Michigan Urges Residents to Protect Trees from Invasive Beetle

By Andi Anderson

Michigan officials are asking residents to play an active role in protecting trees from the destructive Asian Longhorned Beetle (ALB), an invasive insect that poses a serious threat to hardwood forests and urban landscapes. The awareness effort is part of the annual Tree Check Month campaign, which encourages people to inspect trees and report signs of infestation.

The initiative is being led by the Michigan Invasive Species Program in partnership with the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS). August has been designated as Tree Check Month because it is one of the best times of the year to spot the beetle and identify the damage it causes.

The Asian Longhorned Beetle is a non-native wood-boring insect that attacks a variety of hardwood tree species. It is especially known for damaging trees such as maple and elm. The beetle can be identified by its shiny black body covered with white spots and its large size, reaching about one and a half inches in length.

According to experts, the insect is considered highly destructive because it tunnels deep into trees, weakening their structure over time. Once a tree becomes heavily infested, recovery is unlikely. Infected trees typically decline and eventually die, creating potential safety hazards for people and property. Dead or weakened branches may fall unexpectedly, and severely damaged trees can become unstable.

Michigan officials are encouraging homeowners, farmers, landowners, and community members to regularly inspect trees on their property and in public areas. Early detection is considered one of the most effective ways to prevent the spread of the beetle and protect valuable tree populations.

Protecting trees is important not only for environmental health but also for local communities, wildlife habitats, and property values. Healthy trees provide shade, improve air quality, reduce soil erosion, and contribute to the overall beauty of neighborhoods and rural landscapes.

Residents who notice unusual damage, signs of insect activity, or symptoms associated with the Asian Longhorned Beetle are urged to report their findings immediately. Prompt reporting can help specialists investigate potential infestations and take action before the pest spreads further.

Anyone who believes they have found evidence of Asian Longhorned Beetle damage can contact the ALB Hotline at 866-702-9938. Public participation remains a critical part of efforts to monitor and manage invasive species, helping safeguard Michigan’s trees and forests for future generations.
