Wood borers are insects that primarily feed on wood, causing damage to trees and wooden structures. They lay their eggs in or on wood, and when the larvae hatch, they burrow into the material, creating tunnels. Common types of wood borers include beetles and wasps, which can significantly weaken the integrity of the wood over time. These pests are often found in both living trees and dead wood. The damage they cause can lead to costly repairs in homes and furniture. Effective control methods include proper wood treatment and regular inspections to identify infestations early.
