agricultural Research Service, and partnering organizations in each state. In South Carolina, the eradication program includes Clemson University’s Department of Plant Industry and the College of Charleston. In Ohio, the eradication program includes the Ohio Department of Agriculture, Ohio Department of Natural Resources, Ohio State University Extension and Clermont County. In Massachusetts, the eradication program includes the Massachusetts Department of Conservation and Recreation and the Massachusetts Department of Agricultural Resources. In New York, the eradication program includes the New York State Department of Agriculture and Markets.
