Which beetle produces a rasping noise that can be heard by humans?

1. Lyctid

2. Bostrichid

3. Anobiid

4. Old House Borer

The correct answer is: Old House Borer

The Old House Borer is known for producing a distinctive rasping noise that can be heard by humans. This sound is created when the larvae of the beetle tunnel through wood, gnawing and scraping as they eat. The acoustic vibrations travel through the wood and can be loud enough to notice, particularly in a quiet environment. The ability to hear this rasping noise is significant as it can indicate a potential infestation. Homeowners and pest control professionals often rely on this auditory cue when inspecting for signs of the Old House Borer's presence in timber structures. In contrast, while other beetles like the Lyctid, Bostrichid, and Anobiid also infest wood and can cause damage, they do not produce the same audible rasping sounds. This lack of noise makes it more difficult to identify their presence early on, relying more on visual inspections or evidence of damage rather than audible cues. Thus, the distinct rasping noise of the Old House Borer sets it apart and makes it a notable concern in pest management.
