What type of damage does the larva of the death watch beetle cause?

The larva of the death watch beetle primarily causes extensive tunneling in wooden beams. This wood-boring insect lays its eggs in wood, and once the larvae hatch, they begin to feed on the wood, creating tunnels as they move through it. These tunnels can significantly compromise the integrity of wooden structures, leading to structural weakening over time.

The damage is particularly concerning in properties where wooden components are critical for support. As the larvae feed, they create extensive networks of tunnels that can reduce the strength of beams and other structural elements, making it important for pest control operators to identify and manage infestations effectively. The presence of these tiny tunnels is often indicative of a larger problem, highlighting the need for inspection and potential treatment to prevent further damage.

Other types of damage caused by pests, such as damage to metal frameworks or soil and plant roots, are not associated with the larval behavior of the death watch beetle, which is specifically centered on wood consumption and structural damage.
