Asian Long-Horned Beetle

Last month PPQ's Asian Longhorned Beetle (ALB) Eradication Program in Ohio celebrated another victory—the ALB quarantine is officially 7.5 square miles smaller! This invasive beetle from Asia is a destructive wood-boring pest that feeds on maple and other hardwoods, eventually killing them. After completing their final round of tree inspection surveys, the ALB staff reported no sign of the beetle in a portion of East Fork State Park in Clermont County, Ohio.

"Inspecting ALB host trees is painstaking work, and the staff meticulously survey for the pest," said ALB National Policy Manager Kathryn Bronsky. "It’s been three years since the last time we've lifted ALB quarantine restrictions in Ohio, and this is the first removal of the initial area placed under quarantine. That makes this success especially gratifying."

The U.S. Department of Agriculture;s Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) infestations in Massachusetts, New York, Ohio, and South Carolina in 2022. Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication and eliminate the pest from the United States.

In 2022, the ALB program will focus on inspecting trees in quarantined areas in Massachusetts, New York, Ohio, and South Carolina, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. Program officials will monitor for the beetle’s presence inside and around each infested area, respond to calls for assistance, conduct training sessions for compliance agreement holders, and perform outreach.

Effective immediately, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS), together with South Carolina Clemson University's Department of Plant Industry (DPI), is adding portions of Charleston and Dorchester Counties to the quarantine area for the Asian longhorned beetle (ALB) in South Carolina. This action is being taken in response to the detection of two infested trees found earlier this year just outside of the current quarantine area.

If you live in the quarantine area, please help by allowing officials access to your property to inspect and remove trees. If you live in Charleston County, Dorchester County, or nearby counties, please look for ALB and examine your trees for any damage that may be caused by the beetle, such as dime-sized exit holes in tree trunks and branches. Please take pictures and, if possible, capture suspicious insects in a durable container and freeze them, which helps to preserve the insects for identification. ALB is not harmful to people or pets. Report the insect or tree damage by calling the ALB hotline at 1-866-702-9938 or submitting a report online at www.AsianLonghornedBeetle.com.

August is the height of summer, and it is also the best time to spot the Asian longhorned beetle (ALB) as it starts to emerge from trees. Because the ALB is particularly active this time of year, it can be easier to spot it or the signs of the beetle. Take a 10-minute walk around your yard or neighborhood and inspect your trees. If you see any signs, report ALB.
