January 2023 Asian Longhorned Beetle (ALB) Cooperative Eradication Program Community Update


We want to keep you informed about the Asian Longhorned Beetle (ALB) infestation in South Carolina, as supportive community relationships are essential to the success of eradicating the beetle. This update is being issued to established collaborators, communities, and stakeholders, and we invite you to share this information with anyone who may be affected by our operations.


Clemson University’s Department of Plant Industry (DPI) and the United States Department of Agriculture (USDA) are conducting tree inspection surveys within Charleston County and the surrounding area to determine the size and scope of the infestation. Davey Resource Group is contracted to carry out survey and tree removal services on behalf of the ALB Program. The map below shows the approximate regulated area boundaries and infested tree locations.

The red outline represents the current ALB quarantine and totals 76.38 square miles. Within the quarantine 6,817 infested trees have been detected, each of which is represented by a red dot.






















For property owners who will have infested trees requiring removal, they should receive official notification via certified mail from DPI and, whenever possible, will be notified by a Davey Resource Group official before tree removal work begins. Davey has removed 4,388 infested trees and 2,783 high risk trees in the quarantine zone.


Federal and South Carolina State quarantines are established for Charleston County and a small portion of Dorchester County. The state quarantine legislation was enacted with publication in the State Register on June 25, 2021. See SC ALB Regulations here and view the Electronic Code of Federal Regulations here. The ALB regulated boundary is denoted by the red outline in the attached map and is also available at

Movement of firewood, storm debris, and other tree parts is prohibited from this area to prevent the spread of Asian Longhorned beetle. Even if beetles are not seen, eggs and larvae may be present within the tree material. Help informing and educating residents about this quarantine is appreciated.

Residents and businesses operating in the quarantine area should be aware that host material should be disposed of properly inside the quarantine area. Please dispose of any woody storm debris from ALB host trees to the Bees Ferry Road Convenience Center, 1344 Bees Ferry Road, 29414 or the Hollywood Convenience Center, 5305 Highway 165, 29449. Any woody debris half an inch or more in diameter is considered regulated material and must be disposed of properly. Please contact the Program with any questions about proper handling and disposal of storm debris.

The ALB program is proactively contacting businesses operating within the quarantine for guidance in how to adhere to the quarantine requirements. To sign up for free compliance training, where you can learn about how to handle regulated articles, please contact the SC ALB Program at or 843-973-8329.


In December, the program attended four events across the state to spread awareness of ALB. These included the 79th Annual South Carolina Farm Bureau Federation Conference and SC Joint Extension Conference on December 1st – 3rd and 5th – 7th respectively. Through these conferences farmers and extension professionals learned valuable information about ALB and other invasive species in SC.

Program staff also attended the December meeting of Charleston Green Drinks where the topic of discussion was trees. This event connected the ALB program with environmentally-minded community members who hold our native trees closely. The program also attended a gift-wrapping event held by the Charleston Hispanic Association. Together, with other volunteers, over 100 gifts were wrapped to be donated to local families.

On January 26th and 27th the program will be attending the SC Green Conference & Trade Show which attracts landscape professionals from across the state.

Looking ahead to February, the program will be attending the Southeastern Wildlife Expo from February 17th – 19th in downtown Charleston. This event is the largest of its kind in the country, with an estimated 40,000 attendees from across the nation

It is important to know the beetle is not harmful to people or pets. DPI and USDA tree inspectors will notify residents of survey activities on private properties before they conduct surveys whenever possible. Tree inspectors are dressed in Clemson, USDA, or Davey Resource Group uniforms and will provide identification if asked. We are asking residents to look for the beetle and to examine their trees for any damage that may be caused by the beetle. Residents can report the beetle or tree damage through the reporting tool at, by emailing, or by calling the SC ALB Program Office at 843-973-8329.
