What angle do carpenter bees prefer to excavate wood?

Carpenter bees are known for their distinctive nesting behavior, specifically their preference for excavating wood at a right angle. This excavation occurs in the form of tunnels where they create chambers for laying eggs and storing food for their larvae. The choice of a 90-degree angle is particularly advantageous for them, as it allows for more straightforward, efficient tunneling into the wood.

Understanding the preferences of carpenter bees helps in managing their impact on wooden structures, since they can cause significant damage if left unchecked. An angle of 90 degrees is optimal for their nesting purpose, facilitating a straight path into the wood grain that is necessary for their life cycle. This knowledge is essential for those examining pest management or ecological control aspects in construction and wood preservation.
