Do deathwatch beetles attack hardwoods and exhibit re-infestation?

The statement that deathwatch beetles attack hardwoods and exhibit re-infestation is accurate. Deathwatch beetles, specifically members of the Anobiidae family, are known to infest hardwoods, including timber and other wooden structures. The larvae of these beetles bore into the wood, leading to structural damage and the eventual weakening of the material.

In terms of re-infestation, deathwatch beetles can indeed return to an already infested area if the conditions remain favorable for their life cycle. This often happens in environments where there is still sufficient food source available, and if only some larvae or eggs were eliminated during previous treatments. This ability to reinfest and thrive in previously affected wood is a significant concern for pest control and management since it signifies that eradication efforts need to be thorough to prevent ongoing problems.

Understanding the behavior and life cycle of deathwatch beetles is vital for appropriate pest management strategies, particularly for properties at risk of infestation.
