Boring insects are pests that tunnel into wood, causing damage to trees and wooden structures. Common examples include the wood-boring beetle and termite. These insects lay their eggs in wood, and when the larvae hatch, they burrow through the material, weakening it over time. The damage caused by boring insects can lead to significant structural issues in buildings and can harm the health of trees. Effective management often involves identifying the type of insect and using treatments like insecticides or preventive measures such as proper wood treatment and maintenance.
