Burma teak, known for its exceptional quality and durability, has a unique characteristic called the “bee hole phenomenon.” This phenomenon is primarily caused by the beehole borer, a pest that significantly impacts the quality of teak timber. Let’s delve into what makes this phenomenon so unique and why it’s important for those working with teak wood.
What is the Bee Hole Phenomenon?
The bee hole phenomenon refers to the long tunnels or “bee holes” created by the larvae of the bee hole borer (Xyleutes ceramica) inside the trunk of living teak trees. These tunnels can be several inches long and significantly affect the wood’s structural integrity and aesthetic value.
The Interesting fact about Bee Hole
When you see a log from its exterior which is impacted by a bee hole borer, in most of the cases you will not at all be able to assess the damage it has created inside the log. What you may end up seeing externally are a couple of entry points(holes of around 1 inch dia) of these bee holes.
But, they would have travelled meters after meters inside the living tree at their free will and created long holes as a trail.

Impact on Teak Quality
The presence of bee holes in teak wood can greatly reduce its market value. The tunnels disrupt the uniformity of the wood grain, making it less appealing for high-quality furniture and other fine woodworking projects. Additionally, the damaged wood is more prone to cracking and splitting, which can compromise its durability.
Lifecycle of the Beehole Borer
The lifecycle of the beehole borer begins with the adult moth laying eggs on the bark of teak trees. Once the eggs hatch, the larvae bore into the wood, creating the characteristic bee holes. The larvae feed on the wood’s inner layers, causing extensive damage before they eventually pupate and emerge as adult moths to continue the cycle.
Conclusion
Although the bee hole phenomenon is not exclusive to Burma teak and can be found in other tropical forests and hardwoods, it presents a unique challenge when it comes to Burma teak. This is due to the fact that Burma teak is one of the most expensive timbers worldwide, and the presence of bee holes can significantly reduce the commercial value of the teak log.
