How to Identify Longhorn Beetles



Longhorn beetles range in size form 1/8″ to 6″ long. They are easily recognized by their long antennae that can extend the entire length of their body. Adult longhorn beetles are usually black with orange or yellow patterns.


Longhorn beetles typically enter wood structures during their larvae stage. They feed on trees, untreated lumber, wood siding, and other wood inside the home. These pests are often not detectible until they bore a small hole to exit a wooden structure on their way to reproduce.


Longhorn beetle infestations are easily confused with termites because of the damage they inflict on wood. The boring beetles can feed on wood for years, weakening the structural integrity of the wood.


Similar to other wood eating pests, longhorn beetles tend to avoid wood treated with paint or varnish. Untreated wood should be checked for exit holes and females laying eggs on the exterior of wood materials. Longhorn beetle eggs not removed will cause a new infestation in the wooden structure.


A professional treatment is the best way to identify, reduce, and help prevent a large infestation of longhorn beetles. Cook’s Pest Control offers professional treatment for the reduction of longhorn beetles. Our technicians are thoroughly trained to address your pest problems.
