Longhorn beetles can be harmful primarily to trees rather than humans. Their larvae bore into living trees, creating tunnels inside the wood that can severely damage or even kill the tree. For example, the Asian Longhorned Beetle (ALB) is known to attack healthy broadleaf trees, causing significant damage by hollowing them out from the inside over a period of years. This damage can lead to tree dieback and death, making these beetles a serious threat to urban and forest trees, as well as industries dependent on hardwoods.

While longhorn beetles do not pose a significant threat to humans-they rarely show aggressive behavior and are not poisonous-they can bite if mishandled, causing painful but not dangerous bites. They do not damage furniture or household items, as they prefer living or freshly cut wood rather than dried wood.
Are longhorn beetles harmful
In summary:
Harm to trees: Longhorn beetle larvae tunnel inside living trees, damaging and potentially killing them. This can lead to large-scale ecological and economic impacts, especially with invasive species like the Asian Longhorned Beetle.
Harm to humans: They are not poisonous and generally not aggressive, but can bite if provoked, causing painful bites without lasting harm.
Harm to property: They do not attack furniture or dried wood products.
Therefore, longhorn beetles are harmful mainly as tree pests rather than as a direct threat to humans or household items.
