Washington state agencies are asking for your help to check your trees for signs and symptoms of invasive insects. Damaging invasive insect species, such as spotted lanternfly, longhorned beetles, and emerald ash borer, are emerging in their adult form. ate summer is often the peak time for these invasive insects to emerge from trees in their adult stage. If you see or suspect you see an invasive insect, report a sighting.

On September 12, USDA’s Animal and Plant Health Inspection Service (APHIS) and its partners declared Monroe Township in Clermont County, Ohio, free of Asian longhorned beetle (ALB). This news came just months after APHIS declared Stonelick Township free of the beetle in March. ALB was first discovered in Monroe Township in August 2011. We think people unknowingly moved the beetle in firewood from Tate Township before anyone knew about the infestation there. Before long, adult beetles emerged and started infesting trees in Monroe. To stop this pest in its tracks, APHIS and state officials had to remove 1,186 trees in Monroe. They protected 4,614 other trees by injecting a pesticide directly into the trunks. It took 7 years, but after inspecting over 177,000 trees, APHIS and its partners finally confirmed the beetle is no longer there.

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) in Massachusetts, New York, Ohio, and South Carolina in 2021. "Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "Complete eradication of this pest from the United States remains our goal, and our strategy this year will advance our efforts to eliminate this pest from where it is infesting trees."

In 2021, 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 area, respond to calls for assistance, conduct training sessions for compliance agreement holders, and perform outreach.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is announcing its 2025 plans for combatting Asian longhorned beetle (ALB) infestations in Massachusetts, New York, Ohio, and South Carolina. Every year, APHIS and its partners evaluate and determine the most effective options for eliminating the pest from the United States.

This year, 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.  State partners in New York and Ohio are exploring options for insecticide treatments in localized areas to protect non-infested trees from becoming infested with ALB. Program officials will monitor for the beetle’s presence and the movement of wood inside and around each infested area, conduct training sessions for compliance agreement holders, respond to calls for assistance, and perform outreach. APHIS will also continue coordinating with partners to develop new methods to eradicate the beetle. On March 14, 2025, 5.2 square miles were removed from quarantine in portions of Ohio. APHIS is planning to deregulate partial areas in Massachusetts and New York later this year.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is announcing its plans for eliminating ALB from Massachusetts, New York, Ohio, and South Carolina in 2024. 

APHIS and its partners are inspecting trees in quarantined areas in Massachusetts, New York, Ohio, and South Carolina. The program removes infested trees at no cost to property owners. And they will not use insecticide treatments on residential properties this year. They will continue to respond to calls for assistance and provide outreach.  

APHIS continues its work developing new ways to eradicate the beetle.

The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is asking the public to look for and report the Asian longhorned beetle (ALB). APHIS declares every August Tree Check Month and is asking you to look for this destructive, invasive beetle by checking trees on your property and in your community for damage. Left unchecked, the ALB can cause infested trees to die. August is an ideal time of year to look for the beetle and the damage it causes.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS), together with the New York State Department of Agriculture and Markets, is announcing that the Asian longhorned beetle (ALB) quarantine on Long Island is now smaller. New York is now closer to being ALB-free.

The U.S. Department of Agriculture (USDA) declares August as “Tree Check Month” for the Asian longhorned beetle (ALB). USDA and its partners are asking the public to check their trees for this invasive insect and the damage it causes and limit the movement of ALB-host materials, such as firewood. August is the most important time of year to look for the beetle because it is when people are most likely to see adult beetles.

As winter approaches, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is reminding the public not to move wood out of areas quarantined for the Asian longhorned beetle (ALB). It is important that people follow state and federal laws, which restrict the movement of woody material, to keep the tree-killing pest from spreading outside of quarantined areas in Massachusetts, Ohio, and New York.
